Toyota has a similar product. It’s a TRD cold air intake. Uses the same type of filter. You must clean and oil it just like the K&N. If Toyota sells such a product, then I’m good with it.
Just literally replaced my my wife's accord and my pops ranger with k&n. Been using em in both of my civics for 20 years, never had a problem-proper cleaning is key.
I heard Scotty kilmers opinion on these filters but I have used them for 40 years and I have never had a problem. I always got 1 to 2 miles more per gallon each time I used one.
Proper cleaning, totally drying before re-oiling, and proper re-oiling without over-oiling are critical, and will give excellent service and clean air to your engine.
Watch project farms video test. I used to believe they were good too. They are horrible at filtering. Not worth the unnoticable performance gain. I switched next day. Need my engine to last not get a couple extra horses I won't even notice
Did anyone notice he never demonstrated anything using the K&N contraption generosly donated by APC in Mississauga? 😂😂😂. And yes, if you have a Vanagon, the K&N definitely works. For all my other cars, no noticeable difference.
Well I have kn&n filters in all 7 of our cars since 2004. I like kn&n filters cause there reuseable and i can hear my intake/turbo sounds. Compared to cheap paper filter, this reusable payed for it self within 6months. Never had those made up maf/map issues cause i know how to read & follow directions.
It all depends on how close your sensor sits to the filter. I see nissans come in constantly with maf sensors coated in oil that came off of the filter. It happened to my subaru after 3 months of having a K&N filter in the car.
Reusable but you have to pay for the oil. Still cost less than paper for the long run.

Trying it out out of curiosity!
Payed for itself in 6 months? Are you driving 90k miles in 6 months, or 500 miles a day? One air filter lasts 30k miles and costs 1/3rd of k&n....
@@webguy943 Plus the fact that K&N filters cost several times as much as OEM filters to start with
Comments from a very wise man with advice.
After seeing the Project Farm video on this filter which actually tests filtering efficiency instead of air flow I'll never use K&N air filters again.
I bought a used truck a few years back that had one. I kept it clean and oiled properly. The inside of my intake was always coated with dirt and dust. No k and n for me.
My 93 chevy conversion van has seemingly outlived most cars on the road with a k&n filter I put on it for the past 100,000 miles, it has about 350,000 miles on it.
A K and N filter will stop the big shit that matters, gravel, rocks, sticks, leaves.
Project farm test is basically the equivalent of driving through the dessert during a sand storm
I have a K&N air filter housing and filter. I'll be honest it's a pain in cleaning and adding a really thin layer of K&N oil. I usually park my truck for the day and put it in the next day just so the really thin oiling has absorbed/semi dried so the wet oil on the filter doesn't screw with my sensor and bugger it up.
Horse power gain hardly noticeable.
Too much work involved with a K&N air filter in my opinion, considering when buying a disposable you quickly put it in and eventually toss it and buy another, it's time saving.
I do recommend if you do go with K&N kits buy another filter to have previously oiled and ready so you can just toss it in without the wait. I also noticed too that the filter get's dirtier faster which is contributed by thin layer of oil in my opinion which requires more frequently cleaning and going through the process again.
K&N filter does improve my throttle response which is why I'm still running it. Honestly I'll just replace mine when it gets dirty less risk
That’s what I do. I also change my “lifetime” transmission fluid every 30,000 and my 10,000 motor oil every 4000.
The people complaining about K&N filters have trashy cars. No matter if they have Porsche or Chevy the interior is always nasty, and they don't maintain their cars. When something goes wrong they blame the car or the part they added that they installed wrong or didn't maintain properly. Just a fact I've seen dozens of times.
U are a silly man.
@@michaelwolflake4918 Yes, he has well and truly fallen for K&N's marketing spiel🤣
Kendra and Natalie filters.....Nope. I had a Cummins diesel powered truck and found fine dust inside the intake tube after the filter. Cleaned the tube and re-installed everything. Next oil change, found more very fine dust. Ditched the K&N. Every test I've ever seen has had the K&N make the same power as stock, or 1-2 hp more. 1-2 hp isn't worth the added dust that will eventually lead to premature engine wear. If you have a dragster and every hp counts and it's not a daily driver, sure. For the average daily driver car K&N is a waste of money. Watch the project Farm video on TH-cam.
More HP gains than that.

Ive serviced many with KN filters. The mass air and intake tube are always coated with dust stuck in oil.
Inside of intake manifolds also have a grit coating stuck in that crankcase blow by fume oil coating.
OH, THAT is what that pcv is for.
Not a big issue on a turbo car though.
That is more of an issue if you over oil. Out of the box, or properly oiled, oil doesn't escape the filter, they just don't filter as good.
IMO K&N filters are NOT a good product. Many independent testers on TH-cam have shown that, while they MAY marginally, improve the performance of SOME vehicles, they are also quite poor at actually filtering the air. One test I watched showed that using a K&N filter was almost as bad as not using any filter at all. So while your performance MIGHT improve a tiny amount, your engine will not be as protected as it should be.
I saw some of these TH-cam scientists and their methods are questionable... So ANY results they get are null...
