What does that do? I have seen a few on car but I havent ever read any reasoning behind it. Does it just make the plentum bigger and allow more air? Anyone got any true HP gains with it? Would it be worth having with just I/H/E? Its only $125 so it couldnt be that much of a loss if I didnt like it, it looks cool on the motor. I was thinking of eventualy getting cams and doing mods to the intake of the car, like throttle body and the P.I.M.P. and maybe finding te best place to run a cold air intake.
