C from Hoboken, GA said, "I first purchased a K&N filter in 2002 for my Ford F-150 pickup. I then installed one in my 2005 Nissan Maxima, In 2006 I installed one in my Toyota Tacoma pickup. I just purchased a 2008 Toyoat Avalon and have onstalled one in it. I noticed an immediate increase in acceleration and my mileage has improved nominally. They are easy to service and well worth the investment. I have installed the one I had in my Ford Pickup in my father-in-law's 2003 Ford F-150 pickup and he has noticed the difference also. Keep up the good work.Dave Hoboken, Georgia"
