High-Flow Intake System 6" Air Filter

The CTS Turbo High-Flow Intake is an air intake system designed for B9 Audi A4, Allroad, A5, S4, S5, RS4, and RS5 models from 2017 onwards. It works with the OEM air scoop to direct cold air into the system through a large 6" velocity stack air filter for maximum engine performance. The intake features single-piece molded silicone couplers for smooth airflow into the engine, potentially providing peak power gains of 10-12HP on stock vehicles. It also offers increased horsepower and torque throughout the power band, with a sportier sound and louder turbo spool and diverter valve release.
