Audi Porsche Black Carbon Intake - Eventuri EVE-4V8TT-CF-INT

Our 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 we 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.

*Gains measured can vary with different ECU tunes.

The Eventuri 4.0TFSI V8 intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. We use 100% pre-preg carbon fiber with no fiberglass which means we can achieve a smooth internal surface to maintain smoother airflow. Here are the details for each component and the design ethos behind them:

Each intake system contains the following

• Enlarged Carbon Fiber AIrbox Lid
• Carbon Fiber Flow Collector
• (2) Thermoplastic Turbo Inlets with Dimpled Inner Surface
• (2) Bespoke High Flow Dry Cone Filters
• Custom Flexible Hoses
• CNC Machined Breather Ports and Reinforcement Rings
