The Eventuri intake system for the 4.0 TFSI V8 EA825 is engineered from the ground up to maximize airflow and performance. It features both technical finesse and superior craftsmanship, delivering substantial power gains and enhanced response.

Design & Functionality:

The raised carbon lid enables a larger flow collector and filters, dramatically reducing intake restriction. Turbo inlets are increased by up to 43% in cross-sectional area and are engineered with a dimpled internal surface that reduces friction by maintaining an air “cushion,” enabling higher airflow with reduced pressure loss.

Dyno-Tested Performance:

Independent dyno testing by Eurocharged Canada shows strong, consistent gains across the RPM range—on both stock and Stage 1 tuned RS Q8s. Despite unchanged ECU tuning, response and throttle engagement improve dramatically.

Benefits at a Glance:

• Smoother, faster turbo spool with reduced wastegate duty cycle
• Improved part- and full-throttle responsiveness up to redline
• Enhanced engine sound, performance, and visual appeal

Advanced Engineering:

Finely tuned via R&D and CFD simulations, the dimpled inlets function by promoting air slip along tube walls, leading to higher velocity flow. This level of precision would be impossible with traditional manufacturing methods.

Scope of Delivery:

• 1x Full intake system consists of:
  • Enlarged Carbon Fiber AIrbox Lid
  • Carbon Fiber Flow Collector
  • 2 Thermoplastic Turbo Inlets with Dimpled Inner Surface
  • 2 x Bespoke High Flow Dry Cone Filters
  • Custom Flexible Hoses
  • CNC Machined Breather Ports and Reinforcement Rings
