Eventuri carbon intake system for Audi S4 /S5 B9

Tailor-made carbon intake system / intake solution, for real power and torque increase for Audi B9 S4 / S5 from Eventuri

• Performance increase: 13-17hp, 15-20ft-lbV-Box
• Acceleration: 100-200 km/h reduced by 0.5 seconds

Eventuri's Audi B9 S4/S5 intake has been designed to give the turbo a less restrictive airflow whilst maintaining low inlet temperatures. The S5/S4 engine bay heats up very quickly, so an open system would result in better airflow but at higher inlet temperatures. Therefore, the airflow path from the front grille to the turbo inlet has been completely redesigned with a highly efficient sealed system. The restrictive OEM airbox and flexible plastic pipe have been replaced with a venturi filter housing and duct system with smooth transitions. In addition, by removing the folded OEM pipe and replacing the filter with our patented and one-piece venturi housing and rigid pipe, the airflow is much smoother as it enters the turbo inlet. The resulting performance increase and aesthetics are groundbreakingly innovative for this platform.

The Eventuri DifferenceThe B9 S4/S5 Eventuri system uses our patent pending carbon fibre housings with our bespoke Gen 2 filter providing an aerodynamically efficient airflow path from the filter to the inlets. Not just another filter with a heat shield, but a unique design that induces the Venturi effect.The intake was VBOX tested on the road to record acceleration from 100-200Km/h. The tests were carried out on the same track - and on the same day to keep variables to a minimum. The results show that acceleration times from 100-200km/h have reduced by almost 0.5 seconds, which is a significant improvement at such speeds. This shows that the gains measured on the dyno are not representative of how the intake will perform on the road when it has the right flow conditions - on the road the intake shows a greater gain by reducing acceleration times compared to the dyno.

Summary of acceleration results:

• 60-130mph with original airbox = 14.72 seconds
• 60-130mph with Eventuri intake = 14.24 seconds
• 100-200Km/h with original airbox = 12.45 seconds
• 100-200Km/h with Eventuri intake = 12.12 seconds

The improvements arise from a combination of reasons:
