AUDI 8V S3
The Eventuri VAG 2.0 TFSi intake has been developed to provide the most efficient and direct airflow path to the turbo. By replacing the patent-pending OEM venturi housing and pairing it with a smooth duct, we have ensured that the airflow remains as laminar as possible. Additionally, the addition of a true cold air feed by adding a scoop to the front grille results in the lowest possible inlet air temperature. The result is an optimized intake system that consistently delivers significant performance gains.
Performance Increase: 16-25 HP, 15-22 ft-lbs

The Eventuri Difference
The 2.0 TFSI system uses our patent-pending carbon fiber housing that provides an aerodynamically efficient airflow path from the filter to the turbo pipe. Not just another conical filter with a heat shield, but a unique design that allows the airflow to remain laminar and therefore improve the efficiency of the turbo.
The standard airbox has a cubic shape that creates turbulence and therefore increases the drag of the turbo. It also sucks air from a duct that, despite extending across the entire grille, is actually only open on one side and this opening also faces the engine, so the airbox sucks in the hot heat from the engine bay. Also, when the bonnet is closed, the only direct path for cold air is from the small slots at the top of the grille (for Golf 7 variants).
The following dynamometer plots show the before and after results on a Golf 7 R (same engine as the Audi 8V S3) that already had a remap. So both the stock airbox and the Eventuri were tested with the same remap in place. All tests were performed back to back on the same day with the HOOD CLOSED AT ALL TIMES.
Single duct VS Double.
During the development of our system we designed and tested both a single duct version and an extended double duct version.
Testing showed that the dual duct did not produce more power, in fact we were unable to achieve the same results as our single duct design. This is because the single duct allows for the smoothest, most direct airflow path to the filter. With the scoop directly in front of the opening there is no chance for hot air to mix with the airflow. Also on the dual duct, the airflow must travel at a nearly 90 degree angle from the far side of the grill to enter the filter housing. Here is a dyno chart showing the results achieved with both duct designs.
The Eventuri Audi S3 intake system is made up of a series of components designed to perform a specific purpose and manufactured to the highest standards. Here are the details for each component and the design ethic behind them:
Each intake system consists of:
Housing and intake duct in carbon
The filter housing is comprised of a high flow filter, an aluminum cap, a laser cut bracket, and the carbon pod itself. The carbon pod wraps around the reverse mounted filter and gently shapes the airflow to the intake tube. This gentle reduction in cross-sectional area mimics the Venturi effect where the airflow accelerates while maintaining laminar conditions. It can be thought of as a large velocity stack - below is a diagram showing how our patent pending design compares to a typical intake system. More details can be found on the Technology page. The duct channels cold air from the baffle opening to the filter. By designing the duct to transition smoothly from the rectangular opening at the front to the circular opening for the filter, it allows the airflow to remain as direct and smooth as possible.
Testing showed that the dual duct did not produce more power, in fact we were unable to achieve the same results as our single duct design. This is because the single duct allows the smoothest, most direct airflow path to the filter and the cross-sectional area of the opening is not restrictive for this engine. With the scoop directly in front of the opening there is no chance for hot air to mix with the airflow. Also on the dual duct, the airflow must travel at a nearly 90 degree angle from the far side of the grille to enter the filter housing.
