Great video and shows what benefits there are of the K&N filters. I honestly do not know why people bad mouth them so much. I have used them for years in multiple vehicles and never had an issue. Just got one for my new truck to replace the stock filter that was in it.
Thanks man!🤙 They definitely aren’t bad filters and the dyno doesn’t lie. I think most of the bad mouthing has to do with the quality of filtering offered by K&N filters.
i would agree, i’ve used them for years and always found them to be a great filter, i think some people just don’t wash and oil them correctly which will cause bad filtering, if oiled correctly they filter just as good as paper
@@DroneStrike1776 even without project farm, common sense tells us that these filter flow Kore becouse they are less restrictive and that restrictions the filters going on.
I recently replaced my paper air filter with a K&N one, and it woke up my 2014 Police Interceptor Utility. Much more responsive, and ever so slightly better gas mileage. Word of advice! Never oil your K&N filter, it will destroy your MAF sensor. Just take it out, and clean it with 99% alcohol, and a spray bottle. It’ll get most of the crud off of it. And let it dry afterwards, since alcohol is very flammable lol.
I just remember in the past with my 1993 G20 conversation van 5.7 going up a hill losing power doing like 55mph with a paper filter, then a k&n on the same hill and a decently loudish WOOOOOing sound not losing any power. Getting of at the exit on the same road from being in Overdrive with the paper filter... OOPS, give it the gas vehicle cuts OFF at the traffic light that just turned green! Same road OOPS left it in Overdrive Again WOOOOOOO! LOTS of power! Those conversion van filters small! The 6.2diesel filter in the same g20 van was much bigger🤷🏻♂️
KN is a great filter. However, Most people don’t close the filter box cover properly. Just put one on my 2022 Highlander. It awoke the beast and corrected cold trans operation issues. More pleats and not thinner filter element material is the secret.
I’m using K&N drop-in air filters for a year now. The immediate benefit I observed was the cleaner airbox with the K&N. Using the OEM filters, it still allowed some dust through the filter and leaves a very very thin layer of dust on the, supposedly, clean side of the filter and airbox near the MAF sensor. Now, I know that with the K&N filter, clean air will be go through my engine. Everything else like increase in engine output and better fuel mileage is already cherry-on-top.
I bought a K&N air filter for my 2019 Mazda3 awd hatchback after watching this video a few months ago. 186/186 HP and TQ stock is pretty sad. Mazda took a 2.5L at 13:1 CR and made it into an economy car running 87 octane instead of making it into a little NA ripper. The car is so insulated that I couldn't hear the induction with the OEM filter. K&N gave it some needed induction sound. If my car is making an extra 5whp in a car that weights under 3200lbs with AWD, I'll take it. With the K&N and 93 octane without a tune, read an article with dyno numbers that the Skyactiv is capable of self learning and adjusting for 93 octane, the car is pulling more at the top end without pulling timing like it did on 87 octane.
I have run a K&N filter in my 2006 Silverado 5.3l with 170k never had a single issue. I clean and re-oil once a year. Unless you drown it in oil there should be no MAF issues.

Great video and very informative!! I wish more people compared air filters. I didn't expect that with no air filter. My advice after watching 'Project Farm' testing 6 different filters, including K and N is to use paper because it catches way more debris than K and N, and K and N tends to cause problems with the intake sensor due to the oil from what Scotty Kilmer says. The few horsepower isn't worth it unless you're on a track. Wix did best on Project Farm and second best was that Purolator One you had. I just put a Wix in my 2013 Lexus RX350 and a Wix XP cabin air filter also. The Wix also did well in Project Farm's 0 60 test.

Going from 150 to 155 HP with an air filter change is a good deal, also the fuel economy will be better with a free flowing air filter....that fuel $$$ economy change would be a good test.

Adam Mossinghoff Thanks! I know it’s going to be a bit pricey and a pain bolting and unbolting heathers. But I’m with ya! I want to test them and finally settle the debate once and for all!
Any comparison to the competition? Like PRL, BMC, Spectre, Green filter, AFE, AEM, HKS, DNA, kak... would love for someone to do a real showdown between all the filter
I didn’t do any comparisons. However, there used to be a study publish somewhere where someone actually bench tested all of the filters I want to say green filter did the best of the performance filters. But ultimately a standard paper filter had the best air flow when it started to load up with dirt.
