CAP 3.0T Post Throttle Valve Charge Pipe Kit | 2017-2025 Audi B9/B9.5 S4, S5, SQ5

Exceptional product quality and engineering. The fitment was flawless, installation was straightforward, and the change in both appearance and performance was immediate. Throttle response is sharper, airflow is clearly improved, and the car finally feels like it can breathe the way it should. This upgrade completely transformed how the car drives. Build quality and finish are top-tier. This is only the beginning of the Nachjäger build—charge pipes are next, with additional CAP components planned as the platform continues to evolve. Very impressed with the product and the direction CAP is going.”
