Porsche 991.1 / 991.2 GT3 RS Eventuri Carbon Fiber Intake

The Porsche GT3 RS intake has been designed to offer a more efficient flow path to the engine in comparison to the OEM airbox. Utilising our Patented Venturi Housing concept, airflow is able to negotiate through the filters with a much less tortuous path thus reducing the drag of the system. Furthermore by increasing the overall volume in the intake, the maximum flow capacity has also been increased. Using bespoke filters with an outer diameter of 192mm or 7.5″ boasting a filtration surface area of over 110,000mm^2 each, we have made maximum use of the available space. Intake air temperatures have also been minimised by ensuring a sealed system as well as using carbon fiber which has a low thermal conductivity coefficient across the wall thickness. The resulting system provides genuine performance gains and a noticeable improvement in throttle response.

INCLUDED COMPONENTS

Carbon Fiber Double Venturi Filter Housing

2 Bespoke High Flow Dry Cone Filters

Carbon Fiber Inlet Ducts

Silicon Coupler Internally Stepped

Laser Cut Stainless Steel Brackets

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.

THE EVENTURI DIFFERENCE

The 991 GT3 RS Eventuri system uses their Patented Carbon fiber Housings which provide an aerodynamically efficient airflow path from the filter to the engine. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect.

Eventuri’s intake has been independently tested by ES Motors who build high powered Porsches in the UK. Tests were done on the same day back to back using a chassis dyno. As can be seen, there is a measurable gain throughout the RPM range, not just at peak which is more important as the increased area under the graph demonstrates that the intake is making an impact beyond the headline figures. This gain even on a stock car is noticeable on the road with better throttle response and quicker acceleration. The first graph is the summary of results and the second is a screenshot of the dyno test to show the gain in the mid-range.

ABOUT EVENTURI

Eventuri was founded by a team of engineers and enthusiasts with a background in Aeronautics and tuning – all sharing a passion for cars and performance.  Eventuri Intakes are extensively developed using cutting edge design, testing and prototyping methods. With a focus on performance, each design undergoes CFD analysis and is then validated at the prototype stage through volumetric airflow, intake temperature and extensive dynamometer testing. We strive to publish all the development information to illustrate the depths we go to in bringing an intake from concept to reality. After many years of disappointment with the usual aftermarket intakes, Eventuri are proud to be raising the bar and creating intake systems which are setting a new standard and genuinely improve performance.
