K&N Air Filters Reviews


160K mile BMW 323is

Reviewed By K. David H (Alamo, CA) Reviewed for a 1999 BMW 3-Series —4/17/2009 10:33 AM

I received a marked improvement in the responsiveness of my BMW immediately after installing the K&N. Leaving stop lights the car's rear wheels broke loose several times. It was necessary to adjust the way I accelerated the car to avoid this from happening. The car had never done that before. Highway 0-60 has improved also. It has given new life to an old car. Wish I'd put the K&N filter in years ago.

K&N 57 Series FIPK Air Intake (50-State Legal) Reviews


I love it!!

Reviewed By Andrew G (Saint Louis Park, MN) Reviewed for a 2001 BMW 3-Series —11/18/2014 5:55 PM

I added it to my shopping cart three times before I actually bought it. $270 for some sheet metal, filter and some tubing, seemed like to much. Finally I decided to buy it and really excited that I did. Easy to install, looks clean in the engine bay, and makes the sounds I was looking for. Still don't have exhaust on my 330CI so all I hear is the sound of the engine, which it not that pleasing to listen too. With the intake installed I don't mind driving with the music off. Worth the money.
