    The results are probably because there was so much airflow during highway driving that it was cooled more with the unrestricted cone. I would think that during idling, the results would skew more towards the stock air box, since the air inside the engine was not being replaced by driving speeds. Thanks for the test!

    If you have a K&N air intake system with the air cone filter exposed make a heat shield plate to prevent it from breathing hot air from the engine area now...it will breath cooler air from the outside! I did that and it works better! 😊

      Stock filter box gathers it's air from in front of the radiator. K&N so called cold air intake filter gathers it's air behind the radiator. Heat shield or not that's not better.

    A lot of the heat picked up in the charge air comes from the intake tubing, between the filter and the throttle body, this is why the street race guys put ice in the intake header, to cool the charge air. You can reduce this heat transfer by wrapping the intake tube with heat wrap but the best results will come from a higher flowing intake like the K&N (yes, I know a lot of folks don't like K&N but you can use other brands) leading into an intercooler.

    I feel as though, Martin, a gutted factory box on most vehicles with possibly a modified ram piped into the box would be superior to a majority of "cai" on the market. And they'd offer a lot of protection to where your engine draws air by design. Great test you did. Your videos are always so practical.

    I know this was an older video but still a Good test. i think the term cold air intake is the selling point. The after market air intakes do flow very well and k&n does a good job engineering them. i would love to see this test done again but with a 3rd type like the volants where they are like a mix of the k&n and factory. A better flowing tube and filter but with an improved air box and lower air intake tube

    If you pull the tube out of the stock air box you can get more air into the engine and the air filter is protected. I pulled the 2 tubes out and I cut the air barrier out of my air box in my Grand Prix. Now I get more air and the air filter is protected. Also engines react differently to SRI, CAI, stock air boxes, and modified air boxes. No engine reacts the same way.

    Awesome you make a prediction then prove yourself wrong and are not too egotistical to admit being wrong. I thought the stock box was going to be cooler air and the K&N would be more air too. As most are saying, that K&N that was installed was not a cold air intake. Most Cold Air intakes go out of the engine bay. That one is a performance intake, much like a short ram which sole intention is just more air.

  • @kingwiththeax6880
    @kingwiththeax6880 ปีที่แล้ว

    If the intake air sensor is in the factory location, it will show the same temperature every time. The factory sensor is located on the aluminum intake header, which is heated by the exhaust manifold. The intake and exhaust are practically in contact with each other. If the sensor was relocated to the throttle body, it may show a greater difference in air temperature entering the throttle body, but it will get warmed to the same temperature as it travels through the hot intake manifold. This is an engine layout that will likely not produce cooler intake air at mixture regardless of the intake piping design. You may see more improvement if you rigged up some DEI heat shielding between the 2 headers, but it won’t stop heat sink from the head, because they are connected to the same metal surface. “Cold air” is false marketing, unless you put some dry ice in the air box.

But you are right CAI AFE GT momentum or stock in closed boxes are best if you get outside air not engine air , but yo still need more oxygen to get more power so more cold air is best.

    The original air intakes are not designed to take in as much than the performance filter. The performance filters stop much more dust particles from entering the engine that actualy damage the engine over time. They stop about 2 parts per million dust from entering your engine and allows the engine to breathe better. These filters are used and tested on formula 1 racing cars. that says a lot to me.

  • @Aikidoman06
    @Aikidoman06 4 ปีที่แล้ว +5

    I never believed the “cold air” part. When a car is moving the hot air is pulled under the car and the outside air pulls in.
    The reason cold air intakes improve performance is because of two factors: The lower vacuum pressure required to move air into the engine, and the efficiency of the air flow. There is no reason to discount these systems, just shouldn’t try to convince people it’s because of cooler air. The air temperature effect would be negligible.
    Thanks for the proof! SCIENCE!

    Regardless of AIT, the one issue i have with K&N filters and the like, the filter requires a like coat of oil, that they sell themselves obviously, over time, that oil coats the components inside the MAF sensor and therefore requires a more periodic cleaning so the engine will run more efficiently versus the OEM paper air filter thats normally used.

    Vent the hood or raise the back by the cowl and remove the weatherstrip at the cowl. That will do more good than a $300 CAI system. The only way to get cooler air in is to get the hot air out. Figure a way to keep the fuel in the rail cooler, that will help a lot more. It is a non return system so the fuel sits in the rails for quite a while and those rails get HOT! I replaced my standard 4.7 air intake system with one from an HO, has a better flowing resonator box, larger dia round tube vs oval and a larger air box. Modified the fuel rails so each side gets fed fuel vs getting fed on only one side, keeps the fuel cooler, and raised the back of my hood with a couple washers and removed the cowl seal. It did make a difference I could feel, the amount of heat coming out of the gap, which is hardly noticeable, is unbelievable.

