Wheels\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Audi B9 RS4\/RS5 Eventuri intake was developed to give less restrictive airflow to the turbo whilst maintaining low inlet temperatures. The RS5\/RS4 engine bay becomes heat soaked very quickly so simply having an open cone system would result in better airflow but with higher inlet temperatures. We therefore completely re-engineered the inlet track from the turbo inlet pipe to the front grill with a highly efficient sealed system. The restrictive stock airbox and flexible plastic inlet pipe have been replaced with a Venturi filter housing and a duct system with smooth transitions. Furthermore, by removing the convoluted stock inlet pipe and replacing it with our one-piece Venturi housing and solid tube, the airflow is much smoother as it enters the turbo inlet tube. The resulting performance gains and aesthetics are industry leading for this platform.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Eventuri Difference\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe B9 RS4\/RS5 Eventuri system uses our Patent Pending Carbon fibre Housings with our bespoke Gen-2 filter which provide an aerodynamically efficient airflow path from the filter to the inlet tubes.

The car had no other modifications. As you can see, power and torque are increased through a large portion of the rpm range. This translates on the road to increased part throttle and full throttle response with the car pulling much more eagerly to the redline. The testing was done on the same day back-to-back and temperatures were monitored to ensure consistency. The bonnet was closed for all runs.\u003c\/p\u003e\n\u003cp\u003eThe gains are from a combination of reasons:\u003c\/p\u003e\n\u003cp\u003e1) The sealed system keeps IATs low – especially with the front air scoop which forces air into the system.\u003c\/p\u003e\n\u003cp\u003e2) The Venturi housing provides a smooth transition from the filter to the intake tube with no convoluted rubber section.
