Eventuri’s 4.0TFSI V8 EA825 intake is a ground-up redesign and optimisation of the entire air inlet track. Every component including the lid has been developed to allow the V8 twin turbos to pull in air with less drag resulting in industry-leading performance gains. The stock airbox lid itself creates a restriction on the size of the flow collector which feeds the inlets from the filters. So Eventuri increased the height of the central section of the lid to allow for a larger flow collector and larger cone filters to be used. This removes the inherent restriction and sets our intake apart from the rest of the field who by utilising the stock lid must also use a restricted collector and filtration media. The turbo inlets are up to 43% larger in cross-sectional area than stock and are designed with an advanced dimpled inner surface to reduce frictional losses between the flow and the wall boundary. By allowing a “cushion” of air at the wall surface, airflow is able to move through the inlets at higher flow rates with reduced pressure loss. This allows the turbos to draw air with less resistance and therefore reduce the wastegate duty cycle resulting in higher overall performance.

Performance Gain Stock Map: 14-20hp, 17-21ft-lb
Performance Gain Stage 1 Map*: 25-28hp, 20-23ft-lb

*Gains measured can vary with different ECU tunes.

This intake has been independently dyno-tested by Eurocharged Canada. Tests were done back to back against the stock airbox and several runs were taken with each configuration. The dyno results show a consistent gain throughout the RPM range which can be attributed to the turbos reaching peak boost earlier and with a lower wastegate duty cycle due to the higher efficiency of the intake system. The first graph shows the results on a completely stock vehicle with only the intake being changed between runs. The second graph shows an RSQ8 which had a stage 1 tune and drop-in filter as the baseline run. Then the intake was changed leaving the tune as it was. The performance gains on both vehicles translates on the road to increased part throttle and full throttle response with the car pulling much more eagerly to the redline.
