BMW F90 M5 V2 Eventuri Intake System
Acceleration time : 60-130 mph reduced by 0.22 seconds
Maximum airflow per airbox at 28″ H2O: Standard 620 CFM, Eventuri 736 CFM
The F90 M5 Eventuri intake system is the result of extensive real-world testing and airflow simulations. The new V2 version has been improved with sealed filter housings, which ensure a more stable intake air temperature (IAT), even when the car is stationary. The new shrouds, which seal the housings, along with our scoop and shield combination, ensure unobstructed airflow and maintain low IAT values through cold air replacement. Our large front air intakes direct cold air directly to the intake area, protecting the engine from heat absorption. Furthermore, our gold heat-reflecting shields feature integrated air guides that direct airflow to the filters. We've also increased the intake duct surface area by more than 30% compared to the standard intake, which offers less restriction to the turbochargers and reduces wastegate cycles.
The Eventuri Difference
The Eventuri F90 M5 system utilizes our patented carbon fiber housings with custom-designed Generation 2 filters, which ensure aerodynamically efficient airflow from the filter to the turbochargers. This isn't a conventional cone filter with a heat shield, but a unique design that utilizes the Venturi effect and maintains laminar airflow to reduce drag on the turbocharger.
The Eventuri F90 M5 Intake consists of the following components:
- 2 x Carbon Fiber Venturi Housings with integrated tubes
- 2 x Custom High Flow Generation 2 Filters
- 2 x Carbon Fiber Filter Shrouds
- 2 x Aluminum Inlet Cowls
- 2 x Carbon Fiber Air Scoops
- 2 x Laser Cut Heat Shields, coated with gold heat-reflective material
- 2 x Laser Cut Air Ramps integrated into the Heat Shields
- High-quality silicone couplers and OEM-spec hose clamps
Intake Housing Assembly
The filter housings consist of our custom-made Generation 2 filters, aluminum intake cowls, carbon shrouds, the carbon fiber pods, and integrated tubes. The carbon fiber pods enclose the reverse-mounted filters and direct airflow to the turbo inlet tubes. This is a key design feature that eliminates the need for a convoluted rubber hose between the airbox and the turbo inlet tubes. The housings and integrated tubes move as a single unit with the engine via the strut braces, eliminating additional interfaces that would disrupt airflow. The result is smoother airflow from the filter to the turbos and less drag on the turbos.
Internal Volumes
Another key design feature is the internal volume of the tubes that pass through the strut braces. We increased the internal surface area at this transition by 31%, creating more available volume for the turbos to draw air and thus reducing restriction.
Patented Technology
Our patented filter housings have a smooth decrease in cross-section as they surround the filters and slope down to the tubes. This design utilizes the Venturi effect, where the airflow accelerates while maintaining laminar conditions. This can be thought of as a large velocity stack, which increases airflow efficiency and optimizes turbocharger performance.
Carbon Shrouds
These carbon fiber shrouds are a recent addition to this intake system. They seal off the openings for the filter housings from the engine compartment, while still allowing air to flow to the filters through the front scoops. The shrouds follow the design curves of the housings and extend to the inside of the wheel arches, where a rubber seal allows the intakes to flex as the engine moves.
Heat Shields and Air Ramps
The filter housings sit atop laser-cut heat shields, which are coated with a gold, heat-reflective layer to reduce radiant heat transfer. These shields create a sealed space for the filter openings, directing cool air from the scoops to the filters. Integrated air deflectors in the shields direct airflow from the scoops upwards toward the filters, displacing warm air from the engine compartment.
Front Scoops
The final carbon fiber components in this system are the front scoops, which are essential for efficiently directing ambient air toward the filters. The scoops are designed to guide airflow as effectively as possible toward the air intake openings, with a streamlined design that prevents turbulence.
With this intake system, the BMW F90 M5 will experience a massive performance boost due to the reduction in air resistance and the addition of an unmistakably grittier sound experience, taking the driving experience to the next level.
