CTS Turbo intake system for Audi A4/A5/S4/S5/RS4/RS5 B9

The CTS Turbo intake system is designed for Audi A4, AllRoad, A5, S4, S5, RS4 and RS5 vehicles from the B9 generation, model years 2017–2021.

The system uses the original air inlet and is designed to direct cold air efficiently into the intake system. The air then passes through a high-flow air filter with a large 6-inch velocity stack-style opening, helping to improve engine performance.

The one-piece, purpose-designed silicone connection components allow the smoothest possible airflow into the engine. On a standard vehicle, quoted gains are in the range of 10–12 hp. The system components work together to provide more power and torque throughout the rev range, along with a more pronounced, race-inspired sound. The sound of the turbocharger spooling and the diverter valve releasing pressure is noticeably louder.
