Do you consider a "dusted turbo" a catastrophic failure? The engine will still run, but many owners have had to pay for the turbo replacement due to the warranty being void from using the K&N!!!


Also high Si in UOAs is an indication of dirt being ingested from the K&N will increase engine wear.

Bottom line, there is no performance advantage to the K&N, why would anybody want to risk the damage the K&N can cause (MAF sensors, IAC valves, and throttle bodies gummed up)?

Again, you won't find this statement from ANY manufacturer of OEM paper air filters:

"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."

run a turbod motor through a dusty desert race with a paper filter... when your turbo is ruined will you swear off the paper filters too?

let me re-phrase my question, have YOU ever seen a catastrophic failure first hand on any engine solely from the use of a K&N filter?

WRONG!!! That's how K&N filters came out is for races like Baja! The OEM paper filters would plug up with dust in no time, the K&N's wouldn't. Same amount of dust flowing, guess where it was going?

Nope, and I never will!!! I would never put one of those on any vehicle I own!!!

Hey bob and mike, WHAT IN THE HECK ARE YOU TALKING ABOUT? with regular re-oiling every 5000 or so miles (or every oil change) it does not suck in dust! ive had my k&n for about 4 years now. I had to replace a head gasket and the engine looked beautiful. No grime or anything. I completely agree with sweetwater, k&n's rock. I have actually referred k&n to 6 or so friends and 3 family members, all with great success. No crazy gumming up the MAF or dust getting in my uncles turbo on his diesel.

As much as Bob sounds fanatical about this, he is right. While not everybody seems to experience issues, K&N filters have been tested many times and the quantity of particulates they allow through is significantly greater than traditional paper filters.

hey 97 ranger xlt, I have the same truck 97xlt 5 speed, you think these are dogs they are, but my 2000 sonoma 2.2 auto was worse, THAT was a real dog, and rode like crap to boot.

 

[ILLEGALCONCEPTS]

I've had my K&N on my '96 for YEARS. I've only cleaned and oiled once in that time. I clean my MAF just about every other year. My uncle works with Ford and International dealing with the deisel engines. I've seen many articles from Ford about the down sides of K&N. I've had many discussions over them as well. Am I sorry I bought one, no. Would I but one again, No. Did I put one on my wifes new Subaru, NO! The only reason it is still in my truck is because I am lazy LOL. I will be switching to a dry flow filter before summer. There have been too many discussions about this and I really don't want to but a new MAF before I need to.

i installed a K&N back in 2000 on my 93 ranger and when i sold it last year it still had it on there and i never had a problem with it gumming up anything,i also installed a drop in K&N on my girlfriends 07 mazda3 20,000miles ago and no problems at all,i'm sure some people have had problems with them but i still don't think there any worse then paper filters

WRONG about what? I didn't make a statement i posed a question....
