The S3 8Y intake is a complete redesign of the stock intake all the way to the turbo inlet. Taking cues from our RS3 intake, we have maximised usage of the available space to create an intake that can cater for all power levels from stock to high power builds with hybrid or full-frame turbos. This intake system has been developed to offer the highest possible flow rate whilst maintaining the lowest intake temperatures possible. Each component has been 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 tube intake tube. The filter itself has an outer diameter of 192mm or 7.5″ with a filtration surface area of over 110,000mm^2. The patented Venturi housing has been designed to provide the maximum internal volume possible for the S3 engine bay space available and provides laminar flow to the turbo tube. Finally the duct seals the filter opening to the front slam panel but is not restricted by just the stock entry feed. We have lifted the front of the duct to now provide an extra opening behind the hood which is equivalent to an extra 7″ diameter hole for the intake to draw from. The resulting system can significantly outflow the stock airbox while keeping intake temperatures at a minimum with the sealed design.

The Eventuri Difference

The S3 8Y Eventuri system uses our 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 which invokes the Venturi affect. You can read more about the housing design and how it works here.


Our S3 8Y Intake has been independently tested on a MK8 Golf R by a reputable tuner in the UK, Regal Autosport. They tested a 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. We now have higher gains across the RPM range of up to 20hp and 30Nm, which is even more noticeable on the road. We expect gains to be even higher with higher states of tune.

Flow Bench Testing

We conducted flow rate tests using a Superflow SF-1020 to measure the maximum flow rate possible at a pressure drop of 28” H2O. Tests were done on the same day in controlled conditions using the same test jig for each system. We tested our full intake system against the stock airbox system for both the R and GTi variants. The results show an increase of maximum flow by an additional 72% for the Golf R system. Importantly this has been achieved with a sealed intake system so the intake temperatures will also be maintained at a minimum.

The gains are from a combination of reasons:

1) The sealed system keeps IATs low - the Audi engine bay can get heat soaked very quickly so an open cone filter will cause an increase in IAT values resulting in a loss of performance.

2) The Venturi housing provides a smooth transition from the filter to the intake tubes which are both matched to an internal diameter of 94mm. This helps the turbo to run more efficiently.

3) The entire system is constructed from pure pre-preg carbon fibre which is great at insulating from heat and has smooth internal surfaces as opposed to fibreglass which will have sharp resin lines present.
