K&N Air Filters Reviews


K&N for my 328i

Reviewed By Robert M (Maple Valley, WA) Reviewed for a 2012 BMW 3-Series —2/6/2015 3:29 PM

I have installed K&N Air filters in all of my cars for the past 10 years. They fit perfectly, clean and recharge easily and do slightly improve the fuel economy. Not to mention the low cost over the life of the car. It is a great product and I will continue to use K&N air filters.

I like this filter. It looks good, and I wanted it because it does not require oiling like many cone filters do.

aFe pro-Dry s Air Filter

Reviewed By Mario C (CEDAR RAPIDS, IA) Reviewed for a 2007 BMW 3-Series —11/21/2013 8:53 PM

The quality of this product is without question.I did have a bit trouble to put it in my stock air box. It was as if the size oaf the filter was not right. I put it against to OEM filter and it looked like it was a bit bigger. However this just made the filter to fit snug in the box sealing well on all corners. I have not noticed yet mpg improvement, but it hasn't been that long. I did notice that the engine was holding higher rpms a bit longer making the engine appear more responsive.
