I've always used K&N filters on my motorcycles, So why not my truck. Washable and good for life. It's a win/win.

Fit perfectly in my F150, 5.4l. It seems to be getting better mileage, by 2mp over the last 2 tanks full. Thanks for the great service, product arrived 1 day early.

Everytime I buy a new vehicle, I install a new K&N air filter. I've put them in my GT40 replica, '90 T-Bird, '95-T Bird, '97 Explorer, 2000 Navigator, 2008 Mariner, 2004 Aviator, and I just ordered one for my '06 Expedition. I haven't used a K&N oil filter yet but I'll give it a try on my next oil change.