Would be interesting to do a test on regular oil vs synthetic oils as well as additives like Motorkote,Bestline,Lucas etc to see if added to oil if they add horsepower or not.I know they quiet the engine and help with a barrier of lubricant on metal parts to reduce friction.
Bill Lunebach So if you are interested in tests like that. The Farm Project is a TH-cam channel you need to watch. The guy has tested just about every oil and oil additive. Check him out and thanks for watching!🤙
Back to back runs without any cool down time affects the runs results negatively. Considering you didn’t do all test at the engines coolest points. Actual negatively affecting results as engine heats up back to back. Reason people change the radiators to keep the engine running cooler for longer periods for best performance.
What I didn't show on the video were the cool down periods. Basically, we would let the truck idle and then turn the engine off. A large barn fan was setup in front of the radiator to increase cooling airflow. The dyno I used was run by a highly reputable guy in the area.
God Speed I’ve read at least one flow test that showed K&N doesn’t filter as well as a paper filter. If you have read otherwise, link it here in the comments. I like to be up to date on automotive tech studies.
DEATHMETALDUDE 666 I definitely should! I’ve had the K&N filter on my truck since this test without oiling it. I should do a video comparing it to the paper filter after running paper the same amount of time.
MrBlaze256 I wish I had saved the link a while ago but some guy did test the filtering abilities of several filters including K&N. Paper is the best filter and also flows more air when dirty. K&N has the lease amount of filtering and when clogged flowed the least.
But does the K&N filter have the same level of filtration? Is there a cost of worse filtration which leads to more wear and tear on the engine for more horsepower?
It has been tested and the K&N filter does not filter as well as a paper filter. It also becomes less efficient as it fills with dirt when compared to paper.
Scrum Thebum2 It does! However, I removed the extra intake piping the goes from the air box to the hood gap. Deleting that makes the intake sound louder with a stock paper filter.
What’s your 02 sensor saying with no filter, I’ll bet the fuel trim is running lean and that’s why you’re losing power… Probably need to tune it for that much increase in flow…
It’s an OBD1 truck. So I don’t have that read out. I would agree there needs to be some tuning to make the CAI work. However, K&N never instructs the end user to get his engine tuned. In my case, you can’t tune OBD1 without adding extra tune able components to the ECU.
bax442 So that’s a at the wheel horsepower number. The 5 liter engine is supposed to have 190-200 hp at the crank. When you factor in drive train lose, then you get roughly 160 hp.
@@TheMinuteMasters I hope so! Not saying to make you feel bad, but it feels like FORD did not know what an engine is. BMW were getting 160 from 1.8l engines 25 years ago :)
bax442 I think most American car manufacturers had large displacement engines with very little horse power. The Pontiac Firebird from the 80s had a 6 liter V8 and it only made around 170-180 hp. Now the different for trucks is the torque. I have almost 70 pound ft of torque than horsepower. Cars are usual equal torque and hp or more hp than torque. I guess you could say torque was more important for a truck than hp. Either way, they definitely could have improved the hp number. Lol
Is it a good idea to run a cold intake on a stock 97' Jeep xj ? I heard it wears dwn the engine? Any truth to that? They said to put the original back on...
I don’t think it’s worth running them unless you are a professional racer who tears down the engine after a few races. They do let more dirt into the intake which in theory wears the engine down.
I tested the K&N CAI and the results were terrible for this year of truck. Furthermore, although it is advertised as a cold air intake it’s situated in such a way that all it does is suck hot air from the engine bay. The stock air intake is the coldest air intake in existence.
The paper filter is the best a filtering. I read a study by one guy and he tested a few performances filters against the oem paper filter. The paper filter filtered the most dirt as measure in microns than any of the others. I’m addition to have the best flow when clogged. Once the K&N clogged it performance worse than a paper filter.
bris fry We let the truck and engine bay cool off for 10 minutes in between each run. So engine off with a 4 foot diameter fan and an air mover pushing cool air through the engine bay.
Nithin Jacob Ah yes, you could do that. However, the test showed actually having a filter helps. If that’s do too air turbulence and such. Then you could design a straight pipe method that simulates it.
starent veveo So the dyno tech told me that turbo charged engine’s see the most horsepower gain with cane and filters and cold air intakes. (50 hp gain on the new stingray corvettes) This is mostly because the turbo charger can’t suck enough air in through the stock filters. I’d say go for it, but make sure it doesn’t void any warranties.
