K&N Air Filters Reviews


K&N Filter replacement

Reviewed By dennis t (DALLAS, TX) Reviewed for a 2011 BMW 5-Series —3/28/2014 8:53 AM

After getting on for a 3 series I also own I was surprised by just how easy the one for my 5 was to install. I wasn't under the hood 5 minutes to complete the job. While I haven't had this filter in but for a few days, I'm expecting similar results to all of the others I've installed in my cars. Typically 5-10% better fuel economy so it doesn't take all that long to recover the initial cost.

Volant HV Cold Air Intake Replacement Filters with Donaldson PowerCore® Filtration Technology Reviews


Volant Air Filter with PowerCore Filtration

Reviewed By Charles L (Weehawken, NJ) Reviewed for a 1999 BMW 5-Series —7/10/2012 11:56 PM

The first one I used only lasted 30,000 miles before it was noticeably dirty throughout the inside of the flutes, but that's probably because of the polluted city environment my car was driven in. The Volant air filter did a great job in keeping the throttle body clean, better than the K&N reusable filter it replaced in the cold air intake system. When the Volant is new, it may provide a slight throttle-response and gas mileage advantage over other types of filters common to cold air intake systems, but when it starts to clog there'll be a noticeable drop in gas mileage and throttle response. When I replaced my dirty Volant with a clean one, the improvement in throttle response was instantaneous. This is an excellent air filter to use if you don't mind spending the money to replace it every 30,000 to 40,000 miles.
