Guys, everyone is crying that this doesn't do anything... on it's own, you're right. A spacer is part of a system (CAI, Ported Throttle Body, Spacer, Cams, Headers, Performance Muffler, Tune). This guy has most/all those things, so for him it works, yes. If your car is all stock, it won't.
but it’s not marketed that you need everything else with it. It’s marketed that it works on its own. if people honestly think that a device that might spin the air into the engine is doing anything …itd is absolutely comical.
I had a throttle body spacer on my 98 chevy ext cab 4x4 with a 5.7 vortec 350 small block. It helped out with the eco but also gave a lil better throttle response to the motor. I had a 3" spacer the spacer is manufactured to create better fuel and air mixture into the manifold so yes this aftermarket part does help in a small way
something else. I installed one of those twirly air intake spacers and the air was spinning so fast that a black hole was formed.The whole complete car was sucked into the intake manifold.
I'm pretty sure the idea behind a tbs is that it increases the volume of air inside the intake manifold, which creates a stronger vacuum pulling air into the throttle body. What this does is that it tricks the mass airflow sensor into thinking there's more air coming in than there actually is, which forces the ecu to adjust accordingly. This is where your power gain comes from. I doubt it will improve your fuel economy though
Okay it's been 8 years since you wrote this comment. That's enough time to learn why your comment is a horrible guess. The man you're right there with just a little more knowledge you would have had a plausible guess. It looks like you know just enough to make people think you know what you're talking about but not having enough knowledge to know you're wrong or know what you don't know. If you're going to make a guess like that go ahead and run some numbers first. Choose a manifold and find out what the displacement is. Then find out the volume increase with a throttle spacer. Then research if a 2 % increase would make a difference. Then ask yourself if this was the case then why are there not kits that move your throttle body two feet away. Furthermore a naturally aspirated engine is only going to pull in the amount of air as the cylinders displace. Regardless of the size of manifold given that it's not too small. The idea of the cyclone throttle body spacers is that because the cylinder will only pull in the same amount of volume the cyclone makes the air denser. Which sounds stupid when you say it. It's why they don't work. And even if they did work you would never know it. If they worked creating a more efficient engine they would be install the factory
The way I see it, it is one small component of a bigger system. So no single thing is going to make a huge difference. Just like saving pennies, eventually the benefits add up.
I installed a Helix power tower throttle body spacer on my 99 Blazer 4.3L Vortec V6 and I promise it makes a BIG difference. I would recommend at least a K&N filter with it. I also cut the small short inlet pipe to allow more air in the filter box. I upgraded to a CAI on mine so it helps but CAI really don't do much but allow more air flow in. I've also installed headers on mine with some improvement.
As previously mentioned, on old Carb cars the TBS works great and give real results. On a Fuel Injected system its practically useless. You're better off with a good quality "Cold Air Intake" and some plugs/wires. For big performance gains you'll need to focus on the internals of the engine.
I've used a few of these in the past, on fuel injected vehicles, and I've noticed it makes more of a difference with inline engines. and they also become more responsive over time as the computer 'relearns' itself. i got better mpg's and better low end torque. just my experience tho.
You can just reset the computer by disconnecting the battery terminal for a day and then when you start it back up again just use more throttle the first couple of days and the computer registers those figures.
The better option but still a small gain would be ditch the spacer and put a thermal gasket in it's place. It will help reduce intake temps which will give a small amount of power. In my opinion getting the spacer by itself is just making your intake even longer. Plus a thermal gasket that size is around 20-30 instead of paying 70+ for the spacer that does nothing
Basically it makes your intake manifold volume greater and puts the throttle body further away from the heads. The air now has to travel further to get into the head. It may just essentially take away horsepower on the top end to give you torque on the bottom end. The difference may be 1-2 ft tq.
You could also remove the screen from the front of your MAF sensor. Then take all the slack out of your throttle cable, and you will see a pretty good difference. I dont know if you have a throttle body butterfly restrictor, my 4.3 chevy v6 had one. I removed that as well, and my Astro van was a little quicker than normal. Then it got stolen, never got it back.
From what I have researched on it seems the style of the intake manifold can affect the gains or no gains you could get. That and other types of mods might be the main reason there is such gap on yes and no gains along with natural factors(humidity,temp ect). I can not for the life of me remember the name of the fluid effect but generally you have 2 streams, the inner and outer. The inner stream is where most of the volume comes from and the outer is the slower moving volume. What this device mimics and tries to do is alter the outer stream flow pattern. What this allows is the inner air to move around a corner more efficiently. As any kink or bend in flow direction will restrict the flow to a certain point. If your intake manifold has no bend or curve after the throttle body you may not see any difference as the air flow has no restriction other than the surface itself. Generally, polishing and removing any casting marks will lessen any restriction the surface gives to the flowing air before the point of fuel mixture. Some say this swirling effect allows the F/A to mix better, but I highly doubt that, not in a non carbed fuel injection. The effect created behind the TB is lost and/or diminished greatly as soon as it enters the main part of the manifold, plus fuel is added further down the line in injection systems not at the throttle body. If there is any increase to mix it would be minimal in my opinion. I would like to note that with a carburetor or EFI carbs will benefit from a tb spacer as it gives more time for the air and fuel to mix. I have theorized that if you create this same effect again at the top of the intake runners you could see a noticeable difference. How much of a bend and the length of the runner would probably affect this greatly along with the amount of air you can agitate without restricting air flow. How to go about this is another matter. A lot of intakes do not allow access to the top of the runners. There is generally enough room to polish and port match them, but you are generally out of luck to attempt this unless you have the ability to cut the manifold open and weld it back together or it is accessible by a removable panel. Luckily on my car the upper intake is in two parts and gives direct access to the top of the runners. I am searching for a junk yard upper and lower and I am going to attempt to create this effect on the runners along with port matching, removing casting marks and polishing. There is more than enough meat on the runners to engrave a swirling pattern in them. Unfortunately I do not have the funds to be able to pay to have several tunes and dyno runs along the way to test each thing I do to the intake. I can only test the final tune and dyno against known numbers with the same mods (aside what I do to the runners). I am no mechanical engineer nor a master in fluid dynamics. So if anyone reading this can correct me or give me tips to go in the right direction let me know.
Installed one on my 2017 GMC Sierra. Noticed minimal response to acceleration and lighter throttle feel. Overall, truck feels it goes with less effort. This combined with CAI, muffler delete and a chip tune.
I have a 02 silverado 5.3 L , and I tried the same spacer, got one of these's for free. Tried it and what a waste of time, NO improvement at all. Then I bought a SET some MSD red blaster coils , and that made a BIG difference. For simple bolt on aftermarket part, money well worth spent.
Put one on my 95 ZJ. I can say that I felt a good improvement. I don't have any numbers or any of that. Just saying that for me it worked and also got a little better gas mileage.
Hello, your outtakes mentioned U were unimpressed after driving for a spell. Did U ever reset you ECU so it recognized the upgrades you added? If you didn't your ECU is running on engine stats from pre-performance upgrades...food for thought. I installed a spacer yesterday and reset my ECU to recognize/re-calibrate to the new data generated from upgraded throttle body spacer, CAD intake system & Superflow muffler (89 XJ 4.0). Over the next 49 starts, my XJ will re-calibrate based on new data along w/my driving habits to optimize the system for the upgraded components. :)
Great input. I was hoping for a dyno comparison but if your butt dyno only feels marginal throttle response increase, it's likely an actual dyno run would show the same. Like so many "cheap" performance parts throttle body spacers are for those who are truly trying to squeeze every last pony out of their motor. Not really intended for the bolt-on crowd. Good info., thanks for sharing.
Austin Rausch its a placebo effect.. It feels more responsive because it's a shiney new part, and it cost money. Until actual dyno charts are put up, we will not know the gain, if any.
You should have try the Tornado, that improves fuel MPG from 0 MPG to 00.0 MPG, or better yet Slick 50 which reduces friction by not starting car or truck,......best vehicle I ever own that is good in fuel mileage, economical, low cost (no add ons) very low maintenance and environmental friendly is ........
Sometimes the seat of your pants feel is just fine and I appreciate your take on this product. My only issue is people calling SUV's and crossovers "trucks."
In the beginning of this video he says " i actually felt a difference I'm surprised "... at the end of the video " is it worth it, no not really" lol MY WORD this is what you call CLICK BAIT
I see a lot of comments stating these don't work it depends on your vehicle and what your after. It works if you want low end torque and smoother acceleration. I have used the two brands out there power aid and jet. With this key thing. NO cold air intake tubes and filter they don't add anything. Using a stock air box and the OEM k&n filter will give you the perfect amount of what you want.
Its more or less just an added part you would put on a build for some more results ex: you have a 4" intake w/ a performance intake manifold, bigger TB, and a good engineered TB spacer can have results to help the other mods for better airflox. You adding it to your stock air box w/ filter lol w/ nothing else is not worth it. Upgrading even a better intake system and a TB spacer should help out just in itself
I noticed a great improvement on my lifted Jeep Wrangler with the 4.0 inline 6 and 5 speed manual transmission because the engine struggled to spin the 33's at highway speeds in 5th gear without the spacer but after installing it I was able to use 5th gear and that made a huge jump in mpg. I also had many other upgrades on that Jeep as well including K&N air filter, Flowmaster exhaust and other similar bolt on accessories as well so I am sure those were a factor as well. Good luck
Everyone is looking for HP increase, but it's a spacer... reall great video because he detailed it exactly. It's to add fuel mileage, it's basically like a cheaper upgrade pf a Cold Air Intake... you want HP? Strip the engine and re build it. Lol people can't appreciate an informing video
It worked on my 05 3.5 L Tacoma 2WD. Robbed my top end speed but improved low end torque and acceleration. I also had it Unichipped with a Volant CAI, NGK Iridium plugs, magnaflow exhaust. I got it down to 0-60 in 7.06 seconds but I Rolled it 7 times haha. I miss my Taco.
