Designed around the Chassis
Boden Autohaus Blow Off Adapter is precision-engineered from 6061 forged aluminum and designed to integrate seamlessly between the OEM diverter valve and intake plenum. This configuration allows the factory recirculating system to vent to atmosphere, helping reduce intake temperatures while delivering the iconic blow-off sound associated with turbocharged engines.
Each adapter is finished in a clear hard-anodized coating to protect against the elements and maintain its appearance over time. The kit includes all necessary components for a straightforward installation, including extended hardware for a secure and proper fit.
