Eventuri Audi RSQ3 F3 Intake System

Eventuri Audi RSQ3 F3 Intake System is a high-performance carbon fiber intake system developed specifically for the Audi RSQ3 F3 and RSQ3 Sportback 2019+, with a focus on maximizing airflow while maintaining low intake temperatures.

Originally developed for high-power builds on the Audi RS3 platform, Eventuri adapted the system for the RSQ3 F3 while retaining the same engineering philosophy: provide the turbocharger with the smoothest and least restrictive airflow path possible while keeping the intake system sealed from engine-bay heat.

One of the most significant features is the 103 mm internal diameter intake tube, which is just over 4 inches in diameter. The tube uses a smooth curvature from the filter housing all the way to the turbo inlet, reducing abrupt transitions and helping maintain a consistent airflow path into the turbocharger.

The system uses a purpose-designed High-Flow Dry Cone Filter with an outer diameter of 210 mm and a filtration surface area exceeding 130,000 mm². The large filter provides substantial filtration area while allowing the intake system to support high airflow demand from both stock and upgraded turbocharger configurations.

At the heart of the system is Eventuri's Patented Carbon Fiber Venturi Filter Housing. The reverse-mounted filter is enclosed by the carbon housing, which progressively reduces the cross-sectional area toward the intake tube. This creates the Venturi Effect, accelerating the airflow while maintaining a smoother, more laminar flow profile into the turbocharger.

Eventuri also designed the intake duct specifically around the RSQ3 F3 engine bay. Rather than relying solely on the factory air entry, the front section of the duct is raised to create an additional opening behind the hood. Eventuri states that this additional opening is equivalent to approximately a 7-inch diameter hole, allowing the intake to draw substantially more ambient air.

The entire system uses a sealed design to minimize the amount of hot engine-bay air reaching the filter. This is particularly important on the 2.5 TFSI platform, where maintaining low intake temperatures becomes increasingly important during high-load driving and high-power applications.

In Eventuri's flow-bench testing, the stock intake flowed approximately 530 CFM, while the Eventuri system achieved 840 CFM at 28 inH₂O. This represents a substantial increase in the system's airflow capability.

For performance reference, Eventuri reports 15–18 hp and 19–23 ft-lb of additional output on an RS3 with the stock turbo, while an RS3 equipped with a hybrid turbo showed 25–30 hp and 20–24 ft-lb gains. These figures are from the RS3 development/testing platform rather than a direct RSQ3 dyno claim, so they should be treated as reference data rather than RSQ3-specific power figures.

The Eventuri Audi RSQ3 F3 Intake System is therefore designed not simply as a larger filter replacement, but as a complete airflow system combining large filtration area, 103 mm intake tubing, patented Venturi housing, dedicated carbon ducting and sealed cold-air delivery.
