Typical K&N built very well. Fits perfect.

I'm not sure about the horsepower gain, but performance does seem more to have improved. I also added Bilstein shocks from Auto Anything and a Magnaflow muffler I bought locally. So the engine is breathing better, sounds better and the truck rides better. I've used the K&N air filter replacements for years and been very happy, but this time I wanted to go for the added performance the FIPK offers.

I replaced my old Injen nano fiber filter for the K&N. The K&N was about 2" taller than my old filter which made a huge difference with sound and performance. I highly recommend this product
