Filter is a great product. My vehicle runs smoother and has new life to it.
William T Whalen, Madison, Wisconsin
This is my 2nd vehicle now with a K&N air filter. This vehicle has noticeable more power on start from a stop and I have calculated a 3.1 MPG increase with no other maintenance performed on this vehicle. I received a recommendation for a K&N air filter from a friend and have also continued that practice with my friends and family. Great investment for any vehicle of any year.

Finally I had decided to change original filter to K&N. Overall performance of 2.0 liter boxer had truelly increased and fuel consuption became more efficient. Thank you for a great product.

Very quick delivery. Will shop there again.
Chris Refaei, Houston, Texas
Great filter, and ease of installation is as simple as knowing how to install at new air filter. Got this filter for my wife's Altima SL. Changed it out the night before and that following morning my wife knew something was different. Increased throttle response and a little power increase, so at least from that experience of her's, I know the filter does deliver. Will be getting a set of filers for my future Infiniti Q60. Thanks K&N
