Eventuri Porsche Cayenne 2025+ Turbo S, GTS, GT 4.0 TFSI Intake

Our 4.0TFSI V8 EA825 intake has now been updated to fit the 2025 facelift Cayenne Turbo variants. Every component including the lid has been developed to allow the V8 twin turbos to pull in air with less drag resulting in noticeable improvements to the power delivery. 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 for maximum volume. The extra volume enables the turbos to respond faster resulting in a noticeable improvement in throttle response.

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 fibreglass 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 consists of:

✓ Enlarged Carbon Fiber Airbox Lid
✓ Carbon Fiber Flow Collector
✓ 2 x Custom EPDM Inlet Hoses
✓ 2 x Bespoke High Flow Dry Cone Filters
✓ CNC Machined Reinforcement Rings

ENLARGED AIRBOX LID

The first constraint we had to overcome in order to dramatically increase the overall volume of the intake was the airbox lid. The stock lid leaves a shallow opening for the flow collector and also restricts the filtration medium being used. By creating a raised portion in the middle of the lid we are able to create more space for a larger flow collector and also for larger filters. The lid is made from prepreg carbon fibre and uses the same mounting points as the stock lid.

CARBON FLOW COLLECTOR & FILTERS

Directing the airflow from the filters to the turbo inlets is the flow collector. The stock one is constricted in size due to the stock lid but having removed that restriction, we were able to dramatically increase the volume of our version. In addition, this also gave us the freedom to replace the stock filter with higher flowing cone filters which also have a larger total surface area.

TURBO INLETS

The biggest restriction in the stock system are the turbo inlets. The stock inlets maintain a small cross sectional area from the turbos all the way to the airbox. We have redesigned the inlets to increase in size immediately after the turbos. This creates a larger volume of captured air which the turbos can use with minimal drag and this results in an improved throttle response. The new inlets also allow for engine movement without causing turbulent flow.

The complete system comes together to provide an intake which improves on the stock airbox in performance, aesthetics and sound.........
