Audi S4 Performance Air Intake - APR - PEX - `18-`25. This full intake replaces the factory tract end-to-end to deliver higher airflow for the B9 S4 3.0T.
Built around a PEX heat-shield airbox and a thin-wall, heat-resistant composite turbo inlet, this system maximizes internal diameter where space is tight. Flow increases by 31% versus stock (525 CFM vs 400 CFM at 28" H2O), improving turbo efficiency, response, and sound. A 7" x 7" washable cotton gauze filter provides broad surface area, and the kit includes OEM gaskets, clamps, and hardware for a straightforward bolt-on install. On an APR Stage 1 (93) S4, testing showed gains of +19 AWHP and +20 AWFT-LBS.
