Eventuri Audi RS4 B9 Carbon Fibre Intake System

Developed in consultation with RS4 enthusiasts, the Eventuri Carbon Fibre Intake System addresses a genuine challenge on this platform: the B9 RS4's 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 instead of settling for that compromise.

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 back-to-back dyno testing - same day, bonnet closed, no other modifications - showed genuine gains of 11-16hp and 12-17ft-lb at the wheels, spread across a large portion of the rev range rather than concentrated at peak.

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-proven gains - 11-16hp and 12-17ft-lb across a wide rev range, verified back-to-back
• 100% pre-preg carbon fibre construction - genuinely insulates against engine bay heat
• Bespoke Generation 2 filter - aerodynamically efficient airflow path to the inlet tubes
