Eventuri Audi 8V Gen 2 RS3 / 8S TTRS Black Carbon Stage 3 Intake System

The Eventuri Black Carbon Stage 3 Intake System for the Audi 8V Gen 2 RS3 and 8S TTRS has been engineered to support extreme power levels while maintaining low intake air temperatures and uncompromised airflow efficiency. Developed for high-performance and hybrid turbo applications, this system delivers the flow capacity required for builds exceeding 1000whp while retaining OEM-level fitment and drivability.

At the core of the system is Eventuri’s patented carbon fiber Venturi filter housing, maximized in internal volume to suit the confined RS3 engine bay. The housing works in conjunction with a bespoke 210mm outer diameter high-flow dry filter, providing over 130,000mm² of filtration surface area. This combination promotes laminar airflow into the 103mm internal diameter intake tube, creating a smooth, restriction-free path to the turbocharger.

The intake tube maintains a consistent 103mm internal diameter with optimized curvature from the filter housing to the turbo inlet, allowing the turbo to operate with reduced drag and improved efficiency. The sealed carbon inlet duct draws ambient air from the factory slam panel location while also introducing an additional high-pressure feed from beneath the hood, effectively adding the equivalent of a 7-inch secondary air entry.

Constructed entirely from 100% prepreg carbon fiber with no fiberglass, the system achieves a smooth internal surface to further enhance airflow quality. A dedicated heat shield with gold reflective backing protects the intake from radiant engine heat, ensuring stable intake temperatures even under sustained high-load conditions.

Flow bench testing demonstrates the capability of the system, increasing airflow from 530 CFM with the factory intake to 840 CFM at 28" H2O. Independent performance testing shows gains of 15–18hp and 19–23 lb-ft on stock turbo vehicles, with hybrid turbo applications realizing increases of 25–30hp and 20–24 lb-ft.

Every component is designed to function as part of a complete system, providing the turbocharger with the highest possible airflow while maintaining thermal efficiency for consistent, repeatable performance.
