By replacing the OEM airbox with our Patent Pending Venturi housing we have ensured that the airlfow remains as laminar as possible. Furthermore, the addition of a true cold air feed by adding a scoop to the front grill results in the lowest possible inlet air temperature. The result is an optimised intake system which delivers noticeable performance gains consistently. The Eventuri Difference The Audi S1 system uses our Patent Pending Carbon fibre Housing which provides an aerodynamically efficient airflow path from the filter to the turbo tube. Not just another cone filter with a heat shield but a unique design which allows airflow to remain laminar and thus improve the turbo efficiency. PerformanceProduct DetailsInstallation GuidePerformance The standard airbox is cuboid in shape which gives rise to turbulence and increases the drag on the turbo as a result. The transition from the rectangular air filter to the round turbo inlet gives rise to inefficiencies in the flow path which are addressed with our Venturi housing system. The following dyno graphs show the before and after results on a Golf 7 R (same engine as the Audi S1) which already had a remap. So both the stock airbox and the Eventuri were tested with the same remap in place. All tests were carried out back to back on the same day with the BONNET CLOSED ON ALL OCCASIONS. Dyno testing was carried out by Awesome GTI in the UK on their own C8 RS6 equipped with an aftermarket OPF back exhaust. They tested the car with the stock map and also their own stage 1 remap. They ran the car 4 times in 4th gear with the stock airbox and then swapped over to the Eventuri while the car remained on the dyno. The car was then run again in 4th gear 4 times. Testing was all done on the same day and no other changes were made. The graph below shows the highest power from the stock airbox vs highest power run from the Eventuri intake. Both were the first dyno pulls with subsequent pulls reducing in power due to heat soak. As can be seen below the intake provides a significant gain in performance throughout the RPM range with the stock map and more so with the stage 1 remap. The highlighted point shows the highest gain in the RPM range of 23hp at the wheels. Product Details Part Numbers: EVE-S1-CF-INT : Audi S1 2.0 TFSI Black Carbon intake The Eventuri Audi S1 intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. Here are the details for each component and the design ethos behind them: Each intake system consists of: Prepreg Carbon Fibre Venturi Housing High Flow generation 2 Air Filter Aluminium Cowl for smooth airflow entry Laser Cut Intake Duct Laser Cut Cold Air Laser Cut Stainless Steel Brackets Carbon Intake Housing The filter housing comprises of a high flow filter, aluminium cowl, laser cut bracket and the carbon pod itself. The carbon pod shrouds the reverse mounted filter and smoothly shapes the airflow down to the intake tube. This smooth reduction in cross sectional area invokes the Venturi effect where the airflow accelerates whilst maintaining laminar conditions.

Further details can be read in the Technology page. Our bespoke filters aid the airflow moving through the housings and allow for an even velocity profile as the airflow exits the housings.

It effectively blocks the heat from the engine bay and ensures that the air intake temperatures remain as low as possible. Intake Scoop The final part of the intake is the aluminium scoop which sits behind the grill and directs ambient air into the duct.
