• Description:

  The Genuine Audi Air Intake Hose 8T0129599 OEM is the factory-engineered left inlet air duct designed specifically for the Audi RS5 8T equipped with the high-revving 4.2L V8 FSI engine. This component forms a critical link between the airbox and throttle inlet, ensuring unrestricted airflow, consistent air pressure, and maximum engine performance under all driving conditions.

  Constructed from heat-resistant reinforced rubber with precise molding, this OEM intake hose prevents air leaks and maintains perfect fitment within the tight RS5 engine bay. It’s built to the same specifications as the original part installed at the factory, guaranteeing reliability and performance for both street and track applications.

  Why Choose Genuine OEM

  Audi’s Genuine Air Intake Hose 8T0129599 is engineered for precision airflow and long-term reliability. Aftermarket hoses often collapse under vacuum or lack proper internal reinforcement, which can cause airflow turbulence or MAF sensor faults. OEM construction ensures perfect internal flow geometry and thermal durability under high-performance engine conditions.
