BMC 97-02 Audi S4 I Series 2.7L Biturbo Carbon Dynamic Airbox Kit

The carbon fiber construction of this BMC airbox kit is a notable detail, offering a strong yet lightweight housing for your Audi S4's intake system. This kit is specifically made for the 1997-2002 Audi S4 models equipped with the 2.7L Biturbo engine, aiming to improve airflow to the engine.

BMC's Carbon Dynamic Airbox (CDA) design is intended to channel cooler, denser air directly into the engine. The carbon fiber material not only contributes to a lighter overall weight but also helps to insulate the intake charge from engine bay heat. This can lead to a more responsive throttle and potentially improved engine performance, especially when the engine is under load. The kit is designed as a direct replacement for the factory airbox, simplifying the installation process.

Keep in mind that this airbox kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for specific details regarding mounting and connection to your vehicle's intake plumbing.
