Enjoy the style and worry-free operation with our seamless one-piece airbox design. Unlike competitor multi-sectioned airboxes, our approach eliminates the risk of air leaks, complicated installation, rubbing noises, and parts loosening over time while maintaining the smoothest internal airflow path.
 
Sound is as integral to your driving journey as power. Immerse yourself in the addicting symphony of turbocharger spool, engine throttle, and diverter valve noises that resonate from your twin-turbo RS engine. Unlike the factory airbox that suppresses all sound, our intake system embraces the excitement with a refined and exhilarating audial experience that perfectly complements the enhanced performance of your build.
 
Our carbon airbox is equipped with multiple air supply avenues to support various power and build levels. The front and expansive air inlet captures outside high-pressure airflow and acts as a ram air design. Additionally, the filter plate louvers draw in extra air as required from the low-pressure zone below the intake. These dual zones provide an unrestricted air supply across the entire filter, eliminating power limitations for even the most extreme builds.
 
Uncommon in consumer-level applications, our integrated velocity stack strategically amplifies and smooths flow dynamics at a vital point as air enters the charge system. This advanced design element provides a gradual reduction from the substantial 5" air filter to the smaller turbo inlet. By precisely controlling this crucial transition, our intake system accommodates increased turbocharger and engine airflow demands with minimized drag and power-robbing turbulence.