@@TheMinuteMasters Dirty MAF / MASS sensor = rich or lean conditions due to inaccurate readings which can lead to misfire condition. Dirt in cylinder wore out piston skirt, cylinder wall and rings enough to create some knock in one of my vehicles. Still ran well but could not revv very high. I believe it was cylinder 1.
I think one disadvantage of stock paper filter compared to washable air filters is this, possibility of paper filter to be sucked in by your turbo during high boost? anyone experienced it?
TH-cam User Yeah K&N are just plain dirty and that’s the trade off. Sweet! I’m going to check out aFe when I get a chance but do they make a oem filter for the truck in my video or are you using it on a different truck?
@@TheMinuteMasters Great post though and appreciate the effort, just with aviation and having to manual adjust mixture a leak in the intake will do the same thing and not in a good way...
@@TheMinuteMasters That happens more often than not. Just go back when you can and complete in one time period and can be done in a few months. Best of luck with getting back in the saddle...
Makes no sense to me, the air filter is not about power, it’s about cleaning the air intake and preventing damage to the engine. So that k&n makes 5bhp interests me only relative to whether they protect the engine long term as well as the paper filter.
these numbers are very close to reality, there is no big gain until you change the camshaft, some characters faked the numbers on dodge, they got at least 20whp with the filter......
I read an article a year ago. They tested a K&N filter and a paper filter. By far, the paper filter captures the most particles. K&N filters are known for letting particles through and coating the sensor wire in a MAF and causing issues.
@@TheMinuteMasters I actually looked into K&N filters the other day when i noticed you can actually see holes in them when you put them up to the light. I THEN PURCHASED A NEW ONE THINKING MY FILTER WAS JUST OLD AND THE NEW ONE WAS THE SAME. IT WAS THE SAME. NEVER WOULD I BUY THESE AGAIN
@@timm1807 You are exactly right! The added airflow performance comes at a cost. People never consider that and the manufacturer doesn’t explain it either. Paper is the best filter on the market.
More air more gas , k&n is for those people like to press Their paddle hard to get performance , if you are a cruise kinda driver go for paper air filter keep your vehicle runs smooth on the highway and good gas mileage
removing air filter gives you more power only when your moving on streets creating wind ramming .car sitting in a shop even with fan isnt the same thing.

Don't deviate from the manufacturer's specs to try to gain some cheap hp. Remember anytime you do something to gain hp, you impact performance or the life of your vehicle. Filters are supposed to filter air.... and provide clean air to the motor. These aftermarket filters that claim they increase hp don't filter the air as well as the manufacturer's paper type. And many use an oil to attract the dust and dirt because the mesh is not as dense. So you always end up under oiling, over oiling, or not oiling enough. You think you're saving money by buying a washable filter, but the cleaner and oil costs around $50 and you need to do it every 6months or so. Not to mention, the Vehicle's ECU is preset for a certain fuel air ratio, so you're achieving nothing. I'd go oem every day of the week!
I agree 100%! I ran this test just to show what possible gains can be had with these filters. Most agree 5 hp is low enough to be within error territory. Plus these filters cause all kinds of issues on MAF sensors.
@@TheMinuteMasters thanks for your response, and yeah you're right about the sensors. There may be some aftermarket washable filters that filter as well as the oem, but then you're not gaining anything in hp and just paying an exuberant price for a filter. Lol. Everyone thinks it's because the oem is trying to make money, but the ecu settings are designed for that filter, not high flow. Have you thought about a follow up video to test the filtration quality of K&N vs Paper?
@@funcool32 No problem man!🤙 Exactly! Most performance parts don’t work on stock vehicles. Modified and tuned vehicles is a totally different story. I haven’t. I guess I could put a secondary filter in the intake to measure/show the dirt that gets through the K&N filter.
3:30 NO! Air filter can't modify the air flow as modifying it to pass the rest of the induction ducts... I am sorry but you need a crash course of fluid mechanics and physics to understand how wrong was what you said. It's a restriction, a known restriction (ecu) which adds to how the fuel mix is controlled later on the injection. An old carb round filter could, maybe, but no it's just a restriction... And with out it the low and high mix adjustments would require change, to later adjust when putting back the filter. Good experiment on the dyno, but it is one of thousands already done since the 1800's... Well minus a modern dyno of course
I don’t pretend to be a scientist. I just regurgitate what K&N advertises and what floats around the internet. The ECU definitely is a restriction that is not correctable without modifying it. My video is to show case this product in plug and play manner as advertised.
