Owner reviews for air filter

Micron air filter to block pollen and dust. It also has a charcoal filter to stop odors from entering the car

on my turbo it revs a little faster.

I dropped one in and got better gas mileage, noticable power increase (slight), and a badass sound.

I've used it in a few of my cars, and have noticed a very slight (~1-2mpg) increase in mileage. Power, eh, if there's any I can't feel it...

I had installed a K&N air filter and noticed a good increase in power and fuel economy.

K&N's work great, just don't over oil them. I've been running them for years on all my cars. No problem with the Touareg either in 10K miles.

The only thing im using is a KN Drop-In Filter and that's it.

basically the dirtier a paper filter gets the less it flows...not true for K&N

I have had a K&N in my 1999 Passat for over 20,000 miles. No CEL's or any other problems. I didn't notice any siginificant performance gains, possibly a 1 mpg increase in gas mileage. To be safe, I haven't put a K&N in my 2001.

I had a K & N put in my 2000 Passat and same thing happened to me. Turned off car and next time I started it, I got the check engine light.
