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 Difference

The B9 S4/S5 Eventuri system uses our Patent Pending Carbon fibre 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 affect. You can read more about the housing design and how it works

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 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

The filter housing comprises of our bespoke generation 2 filter, the carbon pod and integrated tube. The carbon pod shrouds the reverse mounted filter and smoothly shapes the airflow down to the turbo tube which it matches in diameter to the turbo tube. This is a key feature of the intake design where we have removed the requirement for a convoluted rubber hose between the intake and the engine. The filter housing and integrated tube extends all the way to the stock turbo tube and by mounting this to the engine, the entire filter housing moves with the engine. As the engine and filter housing moves under acceleration, it is able to maintain a seal to the duct through the use of an expanding rubber extrusion which is mounted to the face of the duct
