i think doing anything to the intake short of a CAI system isnt worth the time, effort or money. i took my resonator off and all i got was a little more noise. i never noticed the 1 or 2 hp. at that point i put it back on. i really dont believe in short ram intakes because all they do is suck in hot air from the engine bay. so unless you got a cold air system, anything else is a waste.
