Eventuri Carbon Fiber Air Intake Audi RS6, RS7 C7

The Audi C7 RS6/RS7 Eventuri intake sets a new standard for intake design on this platform. It was developed to achieve two goals - 1) Limit the turbo intake paths. 2) Maintain low intake temperatures. The first goal was achieved by providing each turbo with a separate filter and Venturi chimney to reduce air resistance and make the turbos work more efficiently. The second goal was accomplished by placing the filters in a carbon airbox and feeding them with an additional scoop behind the grille. The C7 RS6/RS7 engine bay has multiple heat sources from different directions, so a simple setup with open filters and shields would result in higher IAT values. Our carbon airbox housing is designed to maximize the available volume and block all heat sources. The resulting performance gain and aesthetics are industry-leading for the C7 RS6/RS7.

The Eventuri system for the C7 RS6/RS7 uses 2 Venturi connections on the filters that smoothly transition into the turbo pipes. These provide an aerodynamically efficient airflow path from the filters to the turbos. Not just a cone filter with a heat shield, but a unique design that invokes the Venturi effect and allows laminar flow through the pipes, reducing resistance on the turbos.

Each intake system consists of:

• Carbon fiber airbox housing
  
• 2 x high flow dual cone air filters
  
• 2 x carbon Venturi pipes with integrated tubes
  
• Carbon fiber intake duct
  
• Carbon fiber front spoiler
  
• Laser-cut heat shield with gold reflection
  
• Laser-cut stainless steel bracketry
  
• CNC-machined airbox mounts

This system has been extensively tested, both on the dyno and on the road. First, dyno tests were performed, showing an impressive gain of about 19 hp and 17 Nm of torque. This translates on the road to better throttle response and full throttle performance, with the car pulling much more eagerly to the redline. The tests were conducted on the same day consecutively and temperatures were monitored to ensure consistency. The car was first tested with the standard intake - hood closed. Then the car was left on the dyno and the Eventuri was installed. The car was then retested with the hood closed. Multiple runs were performed with both configurations to achieve consistent results.