With out tuning the system of the car to actually require more air volume... Any intake mods, including a better filter, ARE USELESS OR EVEN COUNTERPRODUCTIVE No better fuel economy, and no more power... Perhaps even less Same for the exhaust If turbo a better inter cooler (thicker) could actually improve low end power... But then again the system is programmed for that TMIC resistance to flow, so no not even that
I agree 100%! However, OBDI vehicles need to have the ECU removed and modified in order to tune them. That procedure is hardly plug and play which is how K&N advertises their CAI.

Adam Mossinghoff Thanks! I know it’s going to be a bit pricey and a pain bolting and unbolting heathers. But I’m with ya! I want to test them and finally settle the debate once and for all!
Any comparison to the competition? Like PRL, BMC, Spectre, Green filter, AFE, AEM, HKS, DNA, kak... would love for someone to do a real showdown between all the filter
I didn’t do any comparisons. However, there used to be a study publish somewhere where someone actually bench tested all of the filters I want to say green filter did the best of the performance filters. But ultimately a standard paper filter had the best air flow when it started to load up with dirt.
Would be interesting to do a test on regular oil vs synthetic oils as well as additives like Motorkote,Bestline,Lucas etc to see if added to oil if they add horsepower or not.I know they quiet the engine and help with a barrier of lubricant on metal parts to reduce friction.
Bill Lunebach So if you are interested in tests like that. The Farm Project is a TH-cam channel you need to watch. The guy has tested just about every oil and oil additive. Check him out and thanks for watching!🤙
Check out Project Farm on TH-cam, That fellow tests everything.
Changing from normal to full synthetic oil improved my fuel economy enough to easily pay for the extra cost of the full synthetic oil.
Back to back runs without any cool down time affects the runs results negatively. Considering you didn’t do all test at the engines coolest points. Actual negatively affecting results as engine heats up back to back. Reason people change the radiators to keep the engine running cooler for longer periods for best performance.
What I didn't show on the video were the cool down periods. Basically, we would let the truck idle and then turn the engine off. A large barn fan was setup in front of the radiator to increase cooling airflow. The dyno I used was run by a highly reputable guy in the area.
omg what a useful video thank you sir
You’re welcome man!🤙
K&N may allow more power on a Dyno but that's because their filter lets more particulates into the engine
Chris Chesna You are exactly right!
dude that's not true
God Speed I’ve read at least one flow test that showed K&N doesn’t filter as well as a paper filter. If you have read otherwise, link it here in the comments. I like to be up to date on automotive tech studies.
@@TheMinuteMasters look up k&n filter dirt test. the guys channel is motorvate DIY he did test on the engine oil
God Speed Thanks man!🤙 I’ll check it out!
There's no BHP gain honestly but car does accelerate better. It reaches Peak power with little less effort then stock filter.
Nice. I would add that removing the filter may lean out the mixture & lose power.
You are exactly right!
im about to buy k&n filters for my cars since i dont drive in dusty conditions or anything. just normal roads and highways.
Sounds good man!
Excellent job Steve. Very informative video.

Should have cleaned your MAF sensor to while you were there, curious to see if it will really help if there was no issues already
DEATHMETALDUDE 666 I definitely should! I’ve had the K&N filter on my truck since this test without oiling it. I should do a video comparing it to the paper filter after running paper the same amount of time.
i liked it after 3 sec. i wanted to see this test.
Could you also test out differences manufacturer as well?
Like test different paper filters brands?
Removing your air filter completely will mess everything up because you’re changing the air to fuel ratio mix in your engine
Exactly
do a filtration test knn vs oem which one filters dirt the best
MrBlaze256 I wish I had saved the link a while ago but some guy did test the filtering abilities of several filters including K&N. Paper is the best filter and also flows more air when dirty. K&N has the lease amount of filtering and when clogged flowed the least.
th-cam.com/video/uvExyfxzsRo/w-d-xo.html
This video shows how the K&N filters compared to OEM.
But does the K&N filter have the same level of filtration? Is there a cost of worse filtration which leads to more wear and tear on the engine for more horsepower?
