APR PEX Intake System - Audi RS5 / RS5 Sportback (B9) 2.9T 2018-2025

The APR PEX Intake System is a complete induction upgrade for the 2.9T EA839 that replaces every component from the inlet scoop to the turbocharger inlet, eliminating 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, while a high temperature composite turbo inlet uses thin wall construction for maximum internal diameter. Airflow improves 36% over stock, from 484 CFM to 658 CFM, adding 19 AWHP and 17 AWFT-LBS on an APR Stage 1 93 octane RS5. A billet turbo inlet adapter swaps in to support larger turbochargers, and the kit includes OEM gaskets, clamps and hardware.
