Audi B9 S5/S4 Black Carbon intake

The Audi B9 S4/S5 Eventuri intake was developed to give less restrictive airflow to the turbo 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 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.
• 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.
