Eventuri Carbon Intake System for C8 Chevrolet Corvette Stingray Convertible

The C8 Corvette Eventuri intake is revolutionizing performance with an innovative design that boasts the largest internal volume and highest-performing intake available for this platform*. By creatively redesigning the OEM trunk panel, the intake’s size and shape have been expanded. The newly designed panel, made from clear Polycarbonate, puts the striking carbon intake on display whenever the trunk is opened.

Utilizing Eventuri’s patented Venturi Housing concept, the intake offers an aerodynamically superior path for airflow. The air negotiates through the filters with fewer obstructions, thus reducing the system’s drag. By increasing the intake’s overall volume, flow capacity is enhanced, enabling higher powered builds to fully capitalize on performance gains. The intake maintains minimized air temperatures by featuring a sealed system that leverages OEM air feeds and utilizes carbon fiber, known for its low thermal conductivity coefficient across the wall thickness. The result? A system that delivers industry-leading performance improvements and a discernible enhancement in throttle response.

The Eventuri Difference

  • The C8 Corvette Eventuri system transcends traditional designs by employing patented Carbon fiber Housings. These provide an airflow path from the filter to the engine that is not only aerodynamically efficient but also leverages the Venturi effect, a phenomenon far beyond the capabilities of ordinary cone filters with heat shields. Comprising several expertly engineered components, each tailored for a specific function and fabricated to exacting standards, the Eventuri C8 Corvette intake system epitomizes quality and performance. It is crafted using 100% pre-preg carbon fiber, devoid of any fiberglass. This ensures a smooth internal surface, promoting a more seamless airflow.

Patented Filter Housing

  • The C8 Filter Housing is designed with two patented Venturi pods that merge into a single outlet. It includes two bespoke high-flow filters, aluminum cowls, laser-cut brackets, and the carbon pod itself. The carbon pod encases the reverse-mounted filters, smoothly shaping the airflow down to the throttle body. This gradual reduction in cross-sectional area initiates the Venturi effect, where the airflow accelerates while maintaining laminar conditions. The design can be likened to a large velocity stack, with more details available on the Technology page.

Bespoke Cone Filter

  • To maximize the flow rate, a filter element was crafted to use as much space in the engine bay as possible. This new filter, with an outside diameter of 192mm or 7.6″, has the ability to flow up to 900 CFM at 28″ H2O when tested with a 4″ opening housing. The dry filter is ISO-tested to comply with OEM standards and is constructed with signature flow cones to enhance the Venturi housing principle.

Carbon Ducts

  • These ducts are created to channel ambient air from side vents to the filter housing. Designed to ensure a tight seal against engine bay heat, they are secured at three points with a neoprene gasket. They are specifically shaped for maximum internal volume within the engine bay’s geometry, allowing the filter housing to draw with minimal restriction.

Clear Trunk Panel

  • The limitation of space for a large volume intake led to the redesign of the stock trunk panel. Created from clear polycarbonate, it serves as a window to exhibit the carbon fiber intake when the trunk is opened—an industry-first on this platform.

Bracket Work

  • A framework was developed to keep the OEM wiring looms hidden and orderly. This bracket work is meticulously laser-cut from Stainless Steel and Aluminum.

Inlet Flanges

  • Custom inlet flanges and flexible hoses are utilized to connect the intake to the stock cold air feeds on both sides. This design ensures that engine bay heat is effectively isolated from the intake system.

Silicon Coupler

  • A silicon coupler replaces the stock coupler to the throttle body. It is specifically designed to match the OEM throttle body and features internal steps that cover the wall thickness of both the throttle body and carbon intake, guaranteeing a seamless passage into the plenum.

Dyno Testing

  • The C8 Intake by the company has been examined independently by Corvette specialists Paragon Performance in Iowa, as well as tuning specialists MSL Performance in the UK. These evaluations were performed on entirely stock cars, comparing the stock airbox and Eventuri intake on the same day. Paragon Performance executed the tests within their closed-cell environment, logging temperatures and fuel trim values. A fully stock C8 was assessed with engine temperatures at a stable value, and then the car was kept on the dyno while the intake was fitted. After installation, the car was allowed to reach the same temperatures, and then the performance data was measured. This process ensured that the tests were conducted in an unbiased manner with variables equalized between the stock airbox and the Eventuri intake.
  • The results reveal a measurable gain across the RPM range, not merely at the peak, which is significant as the increased area under the graph signifies that the intake is having an effect beyond the headline numbers. This improvement, even on a stock car, is perceptible on the road, resulting in enhanced throttle response and more rapid acceleration.
  • Performance Gain – 15-18whp / 15-16ft-lb

CFD Analysis

  • A computational fluid dynamics (CFD) flow analysis was performed on the intake, aiming to fine-tune its shape to ensure a smooth flow and consequently minimize drag. The simulation displayed in the diagram below depicts a sweeping cut plot of velocities traversing the intake. This visualization illustrates the way in which the intake manages turbulent flow upstream of the filters, reshaping it into a smooth and linear pattern as it gathers and advances through the MAF (mass airflow) tube section toward the throttle body. Despite the increase in velocity as the flow navigates through the MAF tube, it remains laminar and uniform, maintaining a consistent flow pattern all the way to the engine.

About Eventuri

Eventuri emerged from the collective vision of a group of engineers and auto enthusiasts with backgrounds in Aeronautics and tuning, unified by their passion for cars and performance. Disappointed with the underwhelming gains provided by various intake systems over the years and the mismatch between claims and reality, they were motivated to innovate and set new standards in intake design and technology. Their mission: to engineer systems that deliver tangible performance improvements and to share legitimate performance figures.

Each Eventuri system undergoes extensive development using advanced design, testing, and prototyping methods. Prioritizing performance, every design is subjected to Computational Fluid Dynamics (CFD) analysis and then validated at the prototype stage through volumetric airflow, intake temperature, and comprehensive dynamometer testing. They are committed to sharing all development information, demonstrating the depths they delve into when bringing an intake from concept to reality. Only the highest quality materials are chosen for each component, including fasteners and fixings, to ensure the unmatched quality of the final product.

After years of frustration with standard aftermarket intakes, Eventuri takes pride in setting a new benchmark and creating intake systems that genuinely enhance your vehicle’s performance.

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.
We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