    I believe the nomenclature of CAI is outdated. Recall once upon a time the air filter was in a can over the engine, with the carburetor underneath. It drew in hot engine air. But auto manufacturers have long since made it into a cold/ambient air setup. They just designed them with baffling to make the interior quiet (recall TV commercials touting that as a feature of the model). The CAI systems of today are still CAI relative to the old can, but also high flow in regards to the ductwork and filter itself.

    Pods are for ricers and kids and granted back in the late 90's they did work well on the Supras etc. They wont anything good for modern cars if you want the same effect while maintaining your warranty etc then just replace the pipe going from the TB to the MAF Sensor. Its in there that the factory put intake mufflers and restrictive sound deadening materials. Replace it with 3' for V6 and 4" for the V8's. Only then will you notice that the fly by wire throttle lag
    esponse time will be eliminated. Forget pods here in Australia we fit the OTR's now on real cars and then tune the car at the same time. its not unusual to see +30kw improvement at the flywheel. So, to recap POD filters = Clueless owner and a voided warranty at best. Always keep your OEM parts. for servicing and resale. Offer the other bits after the main sale has been finalized.

    What was the temperature with the stock box at idle? I think there may be more difference when the vehicle is not moving, as hot air builds up in the engine bay.

      I actually noticed a substantial difference on my 2004 wj 4.7 ho. Pulls harder in the upper rev range. These intakes are proven through dyno testing to increase horsepower. Obviously 15 horspower isnt crazy as far as gains go, but every little bit counts.

    Have you had a chance to measure fuel economy with the stock air box and the Air Raid intake tube? Just purchased one for my 06 Dakota to see if it helps and to simplify the intake system. People seem to be on both sides of the fence so would appreciate a definitive answer.

    • @martinbuilt
      @martinbuilt  5 ปีที่แล้ว +1

      I can't say I saw a noticeable increase in fuel mileage. I think if you were to get a MPG increase it would be marginal. Sorry if it isn't exactly definitive answer.

      @vr4787 5 ปีที่แล้ว

      martinbuilt no problem, been having issues with the engine stalling in stop and go traffic, slow moving traffic when air flow isn’t constant or optimum so that’s why I went with the Intake tube. Just installed it today and so far no complaints or issues and engine seems to be breathing better.

  • @801russc
    @801russc 5 ปีที่แล้ว

    The reason you didn't see a difference in air temps is because, if I'm thinking right your air intake temp sensor is located right in the top of your intake manifold, although I don't think you'll see a positive anything with an open filter.

  • @willh6838
    @willh6838 3 ปีที่แล้ว

    So... The CAI in isolation vs the OEMI alone is of no significant value in terms of temperature. However, the air flow between them could be different. If the flow is significantly higher with the CAI then the net effect is cooler air through the CAI.

    Didn't read all the comments but did you notice that your battery temp went up 6* on the second run? Just wondering if the ambient temperature went up also meaning the factory setup is actually cooler.

      when I did the test there was virtually no difference in ambient temperature. and I took the vehicle on a good long cruise each time to let the underhood temperature equalize as much as possible

    • @koryyyy
      @koryyyy 7 ปีที่แล้ว

      The battery temp sensor is on the BASE of the battery, so no external air will change the battery temperature so far. The temperature change on the battery is mostly because of a high charge rate.

  • @Chris-bh5pq

    ..Maybe consider re-routing the filter on the intake out of the engine bay. Even with the CAI your too close to the motor.

  • @robdefire4747
    @robdefire4747 2 ปีที่แล้ว

    Interesting test. It would have been interesting to see if the stock airbox that sits on the motor heat soaks more than the airaid pipe. I would like that type of Airaid pipe as I want to keep the stock airfilter housing as its used for offroad half of the time. The stock filter looks to better coping with water crossing. I never go deep enough to have the inlet under water but it does drain well. I like your through the bonnet CAI but worry about if I do get water over the bonnet, its going right in the motor. I have removed the rear bonnet seal which should work like vents in the bonnet to get temps down. I would like to try an Airaid pipe but heat wrap it and maybe heat wrap the filter housing. Then again Im probably overthinking it.

  • @thatotakubear1150
    @thatotakubear1150 5 ปีที่แล้ว

    This simply DISPROVES the myth that these intakes are worse for your car. You pull in more air( larger area filter and smoother tube) with less restriction and you don't run hotter temps. People don't get that these DO NOT remove the factory air inlets i.e under ther bumper or wheel well, they simply remove the plastic box (which has zero thermal insulation).

