K&N Air Filters Reviews


Excellent value

Reviewed By Gerald V (Farmington Hills, MI) Reviewed for a 1998 BMW 7-Series —7/22/2008 10:35 PM

This is the third car that I have installed one of these in. I don't have anything to complain about. The plus is getting a bit better gas milage, more performance, and durability. The last one I had lasted well over 200,000 miles and it was still working well when I sold the truck.

K&N Air Filter Wrap

Reviewed By Matthew B (WARNER ROBINS, GA) Reviewed for a 2016 Ford F-150 —6/28/2016 4:10 AM

I first purchased the K&N Air Filter System. I noticed no difference in power and gas mileage. My vehicle sounded worse than before. Then I purchased the Air Filter Wrap. Noticed that my vehicle was running a little bit better. They should highly recommend the Wrap when purchasing the Air Filter System.

aFe Pro-Dry S Air Filters Reviews


Better then stock

Reviewed By Jose V (Pasadena, TX) Reviewed for a 2011 Nissan 370Z —6/28/2016 12:40 AM

Switch out stock filter for the aFe pro-dry S air filters in my 370z. After two months of use I have notices a 1.1 more MPG so I am very happy with that. I also feel like the car shifts smoother through the gears.
