The C8 Corvette Eventuri intake sets a new benchmark on this platform for the highest performing intake and the largest internal volume available. With the intake size and shape restricted by the OEM trunk panel, we redesigned it to allow for a larger intake. In doing so we also made it from clear Polycarbonate to allow the carbon intake to be on display when the trunk is open. Utilizing 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 flow capacity has also been increased allowing higher powered builds to maximize on performance gains. Intake air temperatures have been minimized by ensuring a sealed system, taking advantage of the OEM air feeds as well as using carbon fiber which has a low thermal conductivity coefficient across the wall thickness. The resulting system provides industry leading performance gains and a noticeable improvement in throttle response.
The Eventuri Difference
The C8 Corvette Eventuri system uses our 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. You can read more about the housing design and how it works HERE

Dyno Testing
Our C8 Intake has been independently tested by Corvette specialists, Paragon Performance in Iowa and also by tuning specialists MSL Performance in the UK. The tests were carried out on completely stock cars with the stock airbox and Eventuri intake tested back to back on the same day. Paragon Performance conducted the tests in their closed cell environment while data logging the temperatures and fuel trim values. A fully stock C8 was tested with engine temperatures at a stabilized value and then the car was left on the dyno while the intake was installed. After installation the car was allowed to reach the same temperatures and then the performance data was measured. This ensured that the tests were conducted in an unbiased way with variables equalized across the stock airbox and the Eventuri intake.
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.
CFD Analysis
A CFD flow analysis was conducted on the intake to optimise the shape for smooth flow and therefore reduced drag. The simulation below shows a sweeping cut plot of velocities through the intake. The streamlines demonstrate how the intake takes turbulent flow upstream of the filters and shapes the flow to be smooth and linear as it collects and moves through the MAF tube section to the throttle body. The velocity increases as it moves through the MAF tube yet remains laminar and uniform throughout the tube to the engine.
