With the 8V RS3 Gen 2 and TT RS 8S widely used as the platform of choice for serious high-power builds, Eventuri developed this Stage 3 intake system specifically to support projects exceeding 1000whp — not just a mild refresh over a standard intake. A purpose-designed 210mm (8.3") filter with over 130,000mm² of filtration area sits within a patented Venturi housing that maximises internal volume for the RS3's confined engine bay, feeding a 103mm (4") carbon tube with a smooth curve straight to the turbo inlet.
The duct itself has been lifted at the front to create an extra opening behind the hood - equivalent to an additional 7" diameter hole for the intake to draw from - while remaining fully sealed against the front slam panel to keep intake temperatures at a minimum. Flow bench testing confirmed the complete system flows 840 CFM at 28" H2O versus 530 CFM stock. Independent dyno testing showed 15-18hp and 19-23ft-lb on stock turbo cars, climbing to 25-30hp and 20-24ft-lb on hybrid turbo setups, with V-Box testing showing 60-130mph acceleration improved as well.
Please note: this intake removes the OEM filtration system and, per manufacturer/retailer guidance, is intended strictly for closed track events and off-road use - it is not CARB or EPA certified. Check your local road-legal requirements before fitting.