They work depending on the design. Spacer plates on carburated motors back in the day would increase the time fuel would take to reach the manifold. And in turn reach the pistons for ignition. The concept of the spacer as was the taller manifolds is the fuel had more time to vaporize . In carburated motors the cold start would shoot cold fuel into the motor giving less efficiency. As the motor warms up the manifold get hot. When fuel hits it the fuel steams (vaporizes)and mixes more thoroughly with air to burn. This the plate would give more time for the fuel to do this and less raw fuel would hit the pistons. This giving more burn and efficiency. Now with injected motors? The throttle body shoots air into the manifold/plenum and the manifold depending on the design direct the air fuel mixture to the pistons. The injectors mist fuel that mixes with the air. The spacer if designed a certain way changes the direction at low throttle from where the butterfly is stirring the air up. You may feel a increase due the air being stirred up earlier due to the spacer. But? It can hurt more open throttle response or not change it at all as the air passes faster over the spacer. It can help the throttle body run cooler as its further and has a barrier from the manifold but as temps rise this benefit lessens. They can produce little benefits but are more for dressing up your motor than any huge gains that are expected. A larger throttle body would give better benefits as it allows more air inlet.
I saw 1 put on a Dino, it got onehalf horsepower and 8' pounds of torque but it's nothing you'll notice but when you add it all up with the rest it all adds up
For this product to work, one of these two things would need to happen. 1. It would have to increase the volume of air feeding the engine at any given moment. 2. It would have to increase the air velocity during a part of the rpm range or throughout the whole rpm range. This product can not do either of those things, from an engineering standpoint. I dont care what you think you feel. It just isnt possible. Any felt increase in power is purely placebo.
I've heard it said that the added length of travel in the intake system gives the airflow a chance to "clean up" so that it enters the manifold, traveling in an efficient way. In particular, the spiral throttle body spacers focus the air's movement into a spiraling motion that travels through the manifold better. I don't know about that. It seems a little fishy to me. However, I think about when you add the red straw to the WD-40 can and how it takes the flow from a spray to a stream and I wonder if, theoretically a throttle body spacer could have a similar effect. As an engineer, do you think there is any truth to that?
I have never used these but from a fluid dynamics perspective, there are 2 types of fluid flow, laminar and turbulent. Turbulent flow is like if you put a brick in a wind tunnel: the air currents would be moving in all different directions due to a brick not being very aerodynamic. Laminar flow is that same wind tunnel without a brick in it, it when a fluid is moving in a direction without resistance from obstructions. the throttle body can create obstructions in the air charge. The purpose of this product is to channel the air into a conical shape and decrease turbulent flow. This pulls a bigger vacuum in the intake piping and pulls more air into the system increasing air velocity. Furthermore laminar flow is far more efficient then turbulent flow and allows for more total air volume to enter the engine. That being said: I’d wager that if you have stock manifold, throttle, and intake pipe it won’t really do anything but on a fully built intake system you can expect a small power gain in the mid to high rpm range.
Someone did a dyno of a spacer it was like 3hp and 7 torque at wheels. If you port the throttle body in combination you'll get more. Same with exhaust and intake. The more to do to move air in combination they all work together to increas power. it does free up torque lower and broadens your "power band" if you will. You may 2hp extra per install. So air tb exhaust would be 6 plus the 3 of the spacer you're getting close to 10hp to the ground.
Spacers help getting air more efficient to the vehicle...might provide as much horse power as you may think but IT WILL help in MPG. Ypu can see this in vehicles that have digital MPG indicators.
NutriFIT nutritie si fitnes I highly doubt there was even a 3 hp improvement. the reason is, when people first started using this upgrade, it was on carb engines mounted in a vertical fashion. this increased the distance from the carb, to the intake runners, creating a "tunnel ram effect". this is simply not possible with a horizontally mounted throttle body
+no body you hit it on the head. With a carb, you have both fuel and air flowing thru a spacer. This is just air, it did nothing, people want to feel a difference, that why later he decided it's not worth it.
I had a 1996 Grand Cherokee 4.0 6 cyl inline and it always had issues pulling our tent trailer. I installed a short ram intake and a throttle body spacer and after that pulling the trailer was not a problem.
I work in R&D/Tech support for BBK and have tested many different throttlebody spacer's on many different late-model V8 applications. None of them have added even one horsepower and a few of them on Mopar applications have dropped up to 4 hp. These are real world controlled dyno tests. It's a bit of a shame really. These things are so easy to make with all of our capabilities but we can't and won't make them because they don't do anything for the customer. They're great for making money but we won't release anything that doesn't make real rear wheel horsepower. In some cases where our throttlebody is larger than the intake manifold's inlet, we do include a spacer that helps adapt the two different sizes with a smith transition but they are not standalone throttlebody spacers. Keep in mind that my comment doesn't apply to carbed motors. Only late model EFI.
It's more for carbureted engines.... the reason why it works there is because you add volume (air) and you place the carb up higher away from the heat source and gets cooler air which translates in more HP (nothing crazy couple tops). It does not really work with cars that have fuel injection as the ECU is doing all the work. I got both this is how i know
I had a 2000 gmc Sonoma with the 2.2l that I polished the throttle body, installed spacer, k&n drop in filter and modded the air box and I noticed a increase in power and mpg. the best mod I did to increase power and economy was removing the mechanical crank fan and installing electric fans. with all that done, I was getting 28mpg which is substantial compared to 23mpg average when I first got it! imo all those mods were worth it..
For those saying this is a waste of money, id like you to actually go buy one and try it instead of just talking, I installed this on my 01 jeep cherokee xj and obviously its not a huge difference but things I noticed right away was a louder start up, more responsive gas pedal, and when i punch it she just keeps on going instead of switching gears early like she used to before the spacer, more pickup speed for sure
Also my buddy was present when i installed it and he actually said these things before i had a chance to , if someone else can notice it then its doing the job i would definitely recommend, its not the one all modification that will make your engine run better its just an addition, and i wouldnt rely solely on power gains from just the spacer like i said it just adds a little something that wasnt there before
I think it all depends on the car. I tried one on my 4.2 Trailblazer and it did nothing. In fact, I seemed to lose fuel economy. I also have a dual catback exhaust and cold air intake, so a spacer may not have much effect. I also seem to have better throttle response without it. All in all, spacers aren't going to do much performance wise.
All you people are bashing throttle body spacers because it only helps during low/mid end rpms. Us people with real trucks (not 6 cylinder suvs) look for that kind of stuff, because it takes a lot of power for our engines too move heavy loads. Therefore, every little bit counts in the low/mid end
biggie biggs Oh come on now, im into it for the same kinda purpose, my 4.2 as my derby car hauler and all, and being an i6 twin cam or not, seek out that lower end lug myself.
I think that whether or not a spacer improves torque and/or mileage depends on what vehicle, engine, carb/TB, air cleaner and exhaust you have. I'm guessing that having improved intake air/exhaust flow, combined with the spacer increases the velocity of the intake air for better atomization of the air/fuel mixture and more complete combustion. For my '99 Dodge 5.9 with improved exhaust/cold air, it most definitely increased torque in the low to mid-range RPMs.
this is something you would want to add when going with a larger TB. the longer the spacer the more improvement you will get, Up to a certain point. Longer runners often yield better bottom end power. this is all you are doing here is adding a little bit more to the intake runners.
Thanks for the review, nice to know it made a little difference. I plan on an adapter for a larger throttle body. Should gain more than just throwing on a spacer with stock size throttle body.
What people don't understand is that spacers were designed for throttle bodies that have injectors not dry throttle bodies where the engine has a injector for each cylinder.
Depends on the vehicle. I had an 04 GTP and the throttle body on those are right above the exhaust cross over. Using a spacer helped drop intake temps.
The only way I can see this making a difference is by increasing the overall plenum volume and making slightly more air available to the runners. Longer intake runners will improve low end response and torque. The extra volume is so minor that the money could be saved and spent on a mod that would provide proven gains. the reality is that the design of the entire intake system varies so much between engines that simply adding a spacer like that may hold better gains for some and none for others simply due to design of other parts negating the intended effect of the spacer.
Installed a “PowerAid” (I think, it was red) TB spacer on a 2003 Wrangler w a 4.0L 6 cyl. I had 33” tires that completely robbed me of my 5th gear. I lost speed on any hill or incline and was forced to down shift to stay at 55-60 mph. After TB spacer I could maintain my speed on mild inclines and pass other cars while staying in 5th gear! Highly recommend K&N factory replacement filter with the spacer!
The "start it up and see what happens" activity can get exciting. Way back in the mid 80's I was working at a BMW Dealer. For some reason I had to pull off the air inlet to the throttle body (733i). It was an easy job and I decided to go to the restroom before pulling the car out. While in the restroom I here all this commotion in the shop,out I go. I find that the Service Advisor decided to pull the car out for me,wrong. I had put one of the big clamps on up side down and it prevented the throttle from closing, in fact it held it full open. Close call but we all went home that day.
