Performance Gain: 17-22hp, 30-34ft-lb
The Audi S4/S5 3.0T Eventuri intake was developed to give less restrictive airflow to the supercharger whilst maintaining low inlet temperatures. The S5/S4 engine bay becomes heat soaked very quickly so simply having an open cone system would result in better airflow but higher inlet temperatures. We therefore completely re-engineered the inlet track from the throttle body to the front grill with a highly efficient sealed system. The restrictive stock airboxes and duct feeds have been replaced with a Venturi filter housing and a duct system with smooth transitions to allow the airflow to remain full and laminar. The resulting performance gains and aesthetics are industry leading for this platform.
The Eventuri Difference
The B8 S4/S5 Eventuri system uses our Patent Pending Carbon fibre Housings which provide an aerodynamically efficient airflow path from the filters to the throttle bodies. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect. You can read more about the housing design and how it works HERE
The Eventuri B8, B8.5 S4/S5 intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. Here are the details for each component and the design ethos behind them:
Each intake system consists of:
