K&N Air Filters Reviews


Great quality

Reviewed By Garry Y (Tamuning, GU) Reviewed for a 2010 BMW 3-Series —6/29/2016 6:19 AM

The quality of the air filter is top notch compared to other air filters which flimsy. The ability to wash it and reuse it makes it stands out above other air filters. Overall, great quality filter.

K&N DryCharger Air Filter Wrap Reviews


Must have, great product, but a bit pricey!!

Reviewed By Gilbert M (CREEDMOOR, NC) Reviewed for a 2005 BMW 3-Series —3/22/2016 7:47 AM

I recently purchased an FIPK for my 2005 BMW 325i from AutoAnything and I also got one of these filter covers. You can call it a pre-filter for sure because it does add an extra layer of protection. The material is excellent and this is a must have item if you have one of these filters in your car. The only thing is it is a bit pricey at almost $30, now if it was $10-$15 I think it would be a lot more reasonable. Personally I wouldn't think about having a cold air exhaust without one of these!!

Great replacement for the K&N that came with my CAI

Reviewed By Winston Y (FERNDALE, WA) Reviewed for a 1999 BMW 3-Series —3/10/2016 10:55 AM

I didn't want to bother with the cleaning and oiling of the K&N filter that was installed in my car. AFE had the perfect replacement and installation was easy. I cleaned my MAF at the time of installation and and got a better idle as well, and I believe this was due to the oil from the K&N filter contaminating the wires.
