Eventuri Carbon Intake | Audi S4 S5 B9

The AUDI S4 S5 B9 carbon intake system from Eventuri was developed to give less restrictive airflow to the turbo whilst maintaining low inlet temperatures. The S5/S4 B9 engine bay becomes heat soaked very quickly so simply having an open cone system would result in better airflow but with higher inlet temperatures. Eventuri 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 the 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.

This intake system is available in black carbon fibre, Performance Gain: 13-17hp, 15-20ft-lb and V-Box Acceleration : 60-130mph Reduced By 0.5 Seconds.
