The Audi RS5 Eventuri intake was developed after consultation and support from RS5 enthusiasts. Eventuri have completely re-engineered the inlet track from the ducts to the filters and the inlet tubes. The restrictive stock airboxes and duct feeds have been replaced with a highly efficient system with smooth transitions to allow the airflow to remain full and laminar. The resulting performance gains, sound and aesthetics are industry leading for this platform. The RS5 Eventuri system uses our Patent Pending Carbon fibre Housings which provide an aerodynamically efficient airflow path from the filters to the throttle bodies. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect.
The filter housings comprise of the high flow filters, aluminium cowls, V-Band clamp, laser cut brackets and the carbon pods themselves. The carbon pods shroud the reverse mounted filter and smoothly shape the airflow down to the intake tubes. This smooth reduction in cross sectional area invokes the Venturi effect where the airflow accelerates whilst maintaining laminar conditions. It can be thought of as a large velocity stack.
The ducts channel ambient air from the scoops to the filter housings. They fit inside the OEM ducting system and smoothly transition to the circular filter housing shape. In order to ensure a good seal against engine bay heat - the ducts also have a flexible rubber edging around the openings which press against the filter housings creating the desired seal yet allowing the housings to move with the engine. These geometrically complex pieces are a key part of their B8 design. Eventuri intake tubes are again crafted from 100% prepreg carbon fibre. Each tube has an integrated breather tube insert which is CNC machined from aluminium. The tubes smoothly carry the airflow to the throttle bodies by ensuring there are no sharp or sudden bends. The smooth bend geometry ensure laminar flow is maintained from the filters to the exits
The final carbon components in this system are the front scoops - essential to direct ambient air to the ducts and then to the filters. The scoops were designed with a constant bend radius for maximum efficiency in directing the incoming air to the duct openings. They allow the inlet air temperatures to be as low as possible and increase the rate of drop in IATs after the system is heat soaked during a standstill.
The heat shields serve two purposes - to deflect heat from the exhaust manifolds and to provide a mounting surface for the housings. Laser cut from stainless steel, the shields provide a strong mounting point to secure the housings to. Furthermore, by using a class leading reflective material on the reverse face, the shields effectively block radiant heat generated by the exhaust manifolds thus reducing the heat soak onto the carbon components. All the components come together in the engine bay to produce a genuine improvement in the driving experience as well as providing an incredible visual display of form and function in complete harmony.