I have a Tacoma 2004.. I added a throttle body spacer and cold air intake.. I was getting 11.4mpg now I’m getting 14.9mpg.. it really did improve my gas mileage
You got a 3.5 mile-per-gallon increase with just a TBS and a CAI !?? NAH. Mebbe you don't figure your gas mileage properly. If that were even POSSIBLE, Mr. Toyota would have put them on all their cars & trucks -- like YESTERDAY !!
Put one on my 2017 Ram 1500 with 5.7 Hemi. Totally robbed the low end torque. Caused the Economy light to stay on no matter how heavy I was in the throttle. Took it back off and viola power was restored. It was installed correctly as I have done quite a few. O-ring up and alignment pins lined up with no vacuum leaks.
If you do get a check engine light it's because you didn't reset the ECU and then drive it until it relearns all the shift points and fuel trim calculations. only then will you know if it feels the same way it did before
As A Auto Diesel Mech 35 years I have watch people put cold air intakes and spacers all kinds of junk and a lot of them do nothing to increase power.Cold air Intakes are the biggest joke Unless you are pulling the air out of a Ram air Duct through the hood and force feeding a large Volume of cool air there will be a lose of power.For all those that are in question I recommend that you do this. Ask to see a Dyno test on the vehicle you are planning to modify not any other vehicle but the car you are making the modification to.Also you want Before and after tests of any performace part under the same exact conditions including air intake temperature.This is one of the first steps for tuning a car.Next have your car dyno tested for a base line. Then when you are done with your changes have your car dyno tested and tuned if needed this will confirm you gain anything.This video is in no way proving this spacer works.Also no word of mouth even from trusted friends THE DYNO DOES NOT LIE.
I would disagree on most cold air intakes... Technically most aren't "cold air" because they sit in the engine bay OPEN to the heat, but SOME do come with heat shields and are mounted in bumpers etc. You do get an increase in HP and Torque because the stock (for most) are highly restrictive. Speaking from experience, my S10 had a box with a flat filter that was fed by a 3" opening into the box. I changed it to an AEM cold air intake and my throttle response and torque went up noticeably. No dyno numbers because I don't have that kind of time. But it does work.
DeFreshS10 First let me say I not trying to offend you but the increase in power that you think you felt is not detectable by any human being you would need a min of 50 HP before you would be able to notice a change .A 5-25 HP INCREASE can only be measured by a dyno or running down a track with times AND THE KEY IS SAME EXACT CONDITIONS.What I will say if you notice any change in your vehicle it would be in fuel economy if you were checking it from the beginning.So with This said it would of been mainly from going from a paper air filter to a cotton air filter this is were you increase of power would come from.As for cold air tubing this is a restriction by design Any vehicle pulls a given CUBIC FOOT A MINUTE (CFM) so Cold air induction has two flaws,First being in order to get the coolest air into the engine means we have to go out in front of the radiator.So when we make just one 90 deg bend we need to 6 feet of straight tubing to regain laminar flow.So now we move to the short design which means our air intake is right next to the radiator and we pick up the heat from under the hood.I prefer a ram air system into a short run the benefits I pick up is I get a pressure increase as the vehicle accelerates. second if I am racing there old school tricks to cool that air down further and correct the flow of air.Also I do not pick up ambient heat from the radiator or engine compartment as a ram air is truly sealed.What are your thoughts.
I would PATENTLY disagree with your claim of not being able to "feel" anything under 50HP. My stock motor has ~170 HP... and that a 10hp gain would be a 6% gain in power. Not only that, you INCREASE the power at low end RPM range. Now a CAI on a motor with ~250+ would be insignificant and you most likely wouldn't feel it. *"What I will say if you notice any change in your vehicle it would be in fuel economy if you were checking it from the beginning"* yes. there was an Increase in MPG, though only about 1.5 or so. But I could still feel the difference in low end power. The amount of air going into the engine is measured. If your ECU recognized more air, it could dump more fuel (provided you have a tune). My intake pipe was actually larger than stock and longer (regaining laminar flow) so CFM increases.
DeFreshS10 DeFreshS10 Again I would disagree with even a on any engine in horsepower gains not even the pros can feel a 10 HP gain.The only way to see a increase is through time.If you take a 10 hp engine and loaded it down until it stalled you would see that it is a small amount of power. Now if you are talking B/TORQUE Then you might just might feel a difference.As far as a longer larger CAI TUBE you lose efficiency and laminar flow as there tends to be more bends in the pipe.I have had this debate with others and like I said if all things be equal the proof is on the dyno.I deal with engineers from JOHNSON MATTHEY,CCC , CUMMINS, GM FORD ETC ALL telling us how great there equipment is yntil we prove or dis prove it on a Class 8 emmission laboratory DYNOMETER.
They make the intake shorter or longer for different purposes, both changes the Charakteristik of hp and torgue thats why some have a changeable intake like Dodge 392 engines
Yes there's a nice aggressive tone on mine as well under wide open throttle. The Bullydog Platinum GT just enhanced that with even better throttle response on the premium tune but didn't see any difference in MPG yet
I mean, if you added a cold air intake, larger throttle body, and a full exhaust system, it may be good to slap this thing on for a little extra performance.🤷🏻♂️
I have a 2006 Chevy trailblazer in-line 6 4.2 vorthec I got an air raid worth 126 dollars, it was worth the money I have no intake just stock and yes when you come out from a complete stop I goes much faster way faster, and yes it makes a little whistle like turbo , the only bad thing is the spacers that comes with the package they are not good they strip and sucks so I took them off but yes it’s worth it
There is a video posted titled "par Honda Accord - throttle body spacer dyno" this is a before and after dyno on a fuel injected Honda Accord. Results WOT were 3-4 horsepower and 7-8 ft lbs torque. He also tested mid range power on the dyno and made an overall 5 hp / 5 ft lbs of torque. That makes it at best (on the Honda) $20-$25 per pony. Now the debate is that output on a dyno can vary. Was the slight gain from the tbs or was it an environmental factor like temperature humidity ect.
dasllamas, I agree with your thoughts on how Darkness can vary each pool. Hard to say at the spacer made a difference but they do sound really awesome with that whistle sound!
Billblackeye there are many parts that are better for your car. They do It because of price. Production cars are literally done so if they can save a dollar a car they will because after they sell a million cars they saved a million dollars.
On a Carbourated or Throttle Body Injection fuel system, they ABSOLUTELY make a difference in power because it actually causes the fuel and air to mix much better. Modern cars are multiport or direct injection, so the fuel mixture does not pass through the spacer at all and does not get better mixed into the air. The only way it could make a difference on a modern car would be by increasing the intake volume... but not by much.
my thoughts: if you want to do everything, or you are already going to have everything apart, then this is something to do, BUT it's not worth it to do it on it's own....
It showed improvement because it did a throttle body relearn. Everytime I do a throttle body reset on my Ram hemi it becomes more responsive until the ecu learns and does it's programming.
All it really does is increase the DISTANCE the air travels to get into the engine and creates a slight restriction in airflow. By doing this though, you increase air velocity so at low rpm you might gain some slight low end tq but it is quickly negated as the rpms rise and actually hurts horsepower because now the air is traveling farther and is more restricted.
This is kinda wrong, the spacer would increase the plenum behind the TB area there for the "restriction" wouldn't be an issue since these engines don't consume the plenum area that quick (which is where the cylinder is directly pulling air from). You also wouldn't see any more low end torque but rather an increase in throttle response because the air would be moving from the tb to the intake valve quicker. Which is the take away from this, power gains aren't there unless the fuel flows through it too, but it will have a very slight difference in throttle response.
Maybe on startup the air takes a tad bit slower to reach the chamber, causing a bit slower startup, depending on the spacer size. But air is a gas, which is an unlimited source, and is consistently flowing into the combustion chamber after startup, granted the filter, throttle body, and engine is working properly. I personally don't use throttle body spacers or plenum spacers that's over a 1/4 inch, in conjunction with other parts. The only thing these parts improve when used by themselves is throttle response. Horsepower and torque gains are a hit and miss.
If this were a carb spacer then yes, it is a definite upgrade. A carb spacer allows both fuel and air to pass which usually increases torque fairly well with little gains to actual HP. This application however, being fuel injected only passes air, half of what is needed for substantial gains if any. I would venture to say at best maybe 1/2 HP and 1-2 more torque, but I kind of have my doubts of any real gains.
Had a TBS on my 03 gmc sierra 5.3l vortec and i loved mine, it did make a whistle noise that was very audible, i liked it though, between the Aftermarket intake system making a audible sucking noise mixed with a whistle from the TBS it gave the motor a more performance built sound to it, it did seem to add maybe 1mpg on the truck, but its a cheap little part to help improve throttle response if you buy the spacer kits that actually are grooved like a gun barrel so it works to "speed up" the induction and increases the total air took in while making it mix with the fuel more rapidly and easier. If your spacer is a block of metal, its wrong, if your CIA is not in a box that is ported to take in air from the outer edge of the engine bay you have a hot air intake not a cold air intake. my 5.3l vortec had an AFE CIA with my TBS (forgot brand) and i ran a bullydog tripple gt tuner on it and i pulled away from other gas burners off the line and held it, when i had my 40l6e built by Jasper that had a heavy shift kit, 16 kevlar clutches instead of the stock like 4-6 it has, high volume oil capacity and high fluid flow kit with trans cooler, better valve body and planetary gear, it cost me around $4,000 total in labor and parts using my own Core, it became a shit show when racing, walking them constantly. IF your gonnna buy parts BUY CORRECT AND QUALITY
J Bouchard it sort of does because street racing is illegal, No professional would be watching this and you don't really need it. Altering the volume of your intake is for going faster than 200mph.
