Product Reviews

  I have been using K&N air filter on My wife's 2010 Subaru Outback. It works great and saves me money At the car Dealer servicing.
Robert Farley Bellmore,NY
  The K&N air filter for my car was easy find on the website, and replaced the old air filter perfectly. The air filter was delivered as promised, the web site was easy to use, a great experience. I use K&N air filters in all my vehicles.
Mick Wagner Colorado Springs
  Great, I love my filter it came fast no premature A+. Would like to have a few more stickers because they don't seem to stick to glass very well.
Dan Arpie New York
  Great air filter. I would only suggest that you add some indicator arrows to the orientation to the inlet or to motor on the base of the filter seal.
