Easy installation and adds a little bit of sound when getting on the gas. Only problem, had to trim the heat shield to fit in my 04 f150.

I bought this for my truck, and noticed a immediate increase in horsepower, as well as noise. I have also noticed about 1 MPG gas mileage difference. How ever, this was very very hard to install, and I was not able to get the optional air scoop installed, because of the lack of directions, so that was a waste of money. I would recommend this, but expect to spend some time installing it, and don't even worry about the air scoop, you won't be able to install it.

The Airaid/Roush Air Intake Kit for my '04 F150 FX4 is great. The installation was no problem with the right tools. I like the sound of the engine at higher RPM sounds like it breathes much better. Not much sound difference at low RPMs. MPG for the last two tank fills has been just under 20MPG; I was getting 16-17mpg before. I Highly recommend this kit.