It has been tested and the K&N filter does not filter as well as a paper filter. It also becomes less efficient as it fills with dirt when compared to paper.
There fine if you clean them but alot of people don’t. With a paper filter you can clearly see when it’s dirty
True
Truck even sounds much better with theK&N
Scrum Thebum2 It does! However, I removed the extra intake piping the goes from the air box to the hood gap. Deleting that makes the intake sound louder with a stock paper filter.
What’s your 02 sensor saying with no filter, I’ll bet the fuel trim is running lean and that’s why you’re losing power… Probably need to tune it for that much increase in flow…
It’s an OBD1 truck. So I don’t have that read out. I would agree there needs to be some tuning to make the CAI work. However, K&N never instructs the end user to get his engine tuned. In my case, you can’t tune OBD1 without adding extra tune able components to the ECU.
So basically the increase is negligible at best, and absolutely NOT worth the price of the K&N. Thanks for a great comparison.
That just about sums it up. No problem man!🤙
It actually gained power with no filter.
Stock filter 150hp
No filter 152hp
@@scottykilmer3920 what's that green filter?
Very good info.
Gabe Pettinicchio Thanks!
160Hp, does it have 2l engine or smaller?
bax442 So that’s a at the wheel horsepower number. The 5 liter engine is supposed to have 190-200 hp at the crank. When you factor in drive train lose, then you get roughly 160 hp.
@@TheMinuteMasters 5 litter, 40HP per litter? Is that not very very little? :)
bax442 Yeah today’s 5 liter engines produce much more horse power. But mine is 25 years old. Hopefully, I can improve the hp.
@@TheMinuteMasters I hope so!
Not saying to make you feel bad, but it feels like FORD did not know what an engine is. BMW were getting 160 from 1.8l engines 25 years ago :)
bax442 I think most American car manufacturers had large displacement engines with very little horse power. The Pontiac Firebird from the 80s had a 6 liter V8 and it only made around 170-180 hp. Now the different for trucks is the torque. I have almost 70 pound ft of torque than horsepower. Cars are usual equal torque and hp or more hp than torque. I guess you could say torque was more important for a truck than hp. Either way, they definitely could have improved the hp number. Lol
I think you tune for the extra air.
Yes, but K&N doesn’t advise you to do this. They state that you simple bolt this CAI on and that’s it.
Is it a good idea to run a cold intake on a stock 97' Jeep xj ?
I heard it wears dwn the engine? Any truth to that?
They said to put the original back on...
I don’t think it’s worth running them unless you are a professional racer who tears down the engine after a few races. They do let more dirt into the intake which in theory wears the engine down.
Thank you very much!
You’re welcome Mike!🤙 Thanks for watching!
Nice demo
Thanks man!🤙
Even better question tho. Performance cold air intake? Or stock air filter housing?
I tested the K&N CAI and the results were terrible for this year of truck.
Furthermore, although it is advertised as a cold air intake it’s situated in such a way that all it does is suck hot air from the engine bay. The stock air intake is the coldest air intake in existence.
@@TheMinuteMasters true
I want to put one kn filter on my peugeot 207 turbo but i am concerned bout how good it filters dust..
The paper filter is the best a filtering. I read a study by one guy and he tested a few performances filters against the oem paper filter. The paper filter filtered the most dirt as measure in microns than any of the others. I’m addition to have the best flow when clogged. Once the K&N clogged it performance worse than a paper filter.
You might have had heat soak on the third test. Should have waited 30 mins for no filter test.
bris fry We let the truck and engine bay cool off for 10 minutes in between each run. So engine off with a 4 foot diameter fan and an air mover pushing cool air through the engine bay.
@@TheMinuteMasters fair call
Because that engine uses a MAF. The air filter makes the air more uniform so the MAF reads it better.
Randall Schmidt The dyno tech said it straightens the air. Thanks for sharing!🤙 I didn’t know that.
if thats the case how about we remove the air intake box and just conncet directly to the itake with a pipe??
Nithin Jacob Like eliminate the stock air intake piping and delete the filter box?
@@TheMinuteMasters That will make the engine suck hot air. I meant bypassing the filter box with a straight pipe directly from the intake hose
Nithin Jacob Ah yes, you could do that. However, the test showed actually having a filter helps. If that’s do too air turbulence and such. Then you could design a straight pipe method that simulates it.
