K&N Air Filters Reviews

Satisfied K&N user

Reviewed By Willis W (Salem, OR) Reviewed for a 2006 BMW 3-Series —1/19/2014 9:49 AM

I've used K&N air filters in several vehicles in the past, most recently in my BMW. Filter is very nicely made, installation is easy enough, and it fits perfectly (BMW uses included foam gasket for air box cover). Don't expect miraculous increases in power, mileage, etc. The economics do it for me: A K&N pays for itself after it's outlasted 2 or 3 disposable filters, and only seems to need cleaning/re-oiling in our conditions (paved road use) every 50k miles or so.

With the AFE air filter now installed and having driven my BMW 400 miles, my gas avg mi per gal has gone from approx 28 mpg to 30 mpg. not to mention better throttle response.
