The Eventuri intake system for the Audi S4/S5 consists of several elements that fulfill precisely defined functions and are manufactured in accordance with the highest quality standards. Below you will find descriptions of individual components and an explanation of their operation.

Each intake system consists of the following components: • Venturi carbon casing with integrated pipe • 2nd generation high-flow filter • carbon internal intake duct • carbon air intake • high-quality silicone connectors and clamps in factory specifications • laser cut stainless steel handles • fastening elements, milled using CNC technology Carbon Intake Housing Assembly Carbon filter housing set

The set consists of a specially developed 2nd generation filter, a carbon housing shell and an integrated pipe. The shell houses a reverse-mounted filter and gently shapes the air stream flowing into the turbine inlet pipe thanks to the perfect fit in terms of diameter. This is a key issue in the design of the Eventuri intake, as it eliminates the need to use a twisted rubber pipe between the intake and the engine. The filter housing and integrated pipe connect directly to the factory turbine inlet pipe and because it is attached to the engine, the entire filter housing moves with the engine. Even with increased acceleration and traffic intensity of the engine and the filter housing, full tightness is maintained thanks to the use of an expandable rubber seal mounted on the front of the channel.

A gentle, gradual reduction in cross-sectional area causes the Venturi effect, i.e. acceleration of air flow while maintaining its layered (laminar) arrangement. The housing design resembles a trumpet-shaped intake pipe (velocity stack). Specially developed Eventuri filters support the air flow through the housing and enable even distribution of its speed when leaving the housing.

Carbon internal intake duct The internal channel has a geometrically complex structure and is a key element of the intake, directing air from the outside to the filter housing. The air collects in a closed space in front of the filter and is ready to pass further. The channel design makes maximum use of the available space in the engine compartment. To ensure tightness, protecting against high temperatures, flexible rubber rims are used around the holes, which press against the filter housing and the factory front channel. This creates a tight connection, which also allows the housing to move with the engine. To further improve the flow, an additional hole was used in the rear part of the channel, adjacent to the cold zone of the engine compartment.

Carbon air intake Another carbon element in this set is the front inlet, whose task is to direct the air flow to the intake duct and further to the filter.

The inlet has a constant bend radius for maximum efficiency in directing the airflow into the intake duct opening. It allows you to maintain a low intake air temperature and increases the level of air temperature reduction in the event of excessive engine warm-up while standing still.

Specially developed fastening elements To guarantee a perfect fit, Eventuri engineers spent a lot of time developing the fastening elements. All brackets and mountings have been specially developed for use on this vehicle. Each one is laser cut and powder coated for increased durability. Milled mounts attach to the mounts and press into the factory rubber mounts to which the factory intake system mounts. Thanks to this, the Eventuri intake fits like an original element.

All elements together contribute to a significant improvement of the driving experience, as well as to obtain extraordinary aesthetic values, which proves the perfect harmony of form and functionality.
