Eventuri Carbon Fibre Intake – Audi S4

AUDI B9 S4 S5
Performance Gain: 13-17hp, 15-20ft-lb
V-Box Acceleration : 60-130mph Reduced By 0.5 Seconds

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. 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. Each intake system consists of:

Carbon Fiber Venturi housing with intergated tube
High Flow Generation 2 Filter
Carbon Fiber Intake Duct
Carbon Fiber Front Scoop
High Quality Silicon Couplers and OEM Spec Hose Clamps
Laser Cut Stainless Steel Bracket Work
CNC Machined Mounting Stubs
