Looks good! Havent noticed any power/mpg gains yet. It didnt install very easy. Only 2 of the holes for the box lined up with the trucks chassis. I had to drill the 3rd out to install and the 4th bolt wasn't possible. The plastic tube and rubber couplers all seemed too short. Which made it hard to install. The opening in the side of the box near the fender doesn't line up with the fender openings for the truck. Not a bad product just needs some updates from aFe to fit better.
