EVENTURI EVE-GR86-CF-INT Air Intake System (Carbon, Gloss) for TOYOTA GR86 (ZN8) / SUBARU BRZ (ZD8) 2022-

The Eventuri intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. Use 100% pre-preg carbon fiber with no fibreglass which means can achieve a smooth internal surface to maintain smoother airflow.

Each intake system consists of:

• Carbon Fiber Patented Venturi Filter Housing with integrated MAF section
• Bespoke High Flow Dry Cone Filter
• Carbon Fiber Dual Feed Inlet Duct
• Laser Cut Front Air Scoops
• Custom Made Hardware
• Laser Cut Stainless Steel Brackets
• CNC Machined MAF Boss and Bracket Mounts

Filter housing assembly

The filter housing comprises of bespoke generation 2 filter, aluminium inlet cowl and the integrated MAF section. The carbon pod shrouds the reverse mounted filter and smoothly shapes the airflow down to the MAF section which then connects to the rear inlet tube. This changes the flow path from the OEM airbox where airflow enters the front of the airbox, changes direction by 90 degrees to travel through the panel filter and then changes direction again by 90 degrees to move through the MAF section. System is a lot more direct with airflow entering the front of the filter housing and and moving into the MAF section without any abrupt direction changes. The result is a smoother path from the filter to the turbo inlet tube and therefore the turbo is able to function with less drag. To ensure a reliable seal with the MAF sensor, use a CNC machined mount secured to the carbon housing.

Patented technology

Patented filter housing has a smooth reduction in cross sectional area as it shrouds the filter and tapers down to the tubing. This geometry invokes the Venturi effect where the airflow accelerates whilst maintaining laminar conditions. It can be thought of as a large velocity stack. Bespoke filters aid the airflow moving through the housings and allow for an even velocity profile as the airflow exits the housings.

Carbon duct

The duct feeds the filter housing with ambient airflow from the front bumper/grill section. Through testing several iterations found that a dual intake where cold air was taken from both openings in the slam panel area, functioned in the least restrictive manner. The region in the front bumper area is saturated with cold air from scoops and also from the natural design of the OEM cavity behind the bumper. The duct has an expanding rubber seal which mates to the filter housing to ensure heated engine bay air is kept away from the intake feed, but still allows for engine movement. It is mounted in 3 positions to ensure a secure fit.

Front scoops

The final components are 2 front scoops which sit behind the lower grill to direct ambient air upwards into the opening of the duct. This aids in keeping IATs low while the car is in motion. For owners with aftermarket oil coolers who cannot use the scoops, the IATs will still remain minimal due to the natural saturation of cold air behind the bumper.
