Edward, Goodyear, Arizona
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!

Very satisfied.

K&N filters allow greater air flow. The factory replacement filter is not as efficient as the cold air intake, but not $350 either. Excellent for what it is. No huge leap in performance in my F-250 diesel, maybe a smidgen better mileage. It's better than a paper filter in my view.

John Gates, Shreveport, Louisiana
Product shipped in a timely manner. Was easy to install and fit properly. Don’t know about fuel mileage as I do not drive truck enough to worry about it.
Juan Flores, San Diego, Texas
I run K&N filters in all my vehicles either bought online or in store and as always I’m always satisfied with the performance of your products.
