Audi RS3 Gen 2 / TTRS 8S intake for DAZA and DWNA Engines

The Eventuri Stage 3 intake system for the 8V RS3 Gen 2 and TTRS 8S is engineered to deliver maximum airflow while maintaining the lowest possible intake temperatures. Designed to support high-powered builds, this system flows 840 CFM—a 58% improvement over the restrictive stock airbox—while the sealed design prevents engine bay heat soak that compromises performance.

Each component has been meticulously designed to provide the turbo with a smooth and free-flowing path. The patented Venturi housing uses aerodynamic principles to accelerate airflow while maintaining laminar conditions, eliminating turbulence that plagues conventional cone filter setups.

Key Features:

• 103mm internal diameter intake tube with smooth curvature minimizing pressure drop
• 210mm diameter bespoke high-flow cone filter with 130,000mm² filtration surface area
• Patented carbon fiber Venturi housing invoking laminar flow principles
• Sealed design with elevated hood scoop providing equivalent to 7" diameter extra cold air entry
• 100% pre-preg carbon fiber construction eliminating fibreglass resin imperfections
• Gold reflective heat shield protecting carbon tube from turbo radiation and convective heat
• Compatible with both DAZA and DWNA engines (2019 OPF versions supported)
• ISO-tested dry cone filter maintains OEM filtration standards

Performance Notes:

• +15-18hp on stock turbo RS3; +25-30hp with hybrid turbo
• +19-23ft-lb torque (stock turbo); +20-24ft-lb (hybrid turbo)
• Flow bench verified 840 CFM at 28" H2O versus 530 CFM stock airbox
• Supports over 1000whp on full frame turbo builds
• Enables lower boost requirements compared to competing systems

Includes:

• Carbon fiber Venturi filter housing with 103mm outlet
• Bespoke high-flow dry cone filter (210mm OD)
• Carbon fiber inlet duct with flexible rubber seal
• Smooth-curve carbon fiber intake tube (103mm ID)
• Heat shield with gold reflective backing and stainless steel brace
• OPF (DWNA) breather adapter for 2019+ applications
• Laser-cut stainless steel mounting brackets
• Silicon breather hose and couplers
• Installation guide and all required hardware

Maximum airflow. Minimum temperatures. Unlimited potential for the RS3 8V and TTRS 8S.
