APR PEX Intake System - Audi S4/S5/S5 Sportback (B9) - 3.0T
APR has built a reputation for engineering intake and tuning solutions that extract genuine, measurable gains rather than just noise. The APR PEX Intake System is a full replacement solution for the Audi S4 and S5, built to remove every restriction between the inlet scoop and the turbocharger inlet on the EA839 3.0T platform.
This listing covers the Audi S4 Sedan (B9 8W), Audi S5 Coupe (B9 F5) and Audi S5 Sportback (B9 F5), all fitted with the 3.0T EA839 engine. Unlike partial intake upgrades that neck down to factory diameter to remain compatible, this kit replaces the entire intake path with thin walled, heat resistant composite tubing sized to the largest inlet physically possible in the available space.
Key Features
- Full replacement intake, from inlet scoop to turbocharger inlet
- Up to 31% more airflow than the factory intake system
- Improved turbocharger efficiency and faster spool response
- SKU CI100072
Vehicle compatibility, OEM part numbers, and fitment notes are provided in the tabs above. Please confirm your S4 or S5's exact chassis and engine code before ordering.
