Bill's opinion On K&N Air Filters - Tip Of The Week 

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.

Comments from a very wise man with advice.

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.

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 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.

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 RU-vid.

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

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.

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.

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.

If you live in a dusty area and want a full time hobby of cleaning your air filter, get a K&n

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.

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

Are these oiled from the factory ?

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.

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

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!

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

Let's more air and more dirt.

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!

IMO K&N filters are NOT a good product. Many independent testers on RU-vid 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’m a heavy equipment technician and I work on equipment worth millions of dollars and not a single one of them uses some shitty oil type filter. They’re all paper primary’s with a paper or foam type secondary. K&N and similar are garbage. Increase airflow is gained by A: more surface area on the filter or B less filtration.

If their filters so are good, maybe K&N would kind enough to tell us which vehicle manufacturers 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 ?

Scip the oil

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.

Great political reaponse. 👏 😂

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.