Daëmon I'm sure that it does something. It increases the volume of your intake. I'm sure that does something. I don't personally know what it is but I do know that unless you have a finely-tuned stroker Engine with big giant heads on it then it's not going to make that much of a difference. Several things are run on the vacuum inside of your intake. Those might be affected depending on the increase in volume. There will be no vacuum at lower speeds which means certain things in your electronics will work different. Anyting that operates based on the vacuum and your intake will do whatever it does as the vacuum approaches 0 at a sooner time and that is not necessarily a good thing but in a larger engines with more horsepower you might need that because they suck an air way faster and more air. That is the reason that you would need to expand the volume of your intake. But you probably think that you can hear noises and that it means something from an engine that was manufactured to reduce noise and a sideways and not rear wheel drive. I personally pay more attention to what kind of vibration at makes and where it is coming from because I can't hear s*** inside of my car.
I have 2005 GMC ENVOY XL 4.2 I used the Airaid throttle body spacer alone with K&N cold air intake & removed both factory mufflers and installed Cherry Bomb 3" inlet outlet glasspack the longest one I could find its Bolt on flange to catalytic converter adding dual tips like on the Dodge challenger soon nxt going to buy the jet performance stage 2 chip
I think you misconfuse intake spacer vs 'plastic' or 'plenum' ones. The real one's supposed to cool down your complete inlet on your engine from being warmed up, so your cold air does'nt get soaked in heat with a hot intake. A spacer in between (for example between block and intake) would drop the air inlet temperature a few degrees producing more HP cause of better ignition. But all these mods are 0.1% increase, you should simply go for a bigger turbo or compressor based on what you flavor is. The thing in this video only shows a threaded intake spacer, which would 'warp' the air a little more providing a little more torque, but nothing serious and proberly lose power on the high-end.
KronosSlots you’re right about losing in the high end but I have a AFE throttle body spacer which makes a huge difference at low end, but I do have a full stage 2 cold air intake by AFE which replaces both the resonator and box intake and the combination of the two gives insane throttle response and its dry fuel injection not carburetor
Thanks for your informative thorough video. Was ready to buy spacer and install on my 3.6 Jeep Wrangler. Like you I have a cold air intake and performance exhaust system. Which made my Jeep considerably faster... But being an old Gearhead as I am, We always want more POWER.. Great video.. Thanks from Chris
I have a 04 6.0 Silverado 5 speed with edge programer, and cold air I got 16 mpg, added the throttle body spacer and went up to 19. didn't change my driving or anything.
I have one on my truck from American trucks.com. I have a whistle but it’s nice, have cold air intake and full exhaust. Truck is a Silverado 4.8 with headers
Thanks for the video Jeff. I have an '06 Envoy with a 4.2L. I'm trying to find the right combo of parts to get a lot better performance and of course, better gas mileage. I was looking at the Taylor Cable Helix Power Tower PLUS Throttle Body Spacer. It's a little pricey at $115, but with an AeroTurbine muffler (which I know works) since I already have 3" pipes, a decent cold air kit, and a Jet Stage II Power Module, I think I'm going to be in pretty good shape. What are your thoughts on this combo??? What are your thoughts on boring the throttle body?
+Robert Robinson I'm not familiar with boring the throttle body so I can't offer any insight on that. If you have good experiences with that muffler then you should be OK. I recommend the K&N cold air kit.

Well, Bob, I have bought, installed, and tested the Taylor "Power Tower" and also a "Power Module", and BOTH of them are over-priced and completely worthless on my Port-type, Fuel Injected, V-8 engine. Those "power modules" and high-performance "chips" are a total SCAM -- there is NO CHIP inside, just a small resistor that tricks the computer into thinking that the intake air is colder than it actually is, so it adds more fuel. It's a dumb-ass idea, because your computer adjusts the Air/Fuel ratio , according to the signals from the O2 sensors. Clever advertising and a lack of oversight allows companies to exaggerate their claims, or even LIE to their potential customers -- it's capitalism - the American way !!
hojo70 Why would it matter? You already sound like the type that even if he did get a dyno you'd still not believe it. There's plenty of forums showing dyno proofed TBS. UTFSE noob
I've been installing these things paired with K&N intake kits for years and i heard mixed reviews from my customers, they say either it does nothing at all or it improved fuel economy. I personally wouldnt waste my money on one
I have the same truck and im about to order the same part, thank you. Im really tryin to bolt on and do as much as I can with my 4.2L I need more power
Holly crap DAna miller, are you kidding me, 11 to 19mpg, because you put a 1/2" thicker spacer.. Do you think we are all that dumb?The worst part about these companies ripping off people, are those that get suckered so hard into believing the hype, you will argue for the product and get others to take a chance and then waster their money also. How dare You!? Hmm, I feel it in my pants, I don't know anything about engines or how they work, but I know this piece of metal has the power greater than Jesus. Hmm, the factory doesn't use these cause they love paying the government EPA fines for failure to meet gas mileage regulations on every single truck they make. COME ON! Please, just go ask someone who knows how engines work, not just the guy at Jiffy Lube who only changes oil. You need to talk to someone that understands how a motor works and can explain it to you.

Thanks...I just ordered six! All going into the same car. Huge gains here I come!!
Lol
That's like 200hp on spacers yo
Dont forgot to add stickers for 20 extra hp
Good think it has racing blue
You won't be able to pass a gas station without filling up. Also, tire cost because of all the power you will burn the tires off every time.
Guys, everyone is crying that this doesn't do anything... on it's own, you're right. A spacer is part of a system (CAI, Ported Throttle Body, Spacer, Cams, Headers, Performance Muffler, Tune). This guy has most/all those things, so for him it works, yes. If your car is all stock, it won't.
but it’s not marketed that you need everything else with it. It’s marketed that it works on its own. if people honestly think that a device that might spin the air into the engine is doing anything …itd is absolutely comical.
I had a throttle body spacer on my 98 chevy ext cab 4x4 with a 5.7 vortec 350 small block. It helped out with the eco but also gave a lil better throttle response to the motor. I had a 3" spacer the spacer is manufactured to create better fuel and air mixture into the manifold so yes this aftermarket part does help in a small way
something else.
I installed one of those twirly air intake spacers and the air was spinning so fast that a black hole was formed.The whole complete car was sucked into the intake manifold.
Anthony Smith hahahha

Kyore Thanks bro!
What about in conjunction with intake and other bolt on mods?
🙏
Not the hero we needed but the hero we deserved 💪🏼
Good man
I'm pretty sure the idea behind a tbs is that it increases the volume of air inside the intake manifold, which creates a stronger vacuum pulling air into the throttle body. What this does is that it tricks the mass airflow sensor into thinking there's more air coming in than there actually is, which forces the ecu to adjust accordingly. This is where your power gain comes from. I doubt it will improve your fuel economy though
how about no , 100% wrong
Okay it's been 8 years since you wrote this comment. That's enough time to learn why your comment is a horrible guess. The man you're right there with just a little more knowledge you would have had a plausible guess. It looks like you know just enough to make people think you know what you're talking about but not having enough knowledge to know you're wrong or know what you don't know.
If you're going to make a guess like that go ahead and run some numbers first. Choose a manifold and find out what the displacement is. Then find out the volume increase with a throttle spacer. Then research if a 2 % increase would make a difference.
Then ask yourself if this was the case then why are there not kits that move your throttle body two feet away.
Furthermore a naturally aspirated engine is only going to pull in the amount of air as the cylinders displace. Regardless of the size of manifold given that it's not too small. The idea of the cyclone throttle body spacers is that because the cylinder will only pull in the same amount of volume the cyclone makes the air denser. Which sounds stupid when you say it. It's why they don't work. And even if they did work you would never know it. If they worked creating a more efficient engine they would be install the factory
The way I see it, it is one small component of a bigger system. So no single thing is going to make a huge difference. Just like saving pennies, eventually the benefits add up.
You can get another one 200 years from now .
Oh thank you. I added this spacer to my car and now it will lift the front wheels of the ground.
LOL
Your car: FWD

Nice save 😎👍

I installed a Helix power tower throttle body spacer on my 99 Blazer 4.3L Vortec V6 and I promise it makes a BIG difference. I would recommend at least a K&N filter with it. I also cut the small short inlet pipe to allow more air in the filter box. I upgraded to a CAI on mine so it helps but CAI really don't do much but allow more air flow in. I've also installed headers on mine with some improvement.
Yeah but the aluminium blue color makes your engine bay look nice.
landen hamilton logic of a ricer
I'm just fucking around chill
ben richard dumbass your saying someone who actually tunes is a ricer? fuck off
landen hamilton it does
Trevor Johnson nb
As previously mentioned, on old Carb cars the TBS works great and give real results. On a Fuel Injected system its practically useless. You're better off with a good quality "Cold Air Intake" and some plugs/wires. For big performance gains you'll need to focus on the internals of the engine.
