Customer Feedback

I have a 1999 F-150 4X4, I purchased one of your filters for it at the local Auto Store. I can't believe the power it's giving the 5.4L Triton. Throttle response is there, the truck was by no means powerless before this, but now its very quick! I love your products, and soon hope to purchase the FIPK's! Thank You K&N for being a unique resource for my vehicles needs!

Thank You

Great product! Fit perfect and works better than the stock air cleaner. I have a K&N air cleaner in my Ford diesel pick up and it works great.

Installed the cold air intake in my 2014 Ford Explorer Sport. Even with the turbo, the response is improved and the sound is awesome!
