Performance increase: 16-25 HP, 15-22 foot-pounds
The 2.0 TFSi system uses our patent-pending carbon fiber housing that provides a more efficient path for aerodynamically efficient airflow 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 2.0 TFSi system uses our patent-pending carbon fiber housing that provides a more efficient path for aerodynamically efficient airflow 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 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 optimised intake system that consistently delivers significant performance gains.
The standard airbox has a cubic shape that creates turbulence and therefore increases turbo drag. It also draws 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 hot engine compartment heat. Furthermore, 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 graphs show the before and after results on a Golf 7 R 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.
Independent Dyno Test BR Performance from Belgium has tested this intake on a stage 1 tuned Clubsport using their in-house dynamometer and the intake achieved a gain of 19bhp.
Single VS Twin Duct During the development of our system we designed and tested both the single duct and an extended twin duct version. duct.
The Eventuri Golf 7 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:
Carbon Filter Housing & Intake Duct
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 up to the intake pipe. This gentle reduction in cross-sectional area is reminiscent of 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 normal intake system. More details can be read on the Technology page. The duct channels cold air from the shutter panel opening to the filter. By designing the duct to transition smoothly from the rectangular opening at the front to the circular filter opening, it allows the airflow to remain as direct and smooth as possible.
PATENTED TECHNOLOGY
Our patented filter housing has a smooth reduction in cross-sectional area as it wraps around the filter and tapers towards the tube. This geometry is reminiscent of the Venturi effect, where airflow accelerates while maintaining laminar conditions. It can be thought of as a large velocity stack - below is a diagram showing how our patented design compares to a standard intake system. Our custom filters help the airflow move through the housings and allow for a smooth velocity profile as the airflow exits the housings. More details can be found on the Technology and Filters pages.
Single Flue VS Double Flue
During the development of our system we designed and tested both the single flue and an extended double flue version: Testing showed that the dual duct did not produce more horsepower, 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 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 grill to enter the filter housing. A dyno chart comparing the single and dual ducts can be viewed on the Performance tab.
Cold Air Intake
A key feature of our system is the addition of a scoop in the grille that opens a direct path for cold air to enter the duct. When the hood is closed, this prevents a direct air supply to the duct and the only path for cold air to enter is the small gap between the closed hood and the top of the grille, or the small slots on the other side of the grille. This means that the intake will draw some air from the hot area of the engine bay. With our scoop system, when the car is moving, there is a very small chance of hot air entering the intake and therefore the intake temperatures are lower than the OEM airbox. Here is a thermal imaging video of the engine bay showing how cool the intake system is after a good drive.