I have q 2102 cls550 do you think it's worth buying and do u think it will gain more than 5 hp since its turbo chargerd
starent veveo So the dyno tech told me that turbo charged engine’s see the most horsepower gain with cane and filters and cold air intakes. (50 hp gain on the new stingray corvettes) This is mostly because the turbo charger can’t suck enough air in through the stock filters. I’d say go for it, but make sure it doesn’t void any warranties.
From experience,
Early development of misfire conditions with K&N due to extra debris in cylinders. Hard learned lesson. Paper for me.
Jr Carr Really? They fouled your plugs and cylinders you think?
Yup,
One other thing about reusable crappy stuff. Have to oil it. Guess where that mess ends up? MAF sensor. So, yeah, paper for me.
Jr Carr I have heard that. I think the engineers were actually right about this one.
@@TheMinuteMasters
Dirty MAF / MASS sensor = rich or lean conditions due to inaccurate readings which can lead to misfire condition. Dirt in cylinder wore out piston skirt, cylinder wall and rings enough to create some knock in one of my vehicles. Still ran well but could not revv very high. I believe it was cylinder 1.
Jr Carr Damn! It’s crazy how bad they are and every one buys them!
I think one disadvantage of stock paper filter compared to washable air filters is this, possibility of paper filter to be sucked in by your turbo during high boost? anyone experienced it?
I could see that.
Yep happened on my 5.9 Cummins. Looked like it was all wadded up
It's rough about K&N... I get a more aggressive sound from my engine with K&N

Big AL Thanks man!🤙 I definitely wanted science to do the test and not my butt on the seat. Lol
TH-cam User You are right! I need to look into these aFe filters. I keep hearing good things.
TH-cam User Yeah K&N are just plain dirty and that’s the trade off. Sweet! I’m going to check out aFe when I get a chance but do they make a oem filter for the truck in my video or are you using it on a different truck?
Hmm, I think the non-filter would cause a leaner mixture... Thus less power.
I think you are right.
@@TheMinuteMasters Great post though and appreciate the effort, just with aviation and having to manual adjust mixture a leak in the intake will do the same thing and not in a good way...
@@cw5865 Thanks man!🤙 I know exactly what you are talking about. A few years ago I was ready to solo but I moved and got too busy.

@@cw5865 You are definitely right CW! Thanks for the advice!🤙
But you're running lean after swapping the filter
If I remember correctly yes.
Your AFR was showing on the dyno run, and the gains could be attributed to running a half point leaner as opposed to the filter itself.
@@themystx2 This is true. So I’m all reality these K&N products don’t do anything.
Makes no sense to me, the air filter is not about power, it’s about cleaning the air intake and preventing damage to the engine. So that k&n makes 5bhp interests me only relative to whether they protect the engine long term as well as the paper filter.
I agree 100%! +5hp isn’t worth damaging the engine.
And the fact that you can damage your engine should be the #1 reason not to remove your air filter lol
Richard Williams I know right! Lol People will do crazy things to chase “cheap” horsepower.
that only works with a carb with no filter. and gain more power
Jase Rudolph That’s what I heard but I wanted to test it anyway. I just know someone would get on my case for not testing it.
@@TheMinuteMasters it's all good fam. appreciate the video tho
Jase Rudolph Thanks man! I’m glad you enjoy them!🤙
these numbers are very close to reality, there is no big gain until you change the camshaft, some characters faked the numbers on dodge, they got at least 20whp with the filter......
It screws with your engine without airfilter
That makes sense.
How much more dust the K&n let in???
I read an article a year ago. They tested a K&N filter and a paper filter. By far, the paper filter captures the most particles. K&N filters are known for letting particles through and coating the sensor wire in a MAF and causing issues.
@@TheMinuteMasters I actually looked into K&N filters the other day when i noticed you can actually see holes in them when you put them up to the light. I THEN PURCHASED A NEW ONE THINKING MY FILTER WAS JUST OLD AND THE NEW ONE WAS THE SAME. IT WAS THE SAME. NEVER WOULD I BUY THESE AGAIN
@@timm1807 You are exactly right! The added airflow performance comes at a cost. People never consider that and the manufacturer doesn’t explain it either. Paper is the best filter on the market.
People will always mouthbad things they hate.
