Eventuri Carbon Intake System – Audi B9 S4 / S5 Eventuri

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.

The Eventuri B9 S4/S5 intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. Here are the details for each component and the design ethos behind them: 

Each intake system consists of: 

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