The Audi RS5/RS4 Eventuri intake was developed after consultation and support from RS5 enthusiasts. We have completely re-engineered the inlet track from the ducts to the filters and the inlet tubes. The restrictive stock airboxes and duct feeds have been replaced with a highly efficient – fully sealed system with smooth transitions to allow the airflow to remain full and laminar. The resulting performance gains, sound and aesthetics are industry leading for this platform.
The Eventuri Difference
The RS5/RS4 Eventuri system uses our Patent Pending Carbon fibre Housings which provide an aerodynamically efficient airflow path from the filters to the throttle bodies. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect.

Below is an independent dyno graph showing the comparison between the Eventuri and the stock airboxes on a standard RS5. As you can see, power is increased through a large portion of the rpm range not just at the peak. 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 car was tested firstly with the stock intake - hood closed. We then left the car on the dyno and installed the Eventuri. The car was then run again - hood closed. Several runs were carried out with both configurations to get a consistent result. Since dyno figures vary between runs - for fairness we chose to publish figures using the highest stock run VS highest Eventuri run. Here you can see the 2 best runs with both configurations.
We could have shown the highest figure achieved with the Eventuri VS the lowest achieved with the stock setup, however this would not be a fair comparison. Just to illustrate the variation, here is the graph showing highest Eventuri VS lowest stock which was recorded on the day showing a gain of over 32hp at the wheels.
Here is another graph showing the difference between the stock airboxes and the Eventuri intake system - this time on a B8 RS4. Dyno runs were done on the same day and the car remained strapped to the dyno during installation to ensure strap tensions were the same for both tests. Here we can see a considerable gain in both torque and power - with 25ft-lb toque gained in the midrange and 25hp gained before peak rpm.
