Ever since I put the new K & N Air Filter in my 2007 Ford F-150, 5.4 L, My MPGS' have gone from 13 mpgs' to 16 mpgs'. Haven't changed a thing. Still the same gas 89 octane, same driving habits, same everything. Man you guys have the BEST. Yes I have tried other look a like filters, but nowhere near the same as the REAL DEAL. K&N is with out a shadow of a doubt the BEST BY FAR. Won't ever see me in the [brand] auto parts store ever again for air filters, EVER. You certainly have my written permission to use my feedback anwhere anytime.

Great product, fast shipping. Truck definitely drives nicer. Easy install, about 1/4 beers time.

Once I replaced the filter (stock) with K&N, my truck seemed to run better. Also the pick up was better. I have used K&N filters on my motorcycles and was very happy with them. Good quality and better performance. Will use on all of my cars, trucks, and motorcycles.

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.

Good fit. I anticipate no problems removing the filter for cleaning, so all in all, it's been a good experience and a good buy for me. I'd indicate how this filter affects my performance, but such things don't matter to me - I don't care.
