Eventuri carbon intake for Audi S4 / S5 B9 2.9 TFSI

Description

Performance gain: 13-17 hp, 20,3 Nm to 27,10 Nm
V-Box Acceleration: 60-130 mph reduced by 0,5 seconds

The Audi B9 S4/S5 Eventuri intake was developed to provide less restrictive airflow to the turbo while maintaining low intake temperatures. The S5/S4 engine bay soaks up heat very quickly, so simply having an open cone system would result in better airflow but with higher intake temperatures. So we completely redesigned the intake path from the turbo intake pipe to the front grille with a highly efficient sealed system. The stock restrictive airbox and flexible plastic intake pipe were replaced with a Venturi filter housing and duct system with smooth transitions. Additionally, by removing the convoluted stock intake pipe and replacing it with our one-piece Venturi housing and solid tube, the airflow is much smoother as it enters the turbo intake pipe. The resulting performance gains and aesthetics are industry leading for this platform.

The Eventuri difference

The Eventuri B9 S4/S5 system utilizes our patent pending carbon fiber housings with our custom Gen-2 filter that provides an aerodynamically efficient airflow path from the filter to the intake tubes. This is not just another cone filter with a heat shield, but a unique design that evokes the Venturi effect.
