"Intake it great, installed in an hour and made a world of difference. Throttle response is only slightly touchier as expected, power gains are subtle but noticeable. The sound is the real kicker. Above 4500 rpm the car really growls in a good way. Its quiet at cruising RPMs so the sound isnt obtrusive and only wails in the higher rev range. A great purchase" —Neil P from Bayonne, NJ bought an Injen SP Series Cold Air Intake for a 2009 Acura TSX.
