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

After reading other reviews I decided this was the intake for my 2013 Ford Focus with the 2.0L Duratec engine. Great sound and noticable performance, plus better fuel economy. The numbers don't lie. The provided dyno info was almost exact when I had put mine on the dyno. Nearly 10hp gain through the meat of the power curve.

Installed this product on my 1991 Ford F-150 and what a difference it has made. Definitely gave it more power and about 3-5 mpg better. This was a want for this truck, now a NEED for my other vehicles.
