Here is a report that backs up what CR said about the K&N filter. And I agree that it is snake oil..after all...I have that snake oil under my hood, and it really was a waste of money.amerijeep said:I don't buy it. I think they are snake oil. Consumer Reports said the same thing. It was on their site at one time. I'll check to see if it is still there later.

you definately do notice the difference in the rev range..
it revs a;lot harder.it also sounds alot more vicious thanks to the sucking sound.
Ive caked it in mud and debris..taken it off to see if anything got through.. not even a slight dust skin lay on the inside of the tube.
Ive read that the K&N filters arent all that flash.. but I havent had any hassles as yet.. and its been in for well over a year now.its a daily driver.. and a weekend warrior.. the filter does get cleaned frequently though.
