EVENTURI FULL BLACK CARBON INTAKE KIT FOR THE AUDI RS3 8V
The Audi 8V RS3 Eventuri intake sets a new benchmark in intake design. It was developed to constrain the turbo’s inlet path and maintain low inlet temperatures. The first objective was achieved by using 88 mm internal diameter pipes up to the turbo and using the unique Venturi housing to maintain laminar flow. The second objective was achieved by designing a sealed system for the stock cold air intake, thus ensuring the turbo does not draw hot air from the engine bay. The intake duct draws air from the stock intake and has been maximized in volume to allow maximum flow through the filter.
Each intake system consists of:
Carbon fiber Venturi filter housing
High-flow urethane cone filters
Carbon fiber inlet duct
Carbon fiber
Carbon fiber connecting pipe
Laser-cut stainless steel brackets
Silicone couplers and reducer
The filter housing includes a high-flow filter, an aluminum cap, laser-cut brackets, and the carbon pod itself. The carbon pods wrap around the reverse-mounted filter and gently shape the airflow to the intake tubes. This gradual reduction in cross-sectional area mimics the Venturi effect, where airflow accelerates while maintaining laminar conditions.
Carbon fiber intake duct
The duct was designed to have the maximum internal volume possible within the given engine bay geometry. This ensures that the filter housing can draw air with minimal restriction.
The intake tubes are also made of 100% prepreg carbon fiber. Each tube has an internal diameter of 88 mm – the stock tube is only 77 mm. This enlarged diameter allows the turbo to operate with less restriction and allows even larger/hybrid turbos to perform even better. The tubes smoothly transport airflow to the turbo, ensuring there are no sharp or sudden bends. The smooth bend geometry maintains laminar flow from the filters to the outlets.
The combined system ensures that airflow remains full and consistent to the turbo, minimizing the occurrence of turbulence. The following flow simulation shows how smooth and full the flow is inside the inlet tubes before the turbo. There is some circulation in the duct as expected, but once the flow enters the tube, it is attenuated, allowing the turbo to operate more efficiently.
