The APR Carbon Fiber Intake System replaces the entire Audi S4 and S5 3.0T intake tract, from the inlet scoop through one continuous pipe to the turbocharger inlet. Carbon fiber construction allows thin tube walls that maximize internal diameter, and the system flows 31% more than stock while lowering pressure drop and improving turbocharger efficiency. A washable 7" x 7" pleated cotton gauze filter with a 4" outlet and 5.5" frontal inlet feeds the airbox, and a billet turbo adapter ring allows fitment to a larger turbocharger. On an APR Stage 1 (93) tune it adds 19 AWHP and 20 AWFT-LBS over stock. New OEM gaskets are included.