I've used a few of these in the past, on fuel injected vehicles, and I've noticed it makes more of a difference with inline engines. and they also become more responsive over time as the computer 'relearns' itself. i got better mpg's and better low end torque. just my experience tho.
You can just reset the computer by disconnecting the battery terminal for a day and then when you start it back up again just use more throttle the first couple of days and the computer registers those figures.
The better option but still a small gain would be ditch the spacer and put a thermal gasket in it's place. It will help reduce intake temps which will give a small amount of power. In my opinion getting the spacer by itself is just making your intake even longer. Plus a thermal gasket that size is around 20-30 instead of paying 70+ for the spacer that does nothing
Basically it makes your intake manifold volume greater and puts the throttle body further away from the heads. The air now has to travel further to get into the head. It may just essentially take away horsepower on the top end to give you torque on the bottom end. The difference may be 1-2 ft tq.
You could also remove the screen from the front of your MAF sensor. Then take all the slack out of your throttle cable, and you will see a pretty good difference. I dont know if you have a throttle body butterfly restrictor, my 4.3 chevy v6 had one. I removed that as well, and my Astro van was a little quicker than normal. Then it got stolen, never got it back.
Faster than gone
What's the advantages of removing maf front screen?
From what I have researched on it seems the style of the intake manifold can affect the gains or no gains you could get. That and other types of mods might be the main reason there is such gap on yes and no gains along with natural factors(humidity,temp ect).
I can not for the life of me remember the name of the fluid effect but generally you have 2 streams, the inner and outer. The inner stream is where most of the volume comes from and the outer is the slower moving volume. What this device mimics and tries to do is alter the outer stream flow pattern. What this allows is the inner air to move around a corner more efficiently. As any kink or bend in flow direction will restrict the flow to a certain point. If your intake manifold has no bend or curve after the throttle body you may not see any difference as the air flow has no restriction other than the surface itself. Generally, polishing and removing any casting marks will lessen any restriction the surface gives to the flowing air before the point of fuel mixture.
Some say this swirling effect allows the F/A to mix better, but I highly doubt that, not in a non carbed fuel injection. The effect created behind the TB is lost and/or diminished greatly as soon as it enters the main part of the manifold, plus fuel is added further down the line in injection systems not at the throttle body. If there is any increase to mix it would be minimal in my opinion. I would like to note that with a carburetor or EFI carbs will benefit from a tb spacer as it gives more time for the air and fuel to mix.
I have theorized that if you create this same effect again at the top of the intake runners you could see a noticeable difference. How much of a bend and the length of the runner would probably affect this greatly along with the amount of air you can agitate without restricting air flow. How to go about this is another matter. A lot of intakes do not allow access to the top of the runners. There is generally enough room to polish and port match them, but you are generally out of luck to attempt this unless you have the ability to cut the manifold open and weld it back together or it is accessible by a removable panel.
Luckily on my car the upper intake is in two parts and gives direct access to the top of the runners. I am searching for a junk yard upper and lower and I am going to attempt to create this effect on the runners along with port matching, removing casting marks and polishing. There is more than enough meat on the runners to engrave a swirling pattern in them. Unfortunately I do not have the funds to be able to pay to have several tunes and dyno runs along the way to test each thing I do to the intake. I can only test the final tune and dyno against known numbers with the same mods (aside what I do to the runners).
I am no mechanical engineer nor a master in fluid dynamics. So if anyone reading this can correct me or give me tips to go in the right direction let me know.
Would have liked to see the result numbers lol. 3 year comment I know I know.
Installed one on my 2017 GMC Sierra. Noticed minimal response to acceleration and lighter throttle feel. Overall, truck feels it goes with less effort. This combined with CAI, muffler delete and a chip tune.
You’re not gonna see any difference on a GDI engine. If you think you do, it’s 100% placebo.
I have a 02 silverado 5.3 L , and I tried the same spacer, got one of these's for free. Tried it and what a waste of time, NO improvement at all.
Then I bought a SET some MSD red blaster coils , and that made a BIG difference. For simple bolt on aftermarket
part, money well worth spent.
Put one on my 95 ZJ. I can say that I felt a good improvement. I don't have any numbers or any of that. Just saying that for me it worked and also got a little better gas mileage.
Same with my 92 XJ
Hello, your outtakes mentioned U were unimpressed after driving for a spell. Did U ever reset you ECU so it recognized the upgrades you added? If you didn't your ECU is running on engine stats from pre-performance upgrades...food for thought. I installed a spacer yesterday and reset my ECU to recognize/re-calibrate to the new data generated from upgraded throttle body spacer, CAD intake system & Superflow muffler (89 XJ 4.0). Over the next 49 starts, my XJ will re-calibrate based on new data along w/my driving habits to optimize the system for the upgraded components. :)
Great input. I was hoping for a dyno comparison but if your butt dyno only feels marginal throttle response increase, it's likely an actual dyno run would show the same. Like so many "cheap" performance parts throttle body spacers are for those who are truly trying to squeeze every last pony out of their motor. Not really intended for the bolt-on crowd. Good info., thanks for sharing.
+Austin Rausch thank you
Austin Rausch its a placebo effect.. It feels more responsive because it's a shiney new part, and it cost money. Until actual dyno charts are put up, we will not know the gain, if any.
You should have try the Tornado, that improves fuel MPG from 0 MPG to 00.0 MPG, or better yet Slick 50 which reduces friction by not starting car or truck,......best vehicle I ever own that is good in fuel mileage, economical, low cost (no add ons) very low maintenance and environmental friendly is ........
Lol
on a 2000 4cyl wrangler thats grossly underpowered it was a major improvement
Sometimes the seat of your pants feel is just fine and I appreciate your take on this product. My only issue is people calling SUV's and crossovers "trucks."
@Beaf Supreme as long as it gets you from point A to z
In the beginning of this video he says " i actually felt a difference I'm surprised "... at the end of the video " is it worth it, no not really" lol MY WORD this is what you call CLICK BAIT
I see a lot of comments stating these don't work it depends on your vehicle and what your after. It works if you want low end torque and smoother acceleration. I have used the two brands out there power aid and jet. With this key thing. NO cold air intake tubes and filter they don't add anything. Using a stock air box and the OEM k&n filter will give you the perfect amount of what you want.
Its more or less just an added part you would put on a build for some more results ex: you have a 4" intake w/ a performance intake manifold, bigger TB, and a good engineered TB spacer can have results to help the other mods for better airflox. You adding it to your stock air box w/ filter lol w/ nothing else is not worth it. Upgrading even a better intake system and a TB spacer should help out just in itself
I noticed a great improvement on my lifted Jeep Wrangler with the 4.0 inline 6 and 5 speed manual transmission because the engine struggled to spin the 33's at highway speeds in 5th gear without the spacer but after installing it I was able to use 5th gear and that made a huge jump in mpg. I also had many other upgrades on that Jeep as well including K&N air filter, Flowmaster exhaust and other similar bolt on accessories as well so I am sure those were a factor as well. Good luck
Gotta do the 12 hole injectors from ksuspension too makes big difference
Have you considered using multiple spacers? I think that could be a fun before and after with some repeatable, measurable testing...
Everyone is looking for HP increase, but it's a spacer... reall great video because he detailed it exactly. It's to add fuel mileage, it's basically like a cheaper upgrade pf a Cold Air Intake... you want HP? Strip the engine and re build it. Lol people can't appreciate an informing video
It worked on my 05 3.5 L Tacoma 2WD. Robbed my top end speed but improved low end torque and acceleration. I also had it Unichipped with a Volant CAI, NGK Iridium plugs, magnaflow exhaust. I got it down to 0-60 in 7.06 seconds but I Rolled it 7 times haha. I miss my Taco.
7 times. WOW! I'm glad you're ok.
They work depending on the design. Spacer plates on carburated motors back in the day would increase the time fuel would take to reach the manifold. And in turn reach the pistons for ignition. The concept of the spacer as was the taller manifolds is the fuel had more time to vaporize . In carburated motors the cold start would shoot cold fuel into the motor giving less efficiency. As the motor warms up the manifold get hot. When fuel hits it the fuel steams (vaporizes)and mixes more thoroughly with air to burn. This the plate would give more time for the fuel to do this and less raw fuel would hit the pistons. This giving more burn and efficiency. Now with injected motors? The throttle body shoots air into the manifold/plenum and the manifold depending on the design direct the air fuel mixture to the pistons. The injectors mist fuel that mixes with the air. The spacer if designed a certain way changes the direction at low throttle from where the butterfly is stirring the air up. You may feel a increase due the air being stirred up earlier due to the spacer. But? It can hurt more open throttle response or not change it at all as the air passes faster over the spacer. It can help the throttle body run cooler as its further and has a barrier from the manifold but as temps rise this benefit lessens. They can produce little benefits but are more for dressing up your motor than any huge gains that are expected. A larger throttle body would give better benefits as it allows more air inlet.
I saw 1 put on a Dino, it got onehalf horsepower and 8' pounds of torque but it's nothing you'll notice but when you add it all up with the rest it all adds up
For this product to work, one of these two things would need to happen.
1. It would have to increase the volume of air feeding the engine at any given moment.
2. It would have to increase the air velocity during a part of the rpm range or throughout the whole rpm range.
This product can not do either of those things, from an engineering standpoint. I dont care what you think you feel. It just isnt possible. Any felt increase in power is purely placebo.
