I know some who have had trouble with the K&N, and others who haven't. I have over 120K on mine. I did NOT expect any performance gains, I just wanted a washable, reusable filter. One less trip to the local auto parts store.
If you are capable of following the maintenance/recharge directions exactly, you'll be ok. If you can't , stay with the paper throw away...

K&N air filters have been around forever and ive never heard of them causing problems until i read this stuff. They use a special oil to catch dirt so even thought u can see light through them doesnt mean dirt will go through them like someone previously said. I think most of them are said to be good for 1 million miles if you clean and re oil them on time. They are probably the best air filters ever made so im not sure where some people are getting their information. I could see screwing up the MAF if the user puts way to much oil on them after they are cleaned, but if you have common sense that shouldnt be a problem.

You need to learn about "turbo dusting"!!!
K&N airfilters were developed for off road races like Baja, where the OEM paper filters would plug up with dirt, the K&N's wouldn't.......guess where the dirt goes????

I got an AEM dryflow filter, no oiling, and you clean it with they're solution with water, and let it dry. No oil, no messing up the MAF. I have a K&N Intake, and I replaced the filter alone with an AEM one of comparable size.

This is a truly independent test. Lots of desert dust. This is with a K&N in my truck.

A k&n airfilter does NOT let dirt get sucked into the engine as stated before!

The unique design features multiple layers of oiled cotton fabric which captures the airborne dirt particles. These dirt particles cling to the fibers of the filter and actually become part of the filtering media.

That is straight from K&N website.
Ever look at both sides of a panel filter? The one side will be dirty and the other will look brand new. Also the intake tube will have no dust residue on it therefore it is not letting dirt through.
K&N has thousands of hours of R&D.

If you read my Used Oil Analysis it clearly states that my oil is excellent. Low engine wear and I like the part where they mention about wearing white gloves when they assembled this one. If the K&N was pouring in dirt the results would have been different. I live in a dust bowl.

so all u guys are guna sit there and tell me that by removing ur stock restrictive air box and tubing and replacing it with a piece from K&N that ur not gaining performance or MPG guess what ur full of **** my buddy has on on his ranger with a 4.0 and he went from 17 to 19-20 and there is a huge difference in power u can feel it as ur driving and yes the intakes sound awesome and the sound isnt from more air turbulence it because there is no restriction to slow down the air when ur shop vac is sucking in air it sounds like the same thing because theres no restriction wow what a surprise there is no way u can sit there and tell me its not helping or that the K&N filters suck dirt into ur motor u have never seen the inside of a K&N then the out side is dirty the inside is clean

bobby you remind me of the guy from waco
That's good Einstein, if it isn't clean, it will filter better!!!

Try holding a new K&N POS up to the sunlight!!



No, here is the problem, it was cloudy in Westland, Mi yesterday:

Being Halloween last night the Exorcist was on. I swear there was a K&N filter box on the possessed little girls night stand. Everything Bob says must be true. I was shocked!!

yea same here hahaha...i dont think there is any convincing takeda that a k&n airfilter makes more power, gets better fuel milage, and lasts longer than a stock paper filter, even though they do. lol

We have another sucker here!!!

I've posted this before, a REAL (not BUTT) dyno test (independent) that
proves there is NO performance improvement with a K&N:

I do HVAC work for a school and i change ALOT of filters. There are 2 types of common ac filters fiberglass and pleated. Pleated have hole in them too and clog up quicker than the disposiable fiberglass filters cause they filter better. A K&n filter has the some design as a pleated only it is reuseable. We do have some filter with the exact materials that K&N uses on our new units and they do filter better plus they are last for 5 yrs as long as you wash and oil them. If they did not filter as good as they say i would know cause there would be dirt on the coil.

If the K&N filtered better, and clogged up quicker, they would have never worked in off road races like Baja, which they were intended for!!

And, if the K&N wasn't known for dusting turbos, contaminating MAF sensors, etc. , why would they put this in the fine print of their warranty:

"K&N will not be responsible for any other expenses incurred by the customer under the terms of this warranty, nor shall it be responsible for any damages either consequential, special, contingent, or otherwise; or expenses or injury arising directly or indirectly from the use of the K&N Air Filter"


Just for comparison, here is Purolator's warranty:

"In the event of an engine failure directly caused by a defective Purolator filter, which was properly installed and changed following the engine manufacturer's recommended service intervals and was in accord with current Purolator catalog recommendations, Purolator warrants that it will pay for the repair or, if necessary, replacement of an engine or other parts damaged as a result of any defect in any of our filters"

Big difference, eh?????

And you won't find statements like this on K&N's website:

"Purolator filters meet or exceed OEM (original equipment manufacturers) requirements and are tested in accordance with the Society of Automotive Engineers' test procedures.
New car warranties remain in effect when Purolator filters are used in accordance to the engine manufacturer's change intervals"

I heard my trucks hood latch pop open and I went outside to see what was going on. My God the K&N filter really was trying to kill my engine. I managed to talk Mr. K&N into handing over the Glock before he did something we both would regret. I removed the K&N immediately before it had a chance to rethink what it wanted to do.
DO NOT USE K&N FILTERS if you cherish the life of your engine.




Disclaimer: no 3.0 liter engines were harmed but the Glock was real

They do clog up faster then the pleated..have to wash them 2 times a month vs 1 change out of the pleated.
