"The first time I encountered the superior flow of a K&N filter was via an in-store display that showed the air flow through a regular OE filter and through a K&N filter. I have since installed these filters on two Chrysler minivans, a Pontiac Montana, and a Ford Focus. I also convinced my father to install one in his Cadillac Northstar engine. For the price, the filter pays for itself after about three OE replacement filters, but by then is still ready to work for most of a million miles!" —James H from Grand Rapids, MI bought a K&N Air Filters for a 2002 Ford Focus.
