DISCONTINUED

Eventuri’s Carbon Fiber Intake System for 22+ Golf R and 22+ S3 is produced to excellently squeeze in more horsepower. The material made for this upgrade is prepreg carbon fiber, designed to withstand high heat and large volumes to offer the highest flow rate possible to maintain ambient air in the system. Each component is designed to provide the turbo with a smooth and free-flowing path.

The restrictive stock 73mm diameter inlet tube is replaced with a larger 94mm diameter intake tube. The filter has an outer diameter of 192mm or 7.5″ with a filtration surface area of over 110,000mm^2. The patented Venturi housing is designed to provide the maximum internal volume possible for the Golf engine bay's space available and provide a laminar flow to the turbo tube.

They have lifted the front of the duct to now have an extra opening behind the hood which is equivalent to an extra 7″ diameter hole for the intake to draw from. The overall system unleashes more gains while keeping the intake temperature at a minimum.

The Eventuri Difference

The 2.0 TFSi Generation 4 Eventuri system uses their Patented Carbon fiber Housings which provide an aerodynamically efficient airflow path from the filter to the turbo tubing. Not just another cone filter with a heat shield but a unique design that invokes the Venturi effect.

Dyno Testing

The MK8/8Y Golf R & S3 Intake has been independently tested by a reputable tuner in the UK, Regal Autosport. They tested an MK8 Golf R in stock form and also with a Tuning Box. Tests were done on the same day back to back with the stock airbox tested first and then the Eventuri fitted. No other changes were made to the car. The first graph shows the results using a stock map. As can be seen, there is a measurable gain throughout the RPM range of up to 12hp. This gain even on a stock car is noticeable on the road with better throttle response and quicker acceleration. The second graph shows results when using a tuning box which increases the flow demand from the intake system. The tuning box was used for both the stock airbox and the Eventuri intake without any changes between the tests. With a higher flow demand, the stock airbox presents a higher restriction to the turbo as can be seen by the significant gain achieved with the Eventuri fitted. They now have higher gains across the RPM range of up to 20hp and 30Nm, which is even more noticeable on the road. They expect gains to be even higher with higher states of tune.

CARBON DUCT

The duct channels ambient air from the slam panel area to the filter housing. It fits inside the OEM slam panel area and smoothly transitions to the circular filter housing shape. In order to ensure a good seal against engine bay heat - it also has a flexible rubber edging around the opening which presses against the filter housings creating the desired seal yet allowing the housing to move with the engine. Since this was designed to support high power builds, Eventuri found that the stock openings in the slam panel could cause a restriction at high flow demand. So they lifted the top surface of the duct and created an opening above the slam panel which is able to draw in cold air from behind the hood shut. This extra opening is equivalent to a hole with a diameter of over 7" and removes the restriction of the stock cold air feed. The duct was designed to have the maximum internal volume possible within the given geometry of the engine bay. This ensures that the filter housing is able to draw with minimum restriction.