I've heard it said that the added length of travel in the intake system gives the airflow a chance to "clean up" so that it enters the manifold, traveling in an efficient way. In particular, the spiral throttle body spacers focus the air's movement into a spiraling motion that travels through the manifold better. I don't know about that. It seems a little fishy to me. However, I think about when you add the red straw to the WD-40 can and how it takes the flow from a spray to a stream and I wonder if, theoretically a throttle body spacer could have a similar effect. As an engineer, do you think there is any truth to that?
I have never used these but from a fluid dynamics perspective, there are 2 types of fluid flow, laminar and turbulent. Turbulent flow is like if you put a brick in a wind tunnel: the air currents would be moving in all different directions due to a brick not being very aerodynamic. Laminar flow is that same wind tunnel without a brick in it, it when a fluid is moving in a direction without resistance from obstructions. the throttle body can create obstructions in the air charge. The purpose of this product is to channel the air into a conical shape and decrease turbulent flow. This pulls a bigger vacuum in the intake piping and pulls more air into the system increasing air velocity. Furthermore laminar flow is far more efficient then turbulent flow and allows for more total air volume to enter the engine. That being said: I’d wager that if you have stock manifold, throttle, and intake pipe it won’t really do anything but on a fully built intake system you can expect a small power gain in the mid to high rpm range.
Someone did a dyno of a spacer it was like 3hp and 7 torque at wheels. If you port the throttle body in combination you'll get more. Same with exhaust and intake. The more to do to move air in combination they all work together to increas power. it does free up torque lower and broadens your "power band" if you will. You may 2hp extra per install. So air tb exhaust would be 6 plus the 3 of the spacer you're getting close to 10hp to the ground.
I machined my own a few years back. It did nothing that I could tell.
It was fun making it though. I even sold it to a guy for 20 bucks.
delano62 WIN✌🏽🔰
Thanks for the cheap price, i ended up mass producing it and ended up w a couple mil.
Spacers help getting air more efficient to the vehicle...might provide as much horse power as you may think but IT WILL help in MPG. Ypu can see this in vehicles that have digital MPG indicators.
Dyno numbers before and after please
some TH-cam did a dyno run and it's little improvement. about 3 more hp and 7 torqe. he's right about little improvement
what car was the test done on?
NutriFIT nutritie si fitnes I highly doubt there was even a 3 hp improvement. the reason is, when people first started using this upgrade, it was on carb engines mounted in a vertical fashion. this increased the distance from the carb, to the intake runners, creating a "tunnel ram effect". this is simply not possible with a horizontally mounted throttle body
+no body you hit it on the head. With a carb, you have both fuel and air flowing thru a spacer. This is just air, it did nothing, people want to feel a difference, that why later he decided it's not worth it.
Joshua Barton yup, and you can't convince many, if not most of these people. too many think the fast and furious is actually based in fact...lol
I had a 1996 Grand Cherokee 4.0 6 cyl inline and it always had issues pulling our tent trailer. I installed a short ram intake and a throttle body spacer and after that pulling the trailer was not a problem.
I work in R&D/Tech support for BBK and have tested many different throttlebody spacer's on many different late-model V8 applications. None of them have added even one horsepower and a few of them on Mopar applications have dropped up to 4 hp. These are real world controlled dyno tests. It's a bit of a shame really. These things are so easy to make with all of our capabilities but we can't and won't make them because they don't do anything for the customer. They're great for making money but we won't release anything that doesn't make real rear wheel horsepower. In some cases where our throttlebody is larger than the intake manifold's inlet, we do include a spacer that helps adapt the two different sizes with a smith transition but they are not standalone throttlebody spacers. Keep in mind that my comment doesn't apply to carbed motors. Only late model EFI.
+Bryan Rogers thanks for your feedback. I'm thinking about removing it to see if I notice any difference now that it's been on awhile.
It's more for carbureted engines.... the reason why it works there is
because you add volume (air) and you place the carb up higher away from
the heat source and gets cooler air which translates in more HP (nothing
crazy couple tops). It does not really work with cars that have fuel
injection as the ECU is doing all the work.
I got both this is how i know
Did you happen to ever get around to removing it and seeing if the spacer was doing anything for you?
But do they do anything for gas mileage?
I think these worked on carb. engines somewhat. The only way to modify performance on an EFI is to modify the computer's programming.
I had a 2000 gmc Sonoma with the 2.2l that I polished the throttle body, installed spacer, k&n drop in filter and modded the air box and I noticed a increase in power and mpg. the best mod I did to increase power and economy was removing the mechanical crank fan and installing electric fans. with all that done, I was getting 28mpg which is substantial compared to 23mpg average when I first got it! imo all those mods were worth it..
I stopped taking the video seriously when he pointed his "cold air intake" located in the engine bay LOL
For those saying this is a waste of money, id like you to actually go buy one and try it instead of just talking, I installed this on my 01 jeep cherokee xj and obviously its not a huge difference but things I noticed right away was a louder start up, more responsive gas pedal, and when i punch it she just keeps on going instead of switching gears early like she used to before the spacer, more pickup speed for sure
Also my buddy was present when i installed it and he actually said these things before i had a chance to , if someone else can notice it then its doing the job i would definitely recommend, its not the one all modification that will make your engine run better its just an addition, and i wouldnt rely solely on power gains from just the spacer like i said it just adds a little something that wasnt there before
I think it all depends on the car. I tried one on my 4.2 Trailblazer and it did nothing. In fact, I seemed to lose fuel economy. I also have a dual catback exhaust and cold air intake, so a spacer may not have much effect. I also seem to have better throttle response without it. All in all, spacers aren't going to do much performance wise.
I have a jet spacer for my 2003 GMC envoy 4.2,but i used it for installation of nos jets on the spacer worked perfect.
All you people are bashing throttle body spacers because it only helps during low/mid end rpms. Us people with real trucks (not 6 cylinder suvs) look for that kind of stuff, because it takes a lot of power for our engines too move heavy loads. Therefore, every little bit counts in the low/mid end
"Real trucks(not 6 cyl or suv)" might be the douchiest comment ive read yet
biggie biggs Oh come on now, im into it for the same kinda purpose, my 4.2 as my derby car hauler and all, and being an i6 twin cam or not, seek out that lower end lug myself.
I have to say that those 4.2 triailblazers pull! Great experience pulling 30ft Rv trailer.
I think that whether or not a spacer improves torque and/or mileage depends on what vehicle, engine, carb/TB, air cleaner and exhaust you have. I'm guessing that having improved intake air/exhaust flow, combined with the spacer increases the velocity of the intake air for better atomization of the air/fuel mixture and more complete combustion. For my '99 Dodge 5.9 with improved exhaust/cold air, it most definitely increased torque in the low to mid-range RPMs.
I completely agree that there are a lot of variables and every vehicle is different.
this is something you would want to add when going with a larger TB. the longer the spacer the more improvement you will get, Up to a certain point. Longer runners often yield better bottom end power. this is all you are doing here is adding a little bit more to the intake runners.
it's obvious that you read too many tuner magazines and have not spent enough time turning wrenches..
+David Soule damn that was funny...
Thanks for the review, nice to know it made a little difference. I plan on an adapter for a larger throttle body. Should gain more than just throwing on a spacer with stock size throttle body.
Why use the resonator ? Just connect the air filter direct to the throttle body ?
there you go, lmao
TheUpandoveragain that might actually add power unlike this added wheight.
I was thinking the same. Why bother with an aftermarket intake if you keep that restrictive resonator.
What people don't understand is that spacers were designed for throttle bodies that have injectors not dry throttle bodies where the engine has a injector for each cylinder.
Chris Sheppard never knew this. Didnt even know these spacers existed. Only the ones used for NOS kits
Depends on the vehicle. I had an 04 GTP and the throttle body on those are right above the exhaust cross over. Using a spacer helped drop intake temps.
Shawn Van Meeteren I j NJ I hi
The only way I can see this making a difference is by increasing the overall plenum volume and making slightly more air available to the runners. Longer intake runners will improve low end response and torque. The extra volume is so minor that the money could be saved and spent on a mod that would provide proven gains. the reality is that the design of the entire intake system varies so much between engines that simply adding a spacer like that may hold better gains for some and none for others simply due to design of other parts negating the intended effect of the spacer.
rustynuggets considerinf that runners are only really with carbs that are vertical. on a horizontal, it's negligible.
Dylan Baxter well that's just not true.
Yeah, not true at all. runner length is definitely a tunable thing for cars regardless of position.
rustynuggets also those spacers are rifled so that the air spins. Guns have rifled barrels to improve performance, so ai can see why these may work
rustynuggets Rusty You are making a smaller space for the air. Google "How does air velocity affects torque?"
Installed a “PowerAid” (I think, it was red) TB spacer on a 2003 Wrangler w a 4.0L 6 cyl. I had 33” tires that completely robbed me of my 5th gear. I lost speed on any hill or incline and was forced to down shift to stay at 55-60 mph. After TB spacer I could maintain my speed on mild inclines and pass other cars while staying in 5th gear! Highly recommend K&N factory replacement filter with the spacer!
Glad to see a proper attempt to quantify the benefits of the spacer. I was hoping for more test results, more than just seat of the pants.
you know how much car guys love magical bolt on hp gains with out any data!
TB spacer helped move my TB to a more desired location. That's about it though. Just pulled it forward a bit.
next you should do are twin turbos worth it or not
Ha, that would be good.
Bro you need a fucking life....
