ok i put this M1 intake on my 5.9 with the kenne bell 2.2l supercharger. I have had it for about a 2 months now and it feel like i lost power of the line, and in general. Today my buddy that has a 03 r/t durango pull me hard through all gears that i had and ,all he has done to his is a k&n cold air intake. I my mind it should very well be the other way around. SO if you have any suggestions please let me know im pretty pissed off at this P.O.S!!!!!!
