This was the first upgrade I did on my 02 f350. The install had some issues like the main housing seemed outa shape all the holes didn't line up all that great but made it work. The other thing is the ghetto battery hold down for the price it could be better. The the intake tube 2 outa the 4 hole weren't even close to lining up. Other then those issue for me you can defently fell the little extra power. Be aware of the extra noise
