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

Wow I can't believe how good this air filter is. I drive a 2014 Ford Focus Hatch automatic with dual clutch transmission. I bought this air filter based on the recommendation of a friend. I really can't believe what a difference this air filter has made in my vehicle. This air filter has great improved my low end torque and acceleration. It has not made into a sports car but there definitely is a noticeable improvement. Periodically I would get that transmission stutter from the dual clutch transmission, not often but once in a while. With this new air filter I have not experienced that once. This air filter has worked so well I am thinking of investing in the air intake system for $299. There is no reason you shouldn't have on of these filters in your car. A life time part for $60. Instead of paying $20 every 10,000 miles. This really is a no brainer.
