Eventuri carbon intake system for Audi B9 RS4/RS5

Performance increase: 13-17hp, 15-20ft lbV box
Acceleration: 60-130mph reduced by 0.5 seconds

The Audi B9 RS4/RS5 Eventuri intake system is designed to give the turbo a less restrictive airflow while ensuring low inlet temperatures. The RS5/RS4 engine compartment is very susceptible to heat build-up, so simply using an open filter system would result in better airflow at higher inlet temperatures. That's why we completely redesigned the airflow from the turbo intake to the front grille with a highly efficient, sealed system. The stock restrictive airbox and flexible plastic inlet tube have been replaced with our patented Venturi filter housing and a smooth transition duct system. The coiled fabric inlet tube is replaced with our Venturi housing and integrated full carbon tube, resulting in a smoother airflow as it enters the turbo inlet tube. The resulting performance improvements and aesthetics are industry-leading for this platform.Available with or without the optional air intake in real carbon fiber.The improvements come for a combination of reasons: 1) The closed system keeps the IATs low - especially with the front air scoop that Air is pushed into the system. 2) The venturi housing ensures a smooth transition from the filter to the intake pipe without friction. This helps the turbo run more efficiently by maintaining laminar flow in the intake path. 3) The entire system is made of pure pre-preg carbon fiber, which is excellent for thermal insulation.

The carbon housing encloses the rear-mounted filter and gently shapes the air flow downwards to the turbo pipe, which has the same diameter as the turbo inlet. This is a key feature of the intake concept, where we have eliminated the requirement for a smooth transition to a coiled rubber hose between the intake and the engine. The filter housing and integrated pipe extend to the stock turbo pipe and by mounting on the engine, the entire filter housing moves with the engine. As the motor and filter housing moves under acceleration, it is able to maintain a seal to the duct through an expanding rubber profile mounted on the face of the duct. This gentle reduction in cross-sectional area causes the Venturi effect, where the Air flow is accelerated while maintaining laminar conditions. It can be viewed as a large funnel. Nice to see in the diagram showing the comparison between our patent pending design and an OEM intake system. Our custom-made filters support airflow through the housings and allow for a consistent velocity profile as the airflow exits the housings.Carbon main air duct with expanding sealThe duct directs ambient air from the blade to the filter housing. It also creates a sealed volume of ambient air in front of the filter from which the system can draw air at any time. The duct was designed to make optimal use of the volume available in the engine compartment. To ensure a good seal against engine compartment heat, the duct also features a flexible rubber rim around the openings that press against the filter housing and OEM front duct, creating the desired seal while allowing the housing to move with the engine. To further improve airflow, we have an additional opening at the back of the duct in the cold area of ​​the engine compartment
