"Received the K&N Air Filter for our 2008 Avalon in just a few days after ordering and put it in the same day I received it. Perfect fit. Haven't driven enough yet to tell if my gas mielage is better, put seems to run with a little more power. Had bought one for my 2009 Frontier V6 a few months ago from AutoAnything and have picked up about 1 mile per gallon more with some increase in power. Very satisfied with everything." —Leroy R from Sweet Home, OR bought a K&N Air Filters for a 2009 Nissan Frontier.
