Performance Gain: 11-16hp, 12-17ft-lb At The Wheels

The Audi B9 RS4/RS5 Eventuri intake was developed to give less restrictive airflow to the turbo while maintaining low inlet temperatures. The RS5/RS4 engine bay becomes heat soaked very quickly so simply having an open cone system would result in better airflow but with higher Inlet temperatures. We therefore completely re-engineered the Inlet track from the turbo Inlet pipe to the front Grill with a highly efficient sealed system. The restrictive stock airbox and flexible plastic Inlet pipe have been replaced with a Venturi filter housing and a duct system with smooth transitions. Furthermore, by removing the convoluted stock Inlet pipe and replacing it with our one-piece Venturi housing and solid tube, the airflow is much Smoother as it enters the turbo Inlet tube. The resulting performance gains and aesthetics are industry leading for this platform.

The Eventuri Difference

The B9 RS4/RS5 Eventuri system uses our Patent Pending Carbon fiber Housings with our Bespoke Gen-2 filter which provide an aerodynamically efficient airflow path from the filter to the Inlet tubes. Not just another cone filter with a heat shield but a unique design which invokes the Venturi effect.
