Out of curiosity - Why do you recommend not using a K and N air filter? I am not a big "gear head engine guy" so I am very much a novice on a lot of that stuff, however I ran a K and N on my 96 Tacoma in highschool and college and never had any issues in the 90k miles I put on it during that time.
The only thing I have every heard was if you over oil them, it can set off your mass air flow sensor?
We are running an AFE dry filter on my wives 4runner.
