Anthony S., Alliance, Ohio
What can I say but probably the best air filters on the market. I have used K&N Filters since I was in high school (many years ago) on motorcycles, cars and trucks and they have never disappointed me. This one is no different. It really lets this 6.7L Powerstroke breath and you can definitely tell the difference. Haven't had a chance to take it out on the open road and check fuel mileage but that is coming soon. I am sure I won't be disappointed as I have noticed a difference in all of my other vehicles.

Just as other K&N products used over many, I am pleased with this addition to my 2012 F-250. Although early, it appears response and fuel mileage are better than with the OEM filter.

I have installed K&N air filters in all of my vehicles (cars, trucks, quads, motorcycles) for the past 20 years. This one installed in my 2014 F350 turbo diesel truck, like all of the previous K&N filters, is a perfect fit and provides a very noticeable improvement in performance. Thanks K&N!

I have only had the filter in the truck for about a month but so far so good. During this time, I have not towed our travel trailer with it in so I can't comment on the upper rpm level performance of it as yet but it will be put to the test in late Feb. early March when we make a trip to Arizona from California. Overall, it went in very easily and it looks very similar to the Motorcraft OEM air filter. Only time will tell how well it performs but I have had K&N filters in all my other trucks before and they performed flawlessly. I have seen a miniscule increase in fuel economy over the past 3 or 4 tanks of fuel that I have gone through since installing it. Hopefully, it will increase a bit more.
