EVENTURI Carbon Intake System S3 8Y

The Venturi intake system for Audi S3 8Y has been developed as a high-performance solution for all tuning levels – from stock to high-power configurations.

The system uses 100% pre-preg carbon, without fiberglass, which allows for an exceptionally smooth internal surface. This is crucial for maintaining laminar airflow and maximum efficiency.

What the system includes

• Patented Carbon Venturi Filter Housing with 94mm outlet

• Specially developed high-flow dry cone filter

• Carbon full-width intake duct

• Silicone turbo hose with 94mm inlet

• Machined breather adapter

• Laser-cut stainless mounting brackets

Patented Venturi Technology

The carbon housing encases the reverse-mounted filter and smoothly reduces the cross-section towards the turbo tube. This smooth geometry creates a Venturi effect, where air accelerates without disturbing the laminar flow.

It can be thought of as a "large velocity stack" but integrated into a fully sealed system.

Specially Developed Filter

To achieve maximum flow, Eventuri developed a new filter element:

• 192mm (7.6″) outer diameter

• Up to 900 CFM at 28″ H₂O (with 4″ housing opening)

• ISO tested filtration to OEM standard

• Dry filtration

• Conical geometry, aiding the Venturi effect

Carbon Intake Duct

The duct directs cold air from the slam panel area to the filter.

• Smooth transition to the round housing

• Rubber seal against heat from the engine bay

• Allows engine movement without breaking the seal

For high-power configurations, standard openings can create a restriction. Therefore:

• Raised top surface

• Additional inlet behind the cover

• Equivalent to an opening over 7″ diameter

This completely eliminates the restriction of the factory cold air intake.

94mm Silicone Turbo Hose

The factory 73mm hose is replaced with a 94mm silicone hose, which represents:

• Over 60% increase in cross-section

• Maximum diameter retention to the turbo inlet

• Smooth tapering to the stock turbine
