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.
