"I've used K&N filters for 11 years starting with a Ford Explorer thru a Powerstroke F350. When my wife purchased a new Frontier 4x4 it was a no brainer: get a K&N. On over 6 vehicles I've owned and equipped with K&N, I always see a modest increase in midrange performance as well as bettter gas milage. Very easy to clean and reoil. I've probably saved a fortune over the years with K&N. Highly recommended!" —Franklin H from Coldwater, MS bought a K&N Air Filters for a 2004 Jeep Wrangler.
"I'vr been using K&N air filters for a long time, along with several other K&N products. In my opinion they are of the highest quality and relatively easy to clean, once dirty. On the average, I do mine every 35,000 - 40,000 miles. Besides, using the best doesn't cost that much more -- on my four cars." —Doug M from The Woodlands, TX bought a K&N Air Filters for a 2004 Jeep Wrangler.
