I recently purchased a C&L Intake Plenum and the reason I got it was because I have a 75mm TB already on it and I heard that I needed to upgrade the Stock Intake to the New Plenum Intake so it could handle the larger TB. Now my question is how much gain will I get from this swap? Also how much HP do you think my car is pushing now?(look at my mods in my signature) The car runs great and it sounds bad azz with the O/R exaust. Nothing sounds better than the rumble coming from a Stang with no Cats!!!
