HP and Gas mileage both increased

I installed this on a F-150 with the 5.0 and it did make a little difference on the low end. Gas mileage increased slightly maybe. The real big difference is the sound this motor made before when you stepped on the gas, you could really hear the air sucking in the intake. This little device made it quieter. Really easy to install. I had to do some clean up of plastic fibers that was hanging on the back side because it looked like they would drag air.
