K&N Air Filter
By Bruce
I've used K&N filters on my last three vehicles and think they work well. This one is in a diesel F250 and based on tracking the numbers, has given me a little more than an extra half mile a gallon in fuel efficiency, which is a nice bonus. The filter will typically outlast any vehicle it's on with it's million mile warranty. It can by cleaned and brought back to virtually new condition. And with the cost of a stock air filter from Ford running around $50 I'm easily ahead in the long run, never mind the saving on fuel, or better performance.This particular model, which was not just the filter but included a new version of the box the filter sits inside when installed on the vehicle, was a bit difficult to install, seems the box is designed to compress the filter a bit. As a result it seemed at times that the studs that held the top of box to the box itself were too short, making starting the nuts difficult - especially in an already cramped engine compartment.All in all, well worth the time and money, and as a long time K&N user, I will continue to be one.

Increased gas milage.
By Martha J. Jewell
I had this installed in my 2005 Ford 250 turbodeisel without a problem. And I got 3-5 extra miles per gallon on the highway and 1-2 in town.

Fantastic Product!
By John Kessler
My Ford dealer told me Ford would put them on as stock equipment, but the price would be too high. What a shame.I have a diesel so mine cost $195.00. But when you see how big it is and how much they had to replace of the diesel air intake system it's really a bargain. It will pay for itself in 3 oil/filter changes.I had one on my Expedition and my idle RPM went up 150 RPM, my mileage went up 15% too!Good buy!TaosGuy
