Eventuri Audi S5 B9 Carbon Fibre Intake System

The Eventuri Carbon Fibre Intake System addresses a genuine challenge on the B9 S5: the engine bay heat soaks very quickly, so a simple open cone filter setup would trade better airflow for worse intake temperatures. Eventuri's answer was to completely re-engineer the inlet track from the front grille all the way to the turbo inlet pipe with a fully sealed, highly efficient system rather than accepting that trade-off.

The restrictive stock airbox and flexible plastic inlet pipe are replaced entirely with a one-piece Venturi filter housing and solid duct system, eliminating the convoluted rubber section that disrupts airflow on the factory setup. A front air scoop actively forces cold air into the sealed system, so intake air temperatures stay low despite the enclosed design. Independent V-Box road testing showed 60-130mph acceleration reduced by almost 0.5 seconds - notably, a bigger real-world gain than the dyno figures alone suggest, since correct flow conditions at speed reveal more of the intake's benefit than a static dyno run does. Dyno testing itself confirmed 13-17hp and 15-20ft-lb.

Works with: Stock ECU and turbo - shares its core design with Eventuri's B9 RS4/RS5 intake, adapted for the S4/S5's specific tune.

Why Choose This Intake System

• Fully sealed, re-engineered inlet track - front grille to turbo inlet redesigned as one system
• One-piece Venturi housing and solid tube - eliminates the convoluted stock rubber inlet section
• Front air scoop - actively forces cold air into the sealed system, keeping IATs low
• Dyno and road-proven gains - 13-17hp/15-20ft-lb on dyno, up to 0.5s faster 60-130mph on the road
• 100% pre-preg carbon fibre construction - genuinely insulates against engine bay heat
• Bespoke Generation 2 filter - aerodynamically efficient airflow path to the inlet tubes
