The APR PEX Intake System is a complete induction upgrade for the 3.0T EA839 that replaces every component from the inlet scoop to the turbocharger inlet, removing the factory necked down restrictions for the largest inlet the engine bay allows. A 7 by 7 inch washable pleated cotton gauze filter with a 5.5 inch frontal inlet and 4 inch outlet feeds a heat shielded PEX airbox, and a high temperature composite turbo inlet uses thin wall construction to maximize internal diameter. Airflow improves 31% over stock, from 400 CFM to 525 CFM, adding 19 AWHP and 20 AWFT-LBS on an APR Stage 1 93 octane S4. A billet turbo inlet adapter accommodates larger turbochargers, and OEM gaskets, clamps and hardware are included.
