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 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
