K&N

Reviewed By William R (Madison, WI) Reviewed for a 2004 BMW 3-Series —7/10/2012 5:07 AM

Very easy for a novice (me) to install. Slight improvement in performance and gas mileage. Got an upgraded part for 1/3 of the price of a dealer installed 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!!