Anthony Smith Jim
Depends, twins turbs spool faster, but requires more maintenance, useless for low boost cars, stick with the singles.
The "start it up and see what happens" activity can get exciting. Way back in the mid 80's I was working at a BMW Dealer. For some reason I had to pull off the air inlet to the throttle body (733i). It was an easy job and I decided to go to the restroom before pulling the car out. While in the restroom I here all this commotion in the shop,out I go. I find that the Service Advisor decided to pull the car out for me,wrong. I had put one of the big clamps on up side down and it prevented the throttle from closing, in fact it held it full open. Close call but we all went home that day.
+Dan R wow. Glad it all worked out OK.
I have a deer Whistler on front of my grill.
I have a Tacoma 2004.. I added a throttle body spacer and cold air intake.. I was getting 11.4mpg now I’m getting 14.9mpg.. it really did improve my gas mileage
Thats great!
You got a 3.5 mile-per-gallon increase with just a TBS and a CAI !??
NAH. Mebbe you don't figure your gas mileage properly.
If that were even POSSIBLE, Mr. Toyota would have put them on all their cars & trucks -- like YESTERDAY !!
Put one on my 2017 Ram 1500 with 5.7 Hemi. Totally robbed the low end torque. Caused the Economy light to stay on no matter how heavy I was in the throttle.
Took it back off and viola power was restored.
It was installed correctly as I have done quite a few. O-ring up and alignment pins lined up with no vacuum leaks.
Why is there a resonator in a performance vid?
Because there's no performance increases by taking off the resonator....believe it or not.
If you do get a check engine light it's because you didn't reset the ECU and then drive it until it relearns all the shift points and fuel trim calculations. only then will you know if it feels the same way it did before
As A Auto Diesel Mech 35 years I have watch people put cold air intakes and spacers all kinds of junk and a lot of them do nothing to increase power.Cold air Intakes are the biggest joke Unless you are pulling the air out of a Ram air Duct through the hood and force feeding a large Volume of cool air there will be a lose of power.For all those that are in question I recommend that you do this. Ask to see a Dyno test on the vehicle you are planning to modify not any other vehicle but the car you are making the modification to.Also you want Before and after tests of any performace part under the same exact conditions including air intake temperature.This is one of the first steps for tuning a car.Next have your car dyno tested for a base line. Then when you are done with your changes have your car dyno tested and tuned if needed this will confirm you gain anything.This video is in no way proving this spacer works.Also no word of mouth even from trusted friends THE DYNO DOES NOT LIE.
I would disagree on most cold air intakes... Technically most aren't "cold air" because they sit in the engine bay OPEN to the heat, but SOME do come with heat shields and are mounted in bumpers etc. You do get an increase in HP and Torque because the stock (for most) are highly restrictive. Speaking from experience, my S10 had a box with a flat filter that was fed by a 3" opening into the box. I changed it to an AEM cold air intake and my throttle response and torque went up noticeably. No dyno numbers because I don't have that kind of time. But it does work.
DeFreshS10 First let me say I not trying to offend you but the increase in power that you think you felt is not detectable by any human being you would need a min of 50 HP before you would be able to notice a change .A 5-25 HP INCREASE can only be measured by a dyno or running down a track with times AND THE KEY IS SAME EXACT CONDITIONS.What I will say if you notice any change in your vehicle it would be in fuel economy if you were checking it from the beginning.So with This said it would of been mainly from going from a paper air filter to a cotton air filter this is were you increase of power would come from.As for cold air tubing this is a restriction by design Any vehicle pulls a given CUBIC FOOT A MINUTE (CFM) so Cold air induction has two flaws,First being in order to get the coolest air into the engine means we have to go out in front of the radiator.So when we make just one 90 deg bend we need to 6 feet of straight tubing to regain laminar flow.So now we move to the short design which means our air intake is right next to the radiator and we pick up the heat from under the hood.I prefer a ram air system into a short run the benefits I pick up is I get a pressure increase as the vehicle accelerates. second if I am racing there old school tricks to cool that air down further and correct the flow of air.Also I do not pick up ambient heat from the radiator or engine compartment as a ram air is truly sealed.What are your thoughts.
I would PATENTLY disagree with your claim of not being able to "feel" anything under 50HP. My stock motor has ~170 HP... and that a 10hp gain would be a 6% gain in power. Not only that, you INCREASE the power at low end RPM range. Now a CAI on a motor with ~250+ would be insignificant and you most likely wouldn't feel it. *"What I will say if you notice any change in your vehicle it would be in fuel economy if you were checking it from the beginning"* yes. there was an Increase in MPG, though only about 1.5 or so. But I could still feel the difference in low end power. The amount of air going into the engine is measured. If your ECU recognized more air, it could dump more fuel (provided you have a tune). My intake pipe was actually larger than stock and longer (regaining laminar flow) so CFM increases.
DeFreshS10 DeFreshS10 Again I would disagree with even a on any engine in horsepower gains not even the pros can feel a 10 HP gain.The only way to see a increase is through time.If you take a 10 hp engine and loaded it down until it stalled you would see that it is a small amount of power. Now if you are talking B/TORQUE Then you might just might feel a difference.As far as a longer larger CAI TUBE you lose efficiency and laminar flow as there tends to be more bends in the pipe.I have had this debate with others and like I said if all things be equal the proof is on the dyno.I deal with engineers from JOHNSON MATTHEY,CCC , CUMMINS, GM FORD ETC ALL telling us how great there equipment is yntil we prove or dis prove it on a Class 8 emmission laboratory DYNOMETER.
peak HP can be the exact same for both stock and CAI engines, yet you can still feel a difference. Can you tell me why?
I put on on my f350 v12 and I got an extra 50mpg to the tank. Helped out alot considering i had a 6inch lift and 33in tires.
Why don’t manufacturers just make their tb “longer” if it really works.
Because it’s a waste
They make the intake shorter or longer for different purposes, both changes the Charakteristik of hp and torgue thats why some have a changeable intake like Dodge 392 engines
Easy upgrade would be replacing the resonator with some pipe. Smooths the airflow and cleans up engine bay appearance.
I thought about that
Yes there's a nice aggressive tone on mine as well under wide open throttle. The Bullydog Platinum GT just enhanced that with even better throttle response on the premium tune but didn't see any difference in MPG yet
I mean, if you added a cold air intake, larger throttle body, and a full exhaust system, it may be good to slap this thing on for a little extra performance.🤷🏻♂️
Omg you guys 3 extra horse power is killin em on the drag strip
Horsepower is horsepower, idk what the issue is 🤷♂️
Thanks for the video. A longer pcv tube which generates more volume at the throttle, should produce the same effect.
great video, thanks for sharing information about throttle body spacers.
I have a 2006 Chevy trailblazer in-line 6 4.2 vorthec I got an air raid worth 126 dollars, it was worth the money I have no intake just stock and yes when you come out from a complete stop I goes much faster way faster, and yes it makes a little whistle like turbo , the only bad thing is the spacers that comes with the package they are not good they strip and sucks so I took them off but yes it’s worth it
There is a video posted titled "par Honda Accord - throttle body spacer dyno" this is a before and after dyno on a fuel injected Honda Accord.
Results WOT were 3-4 horsepower and 7-8 ft lbs torque. He also tested mid range power on the dyno and made an overall 5 hp / 5 ft lbs of torque.
That makes it at best (on the Honda) $20-$25 per pony.
Now the debate is that output on a dyno can vary. Was the slight gain from the tbs or was it an environmental factor like temperature humidity ect.
dasllamas, I agree with your thoughts on how Darkness can vary each pool. Hard to say at the spacer made a difference but they do sound really awesome with that whistle sound!
dasllamas do you have a Throttle Body Spacer on your Charger?
What ever, if their was a hp gain, it certainly wasn't from a throttle body spacer.
Tell me a reason why honda didn't put it by the factory?
Billblackeye there are many parts that are better for your car. They do It because of price. Production cars are literally done so if they can save a dollar a car they will because after they sell a million cars they saved a million dollars.
On a Carbourated or Throttle Body Injection fuel system, they ABSOLUTELY make a difference in power because it actually causes the fuel and air to mix much better.
Modern cars are multiport or direct injection, so the fuel mixture does not pass through the spacer at all and does not get better mixed into the air.
The only way it could make a difference on a modern car would be by increasing the intake volume... but not by much.
my thoughts:
if you want to do everything, or you are already going to have everything apart, then this is something to do, BUT it's not worth it to do it on it's own....
It would be a good idea to add on when taking off your TB and cleaning it.
It showed improvement because it did a throttle body relearn. Everytime I do a throttle body reset on my Ram hemi it becomes more responsive until the ecu learns and does it's programming.
All it really does is increase the DISTANCE the air travels to get into the engine and creates a slight restriction in airflow. By doing this though, you increase air velocity so at low rpm you might gain some slight low end tq but it is quickly negated as the rpms rise and actually hurts horsepower because now the air is traveling farther and is more restricted.
Tyler Phelps 🤔🤔🤔
Or vise versa
This is kinda wrong, the spacer would increase the plenum behind the TB area there for the "restriction" wouldn't be an issue since these engines don't consume the plenum area that quick (which is where the cylinder is directly pulling air from). You also wouldn't see any more low end torque but rather an increase in throttle response because the air would be moving from the tb to the intake valve quicker. Which is the take away from this, power gains aren't there unless the fuel flows through it too, but it will have a very slight difference in throttle response.