3:19 that makes sense
That's why there are "trumpets" mounted od sport carburetors and throttle bodies, when there are no filters or just meshes.
K N lets more dirt in, fine for racecar engines that get rebuilt often
My 350z would go into limp mode if you removed the filter
Tom K That’s probably a fail safe mode.
More air more gas , k&n is for those people like to press Their paddle hard to get performance , if you are a cruise kinda driver go for paper air filter keep your vehicle runs smooth on the highway and good gas mileage
You got it!🤙
Youre wrong about turbulence. When you remove the filter it leans the car out too much and loses power.
Charles Seara That’s true. Either way, it’s not a good strategy to increase horsepower on a stock engine with no tuner.
They think?
Joe Swheat An educated guess from people who know more than me.
removing air filter gives you more power only when your moving on streets creating wind ramming .car sitting in a shop even with fan isnt the same thing.
Alexander M That could be try. I guess we won’t know for sure until they invent a mobile dyno.

Gasoline
But this is only one measure. This doesn't address how much dirt us getting dumped into the engine.
This is true.
Keep intake Always Stock IT already works Like a "cold Air intake"
otoot kol I sure did keep it! 🤙The OE intake is straight, inducts cold air, and big.
removing it dosent give a Power increase!!!!.... Fast and Furious is a LIE hehe
Hemath kumar Yup! Lol I could do a bunch of videos myth busting those movies. Still fun to watch though.🤙
Don't deviate from the manufacturer's specs to try to gain some cheap hp. Remember anytime you do something to gain hp, you impact performance or the life of your vehicle. Filters are supposed to filter air.... and provide clean air to the motor. These aftermarket filters that claim they increase hp don't filter the air as well as the manufacturer's paper type. And many use an oil to attract the dust and dirt because the mesh is not as dense. So you always end up under oiling, over oiling, or not oiling enough. You think you're saving money by buying a washable filter, but the cleaner and oil costs around $50 and you need to do it every 6months or so. Not to mention, the Vehicle's ECU is preset for a certain fuel air ratio, so you're achieving nothing. I'd go oem every day of the week!
I agree 100%! I ran this test just to show what possible gains can be had with these filters. Most agree 5 hp is low enough to be within error territory. Plus these filters cause all kinds of issues on MAF sensors.
@@TheMinuteMasters thanks for your response, and yeah you're right about the sensors. There may be some aftermarket washable filters that filter as well as the oem, but then you're not gaining anything in hp and just paying an exuberant price for a filter. Lol. Everyone thinks it's because the oem is trying to make money, but the ecu settings are designed for that filter, not high flow. Have you thought about a follow up video to test the filtration quality of K&N vs Paper?
@@funcool32 No problem man!🤙 Exactly! Most performance parts don’t work on stock vehicles. Modified and tuned vehicles is a totally different story.
I haven’t. I guess I could put a secondary filter in the intake to measure/show the dirt that gets through the K&N filter.
no easy horse power
Exactly
3:30 NO!
Air filter can't modify the air flow as modifying it to pass the rest of the induction ducts... I am sorry but you need a crash course of fluid mechanics and physics to understand how wrong was what you said.
It's a restriction, a known restriction (ecu) which adds to how the fuel mix is controlled later on the injection.
An old carb round filter could, maybe, but no it's just a restriction... And with out it the low and high mix adjustments would require change, to later adjust when putting back the filter.
Good experiment on the dyno, but it is one of thousands already done since the 1800's... Well minus a modern dyno of course
I don’t pretend to be a scientist. I just regurgitate what K&N advertises and what floats around the internet.
The ECU definitely is a restriction that is not correctable without modifying it. My video is to show case this product in plug and play manner as advertised.
You did not need to go at him like that.
With out tuning the system of the car to actually require more air volume... Any intake mods, including a better filter, ARE USELESS OR EVEN COUNTERPRODUCTIVE
No better fuel economy, and no more power... Perhaps even less
Same for the exhaust
If turbo a better inter cooler (thicker) could actually improve low end power... But then again the system is programmed for that TMIC resistance to flow, so no not even that
I agree 100%! However, OBDI vehicles need to have the ECU removed and modified in order to tune them. That procedure is hardly plug and play which is how K&N advertises their CAI.
He just showed in the video the K&N increased power without doing anything else. Was it much power? No it wasn’t but it still increased.