I just cleaned my k&n, got rid of those bees, lady bugs and usual trash... and been doing it for 100,000 miles so far is my 93 g20 5.7l conversion van.
i have a k&n on my motorcycle, after its first service "cleaning" i was shocked to see how much dirt was on the butterflies of my intake... it really freaked me out .... this was a replacement air filter not a high performance Exposed air filter.. the air filter was in its air box.
I have been using K&N Filters for nearly 20 years, but, I also use the Pre Filter for peace of mind, all my cars were running on LPG which needs a cleaner burn, and all my cars, Subaru 4X4, Mercedes S-Class and now Mercedes Viano were and are used as Taxis!
Need cleaning every 60,000 miles, but who cares, I would use nothing else but K&N!
Well worth the extra money and great on LPG cars.
I'm dealing with some issues with the 2022 mitsubishi Outlander SE. I actually love this vehicle but I was trying to get the To the fuse Box on the passenger side. Anyway I decided to also do my cabin filter on my 2014 Honda elantra GT and damn I noticed a difference it was even colder in any way.
I'll upload the video I just took in the 2022 mitsubishi and I'm in Las Vegas so it's very hot.The car almost shuts off with the OM and I'm going into autozone right now to get another kn.
Sorry about this damn auto correct text shit
Are these oiled from the factory ?
If you live in a dusty area and want a full time hobby of cleaning your air filter, get a K&n
Scamming people for fifty years more like it. Can't believe they are allowed to lie to people about hp gains. And not have to disclose about the massive amount dirt allowed through all their filters! This is a known thing!
While the K&N filters less than a paper filter, we are talking the difference of like 99.7% filtration and 99.5% filtration.
The K&N doesn’t quite filter as much as a paper filter but if you’re not driving in dusty conditions you’re fine
That’s why you oil them. The oil traps the dust and the filter traps the bigger particles.
why run any filter ?
stick a screen there to stop bugs
do you think its fine if you ocassionally drive through some dustry gravelly areas?
@@Tantium just clean them a little more often
They; not only increase the flow of air into the engine, but they also allow a ton of $&#&# to pass through. Use your brain and stick with OEM
Drop some flour kn it when you put it in the test rig. Watch the paper filter stop the flour and a bunch go through the K&N. You can't even get K&N filters with filtration standard ratings. Its halfway to running with no filter. Why no just drill a 2" hole in the side of the airbox on the clean side, free horsepower!
"Dropping some flour on it" equals to operating your vehicle in the MOST EXTREME dusty condition possible, in reality, driving around the city and light off-roading for 10,000 miles does not even come close to that amount of fine dust.
The reoiling is frustrating and is never perfect and the first cleaning. Switched to AFE’s dry flow filters. Clean it, dry it and done.
How are you liking AFE dry filter and does it make your engine sound better like the K&N
@@a1phamalestudAFE filters are made by K&N
Just put one on my 20 f150 5.0 .ialready smoke any truck i race now its noticeable faster. I never felt a difference on ither cars but that 5.0 is an animal
Let's more air and more dirt.
If their filters so are good, maybe K&N would kind enough to tell us which vehicle manufacturers recommend their use 😆
Toyota sells them on their higher tier vehicles, it's an option on the premium package tacoma's, for example.
@@joemamr710 Fair enough, I didn't know about that
@@paulph12002 Yeah, I found it interesting when I first learned it too. While it is interesting that Toyota sells literal rebranded K&N filters on their "racing" and "extreme off road" type packages, the truths still hold true though. It allows more air in while also allowing in more dirt/contaminants.
While it does allow more airflow, most cars will auto adjust based on the readings of the mass airflow sensor and it will have little to no effect except at the highest RPMs.
And of course you are pulling in more dirt.
In reality it doesn't matter much, though I will say that K&N filters do hold up better in intense conditions like floods or sandstorms, as they will continue to allow air to flow even when wet/saturated with sand.
Many vehicles outside the USA are getting almost 100MPG, So why don't car manufacturers in the USA recommend selling them?
If they really are bad and allow in more dirt/contaminants then Why would Toyota recommend their use?
Why do I get the feeling this lady is actually asking about the external cone type k and n filter not the standard aftermarket type this guy is talking about ?
Individuals who don't do their own oil changes or maintenance should NOT use the K&N (clean & oil) air filters..
Nothing but paper filters everything else is marketing.
KnN filters will not give you any performance gains and let's small particulates through. Stick with stock, The people that engineered the engine know best.
I agree. If the K&N provided a measurable improvement in fuel economy or performance, I think the car manufacturers would install them from the factory. Not sure whether they provide less engine protection however. Have you had first hand experience that they don’t protect as well as paper?
@@donr.ontario Some manufacturers install similar filters, but not K&N...
BUT I DO NOT CARE. I WILL BUY A KNN FILTER FOR MY CAR ANYWAY.
K&n filters have light oil on them that catches small particles and dust . I have this in my ranger for 5 years now and never had a problem with it . My truck did gain hp and better gas mileage
Grrrr i just brought it, will Autozone accept an air filter return?
Great political reaponse. 👏 😂