Maybe on startup the air takes a tad bit slower to reach the chamber, causing a bit slower startup, depending on the spacer size. But air is a gas, which is an unlimited source, and is consistently flowing into the combustion chamber after startup, granted the filter, throttle body, and engine is working properly. I personally don't use throttle body spacers or plenum spacers that's over a 1/4 inch, in conjunction with other parts. The only thing these parts improve when used by themselves is throttle response. Horsepower and torque gains are a hit and miss.
If this were a carb spacer then yes, it is a definite upgrade. A carb spacer allows both fuel and air to pass which usually increases torque fairly well with little gains to actual HP. This application however, being fuel injected only passes air, half of what is needed for substantial gains if any. I would venture to say at best maybe 1/2 HP and 1-2 more torque, but I kind of have my doubts of any real gains.
For $100 and easy install, 1-2 hp and a nice little torque upgrade aint bad at all.
i polished the inside of the gas tank and now the fuel flows faster so then more fuel =s more horse power.
Had a TBS on my 03 gmc sierra 5.3l vortec and i loved mine, it did make a whistle noise that was very audible, i liked it though, between the Aftermarket intake system making a audible sucking noise mixed with a whistle from the TBS it gave the motor a more performance built sound to it, it did seem to add maybe 1mpg on the truck, but its a cheap little part to help improve throttle response if you buy the spacer kits that actually are grooved like a gun barrel so it works to "speed up" the induction and increases the total air took in while making it mix with the fuel more rapidly and easier. If your spacer is a block of metal, its wrong, if your CIA is not in a box that is ported to take in air from the outer edge of the engine bay you have a hot air intake not a cold air intake. my 5.3l vortec had an AFE CIA with my TBS (forgot brand) and i ran a bullydog tripple gt tuner on it and i pulled away from other gas burners off the line and held it, when i had my 40l6e built by Jasper that had a heavy shift kit, 16 kevlar clutches instead of the stock like 4-6 it has, high volume oil capacity and high fluid flow kit with trans cooler, better valve body and planetary gear, it cost me around $4,000 total in labor and parts using my own Core, it became a shit show when racing, walking them constantly. IF your gonnna buy parts BUY CORRECT AND QUALITY
You really didn't put any comparison data into this test. How it feels to you means nothing really
J Bouchard a
J Bouchard it sort of does because street racing is illegal, No professional would be watching this and you don't really need it. Altering the volume of your intake is for going faster than 200mph.
When you know your car, you feel the slightest thing happening to it.
Guy just installed and tested it. What about you ?
Daëmon I'm sure that it does something. It increases the volume of your intake. I'm sure that does something. I don't personally know what it is but I do know that unless you have a finely-tuned stroker Engine with big giant heads on it then it's not going to make that much of a difference. Several things are run on the vacuum inside of your intake. Those might be affected depending on the increase in volume. There will be no vacuum at lower speeds which means certain things in your electronics will work different. Anyting that operates based on the vacuum and your intake will do whatever it does as the vacuum approaches 0 at a sooner time and that is not necessarily a good thing but in a larger engines with more horsepower you might need that because they suck an air way faster and more air. That is the reason that you would need to expand the volume of your intake. But you probably think that you can hear noises and that it means something from an engine that was manufactured to reduce noise and a sideways and not rear wheel drive. I personally pay more attention to what kind of vibration at makes and where it is coming from because I can't hear s*** inside of my car.
4 horsepower and better responses
I have 2005 GMC ENVOY XL 4.2 I used the Airaid throttle body spacer alone with K&N cold air intake & removed both factory mufflers and installed Cherry Bomb 3" inlet outlet glasspack the longest one I could find its Bolt on flange to catalytic converter adding dual tips like on the Dodge challenger soon nxt going to buy the jet performance stage 2 chip
I think you misconfuse intake spacer vs 'plastic' or 'plenum' ones. The real one's supposed to cool down your complete inlet on your engine from being warmed up, so your cold air does'nt get soaked in heat with a hot intake. A spacer in between (for example between block and intake) would drop the air inlet temperature a few degrees producing more HP cause of better ignition. But all these mods are 0.1% increase, you should simply go for a bigger turbo or compressor based on what you flavor is. The thing in this video only shows a threaded intake spacer, which would 'warp' the air a little more providing a little more torque, but nothing serious and proberly lose power on the high-end.
Well I think you confuse what misconfuse means.
KronosSlots you’re right about losing in the high end but I have a AFE throttle body spacer which makes a huge difference at low end, but I do have a full stage 2 cold air intake by AFE which replaces both the resonator and box intake and the combination of the two gives insane throttle response and its dry fuel injection not carburetor
Thanks for your informative thorough video. Was ready to buy spacer and install on my 3.6 Jeep Wrangler. Like you I have a cold air intake and performance exhaust system. Which made my Jeep considerably faster... But being an old Gearhead as I am, We always want more
POWER.. Great video.. Thanks from Chris
I would do a tune before coming to a conclusion, anyways nice video man subbed!
Ya. I like numbers. A visual on what changes and how much.
I have a 04 6.0 Silverado 5 speed with edge programer, and cold air I got 16 mpg, added the throttle body spacer and went up to 19. didn't change my driving or anything.
without dyno numbers this "test" is invalid. You can say it feels different all you want but that could just be the placebo affect.
Effect?
I have one on my truck from American trucks.com. I have a whistle but it’s nice, have cold air intake and full exhaust. Truck is a Silverado 4.8 with headers
it works better if you throw a few bolts into your intake manifold
Or you could pour a 5 lb bag of sugar into your gas tank. Sweetens the gas and makes the engine take it in faster.
I had a Throttle Body Spacer in my Genesis Coupe 3.8 with a side port. It was perfect for injecting Seafoam intake valve cleaner.
Nice presentation, excellent commentary and good job on your mechanic skills...
I'm gonna put a spacer in my 03 tahoe 5.3l vortec to see what happens with low end power thanks for the input on your project .....
Did you?
You can do SO MUCH with the LS engine
I put this on my 06 Silverado 5.3 and drink a 12 pack of cold modelo it worth it doing it
Daniel Barajas 😂
i had one in my truck and the big thing is it can give you more part throttle low end torque then high rpm horse power
Thanks for the video Jeff. I have an '06 Envoy with a 4.2L. I'm trying to find the right combo of parts to get a lot better performance and of course, better gas mileage. I was looking at the Taylor Cable Helix Power Tower PLUS Throttle Body Spacer. It's a little pricey at $115, but with an AeroTurbine muffler (which I know works) since I already have 3" pipes, a decent cold air kit, and a Jet Stage II Power Module, I think I'm going to be in pretty good shape. What are your thoughts on this combo??? What are your thoughts on boring the throttle body?
+Robert Robinson I'm not familiar with boring the throttle body so I can't offer any insight on that. If you have good experiences with that muffler then you should be OK. I recommend the K&N cold air kit.

Well, Bob, I have bought, installed, and tested the Taylor "Power Tower" and also a "Power Module", and BOTH of them are over-priced and completely worthless on my Port-type, Fuel Injected, V-8 engine.
Those "power modules" and high-performance "chips" are a total SCAM -- there is NO CHIP inside, just a small resistor that tricks the computer into thinking that the intake air is colder than it actually is, so it adds more fuel.
It's a dumb-ass idea, because your computer adjusts the Air/Fuel ratio , according to the signals from the O2 sensors.
Clever advertising and a lack of oversight allows companies to exaggerate their claims, or even LIE to their potential customers -- it's capitalism - the American way !!
just a heads up what you have is not a cold air intake. the coldest air is in front of the radiator
Without a dyno before and after, you wasted your money and our time
lol, five and a half minutes of your life are that crucial.
hojo70 Why would it matter? You already sound like the type that even if he did get a dyno you'd still not believe it. There's plenty of forums showing dyno proofed TBS. UTFSE noob
Logan P Don’t even waste your time on this nutsack
Doing a dyno twice is a waste of money and time
I've been installing these things paired with K&N intake kits for years and i heard mixed reviews from my customers, they say either it does nothing at all or it improved fuel economy. I personally wouldnt waste my money on one
+808 Tait thanks for the feedback. After using it for a while, I would probably agree for my application.
anyone that needs to hire someone to install a throttle body spacer is in my opinion in NO POSITION to judge the performance gains or losses from one.
@@THE_CHOAS_ENGINE FACT'S
if you want better performance then get rid of that stupid intake resonator.
Hahahaha so true tho lmao
Does he not see he has enough room on that intake tube to directly connect to the throttle body?
U want better performance get rid of that truck😂
@@deneroblack6833 facts😭
I have the same truck and im about to order the same part, thank you. Im really tryin to bolt on and do as much as I can with my 4.2L I need more power
Holly crap DAna miller, are you kidding me, 11 to 19mpg, because you put a 1/2" thicker spacer.. Do you think we are all that dumb?The worst part about these companies ripping off people, are those that get suckered so hard into believing the hype, you will argue for the product and get others to take a chance and then waster their money also. How dare You!? Hmm, I feel it in my pants, I don't know anything about engines or how they work, but I know this piece of metal has the power greater than Jesus. Hmm, the factory doesn't use these cause they love paying the government EPA fines for failure to meet gas mileage regulations on every single truck they make. COME ON! Please, just go ask someone who knows how engines work, not just the guy at Jiffy Lube who only changes oil. You need to talk to someone that understands how a motor works and can explain it to you.
