Eventuri proudly presents the C8 ZR1 Intake System, a comprehensive engineering achievement delivering ground-breaking performance gains rarely seen from an intake upgrade alone.
Building on proven success with the C8 Stingray and Z06 platforms, Eventuri elevated the ZR1 system even further by incorporating high-flow turbo inlet tubes, each designed to be 30% larger in volume compared to the OEM tubes. This allows the turbochargers to achieve peak boost targets with greater efficiency. Unlike the factory configuration, the intake system is not constrained by the OEM trunk panel. This freedom allowed Eventuri to engineer a significantly larger intake architecture while also transforming the engine bay presentation. A clear polycarbonate trunk panel reveals the full carbon fibre intake system when opened—turning the engine compartment into a visual centrepiece.
The OEM ZR1 airbox, derived from the LT6 Z06 design, retains several inherent limitations. Its restricted shape and limited internal volume are dictated by the packaging constraints behind the factory trunk panel. When paired with the higher-output LT7 engine, these restrictions become even more pronounced. Eventuri's solution eliminates these bottlenecks through an organically shaped, high-volume intake system combined with a patented Venturi housing design. This configuration optimizes airflow efficiency and reduces restriction throughout the intake path.
The result is a substantial increase in power and torque across the entire RPM range, highlighted by a transformative improvement in mid-range performance—delivering the responsiveness and acceleration the C8 ZR1 platform truly deserves.
The Eventuri C8 ZR1 Corvette intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. 100% pre-preg carbon fiber is used with no fibreglass, which means a smooth internal surface is achieved to maintain smoother airflow. Here are the details for each component and the design ethos behind them:
Each intake system consists of:
- Carbon Fiber Double Venturi Filter Housing
- Bespoke High Flow Dry Cone Filters
- Carbon Fiber Inlet Ducts
- Carbon Fiber Turbo Tubes
- Clear Polycarbonate Trunk Panel
- Silicon Couplers
- Laser Cut Stainless Steel Brackets and Heat Shields
- Custom Inlet Flanges
- Custom Flexible Hoses
PATENTED FILTER HOUSING
The ZR1 Filter Housing features two patented Venturi pods, designed to merge into a large-volume intake chamber while integrating dual MAF tubes that precisely direct airflow to each turbocharger.
This system is the next evolution of the C8 Z06 housing, developed through months of intensive prototyping, testing, and data-driven refinement.
Inside the carbon fibre housing are two bespoke high-flow filters paired with aluminium cowls that help guide airflow directly onto the filtration surfaces. The housing surrounds the reverse-mounted filters and smoothly transitions airflow toward the MAF tubes.
As the cross-sectional area gradually reduces, the design creates a Venturi effect, accelerating airflow while maintaining laminar flow conditions—much like a large velocity stack. The result is highly efficient airflow delivery and improved turbocharger response.
BESPOKE CONE FILTER
The filter chosen for the ZR1 system allows for a balance between filtration area and overall filter housing volume. Initial prototypes used a larger filter, but these extended too far into the housing and disrupted the flow towards each MAF tube section. By using a shorter cone, the shape of the housing was optimised for better flow towards the MAF tubes while maintaining more than sufficient filtration area for the CFM demands. The filter medium is ISO tested to ensure that filtration is in line with OEM standards and is also dry. The filter is constructed with Eventuri's signature flow cones to aid in the Venturi housing principle.
CARBON TURBO TUBES
During performance testing, it became clear that the OEM turbo tubes were restricting the potential of the LT7 engine. By carefully analysing the available space, Eventuri redesigned them to increase the internal volume of each tube by 30%.
This significant gain in volume reduces airflow restriction, allowing the turbochargers to operate more efficiently and reach peak boost earlier in the RPM range.
By superimposing the OEM turbo tube CAD data against the Eventuri design, the difference in size and geometry becomes immediately apparent. Not only do the Eventuri tubes offer increased volume, but they also feature a more progressive curvature, carefully engineered to maintain smooth, uninterrupted airflow through to the turbos.
CARBON DUCTS
The ducts channel ambient air from the side vents to the filter housing. To ensure a good seal against engine bay heat, they are secured to the filter housing at 3 points and use a neoprene gasket for an airtight seal. The ducts were designed to have the maximum internal volume possible within the given geometry of the engine bay, ensuring that the filter housing is able to draw with minimum restriction.
CLEAR TRUNK PANEL
Designing an intake with large volume and smooth airflow to the engine was not possible within the limited space—in part due to the stock trunk panel—so Eventuri redesigned it to accommodate the intake. In doing so, the opportunity was taken to showcase the carbon fibre by making the panel from clear polycarbonate. This allows for a window to see the intake when the trunk is opened—an industry first for this platform.
The new panel allows the OEM roof from the coupe to be stored in the boot as intended.
BRACKET WORK
A framework has been designed to allow the OEM wiring looms to be secured in place and kept out of view. The bracket work is laser cut from stainless steel and aluminium.
INLET FLANGES
Custom inlet flanges and flexible hoses connect the intake to the stock cold air feeds on each side, ensuring that engine bay heat is kept out of the intake system. Bespoke flexible hoses designed specifically for the C8 platform allow the intake to move with the engine while maintaining a seal for the cold air feeds.
