EVENTURI Carbon Intake System Stage 3 Audi RS3 8V

For the Audi RS3 8V facelift and Audi TT RS 8S platforms, which are increasingly being built as high-power projects, Eventuri has developed a revolutionary Stage 3 carbon intake system, capable of supporting configurations over 1000 whp.

This system is designed to provide maximum flow with minimal inlet temperatures, with each component optimized for a smooth and unobstructed airflow path to the turbo.

Engineering Highlights

• 103 mm (4″) inner diameter intake pipe

• Smooth geometry from filter to turbo inlet

• Specially developed filter with:

  • 210 mm (8.3″) outer diameter

  • Over 130,000 mm² filtration area

• Patented Carbon Venturi Housing for laminar flow

• Sealed duct to the front panel + additional inlet behind the cover
  → equivalent to an additional 7″ opening

The result:
840 CFM at 28″ H₂O, maintaining low IAT thanks to the fully sealed design.

The Eventuri Difference

The system uses patented carbon housings that create an aerodynamically efficient air path – not just a conical filter with a heat shield, but a true Venturi configuration.

This means:

• Higher flow

• Lower turbulence

• Better efficiency at high boost levels

• OEM+ integration into the engine bay

Flow Bench Tests

Tested with a Superflow SF-1020 at 28″ H₂O under controlled conditions.

Compared to the factory airbox system:

• Up to +58% increase in maximum possible flow

• Achieved with a sealed design that maintains low intake temperatures