  • @TheDiamonddust1

    I live in the south and use my truck on the farm and for hunting and such so I would rather go with the sealed intake box and the Airaid jr intake pipe . If I were to run that open cone filter it would be sucking in water and dirt without a doubt I have been in situations where water and mud were rolling on my hood more then one not playing or trying just situations I run into on the farm and hunting property .

  • @mkedan6741

    You really have to get educated before you bolt something to your engine that could shorten its life. Take it from someone who has been doing this since the late 1970s. Most of any gains from CAI(and this isn't), and those are minimal, come from low restriction filter elements. The problem here is, are you willing to give up engine life for 5-10 horsepower on your 5000 lbs. vehicle. You could get the same performance gain by removing that flat 75lbs. spare sitting underneath. Modern engine design and competition has pushed manufacturers to squeeze every bit of performance while staying within guidelines of emissions, noise factors(intake and exhaust), applications, ect. Ford isn't going to be able to sell a truck with a 5.7 liter engine if Ram has a 5.7 with 50 more horsepower and 100 ft. lbs. of torque. If you want to boost real performance, you need to look at a complete package. That will include intake, exhaust, camshaft, cylinder head, trans work, gearing and tuning this to make it all work as a package. Bolt the stock airbox back on and get a quality filter like Wix, change it every 10-15k miles and thank me later.

    Hi Martin. good video. Thanks. Answered one important question [AIR TEMP] but an equally important question remains and that is the difference in INTAKE ('INLET' here in Australia) AIR VOLUME between the two air filter element types [FLAT vs CONICAL]? It would require a dyno but interesting, eh? Ultimately it is determined by Throttle-body diameter/blade area etc but it would be cool to know as well. Anyway, how have you been mate?

    There are some supercars that actually run the air conditioner system into the air intake So to boost the horsepower obviously the colder the air the better So by routing the box to the coldest air outside the car would be best instead of across the radiator heat lol

    That seemed like a CAI with a Short Ram Intake setup. There was no heat shield or anything to isolate engine bay air.

    @levimaynard2237 7 ปีที่แล้ว

    If the IAT is located where the older 4.7's is (directly to the intake manifold), then you wont really see much difference no matter what, as it is reading air after it has already passed through the throttle body and the upper intake manifold... Relocate the IAT sensor to the intake tube near the filter and then redo all this.... then you may see some different results.

    • @shabutir1820
      @shabutir1820 7 ปีที่แล้ว +1

      Levi Maynard Why would that matter though? No one cares what the air temperature is before it enters the engine. Having colder air outside of the throttle body wont have any effect on your engine performance.
      What matters is the air temperature once its inside the combustion chamber.

    • @levimaynard2237
      @levimaynard2237 7 ปีที่แล้ว

      The video clearly is trying to test air intake temperature... You are trying to call me out for something the video is clearly doing? The creator of the video cares, that was the whole premise of the fucking video. The video is testing if the "cold air intake" has a lower temp than the stock airbox. Both of those pieces are (OBVIOUSLY) in front of the throttle body WAY before the combustion chamber... There is NO sensor to test the air temps in the combustion chamber, on ANY vehicle. The IAT (intake air temp sensor) is what the reading is coming from, not the combustion chamber. The IAT is mounted directly to the Intake manifold on these. The heat created by the engine running, ambient temps under the hood, spread throughout the thin plastic intake manifold and make the temps higher, so no matter what you do, you are getting hotter air readings than the air that is flowing through the "cold air intake" as well as the stock airbox. Using YOUR logic, having colder weather and colder air coming in has NO effect on engine performance..... Really? The entire premise of this video is flawed because the IAT is in a significantly hotter area than the air intakes.

    • @shabutir1820
      @shabutir1820 7 ปีที่แล้ว +1

      Levi Maynard I agree.
      What I was trying to say is that cold air intakes are useless. All stock intakes are cold air intakes technically. As long as your pulling air from outside of the engine bay (like all modern stock intakes do) then you have cold air intake.
      Also, Im aware no car measures air temperature inside the combustion chamber. Im also not saying colder air wont impact performance. Im saying that you want colder air inside your engine. Having colder air outside of your engine will not help you as far as performance goes. Keeping that air cold until it gets into the engine is where real performance gains are seen.

      I know the first hell cats had an AC line run into the intake that you could use to make horse power . I think it worked by running the ac to get the unit cold and then you turn the ac off and open the vent to the intake to save power and letting the cold air left in the unit flow into the intake . Say what you want but for a street legal factory car dodge looked at every angle to make horse power and they have truly lived up to their nick name The House of Muscle .

      It was a huge difference. It comes in at the same as ambient temperature. The one thing I did notice though once the vehicle is warmed up and you park it when you return to the vehicle ( let's say after an hour or less) the temperature is significantly higher than ambient. And stays above ambient temperature.
