The Eventuri Porsche 991.1 / 991.2 GT3 RS Carbon Intake System is engineered to increase airflow efficiency, expand flow capacity, and maintain consistently low intake air temperatures for the naturally aspirated 4.0L flat-six. Developed through extensive flow bench testing and real-world validation, the system replaces the factory airbox with a larger-volume sealed carbon assembly to provide a smoother and less restrictive path to the engine.
At the core of the system is Eventuri’s patented double Venturi filter housing, which allows airflow to transition through the filters with significantly reduced turbulence and drag compared to the OEM intake. By optimizing the internal geometry and maximizing the available space, the intake achieves a higher overall flow capacity while maintaining stable intake temperatures during repeated high-RPM operation.
Each bespoke high-flow dry filter features a large 192mm outer diameter and over 110,000mm² of filtration surface area, ensuring the engine receives the airflow required for peak performance without compromising filtration efficiency. The fully sealed carbon fiber construction minimizes heat soak while the smooth internal surface promotes laminar airflow to the throttle body.
The result is a measurable increase in power, improved throttle response, and a sharper induction character that enhances the GT3 RS driving experience while retaining OEM-level fitment and reliability.
