BMW Gloss Black Carbon Cold Air Intake - Eventuri EVE-M2C-CF-INT

The F87 M2 Competition intake system is designed to allow the turbos to work more efficiently. By replacing the stock airbox system with Patented Venturi filter housings and smoothly curved tubes, the airflow to the turbos is more laminar thus they can spool with less drag. Since the M2 Competition does not have air openings behind the grills, Eventuri also added sealed ducts to ensure that the intake temperatures stay as low as possible. The combination of the Venturi housings, organically shaped tubes, and sealed ducts result in an optimized intake which sets a benchmark for this platform.

The M2 Competition Eventuri system uses Eventuri's Patented carbon fiber housings with their Gen 2 bespoke filters. This provides an aerodynamically efficient airflow path from the filter to the turbos. This system is not just another cone filter with a heat shield but a unique design that invokes the Venturi effect and maintains laminar flow conditions to reduce the drag on the turbo. You can read more about the housing design and how it works HERE.

The Eventuri M2 Competition intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. Here are the details for each component and the design ethos behind them:

Each intake system consists of:

• x2 carbon fiber venturi housings
• x2 high flow gen 2 flters
• x2 aluminium cowls for smooth airflow entry
• Left and right side carbon tubed with integrated MAF sensor mount
• x2 carbon fiber sealed intake ducts
• x2 carbon fiber front scoops
• Laser cut stainless steel brackets
• High-quality silicone couplers with BMW specification hose clamps

Carbopn fiber fousings



The filter housings comprise high-flow filters, aluminum cowls, V-band clamps, laser-cut brackets, and the Patented carbon pods themselves. The carbon pods shroud the reverse-mounted filters and smoothly shape the airflow down to the intake tubes. This geometry invokes the Venturi effect where the airflow accelerates whilst maintaining laminar conditions. It can be thought of as a large velocity stack - below is a diagram to show the comparison between our patented design and a regular intake system. Our bespoke filters aid the airflow moving through the housings and allow for an even velocity profile as the airflow exits the housings.

Carbon sealing ducts



The filter housings are positioned with the openings sealed against the carbon ducts. These ducts have been designed to fit over the stock cold air ducting channels and direct ambient air into the filters. These ducts seal the openings of the filter housings and prevent heated air from entering the filters.






Carbon intake tubes





The intake tubes are again crafted from 100% prepreg carbon fiber. Each tube has an integrated MAF sensor mount which is CNC machined from aluminium. The shorter left side tube smoothly transitions from the carbon housing down to the turbo inlet tube. The longer right-side intake tube has to clear the fan shroud and strut brace. To do so Eventuri employed the same principle as the stock tube in changing the cross section from a circle at the turbo inlet tube to an oval for clearance over the shroud, then back to a circle at the filter housing end. This ensures these transitions are gradual so as not to disrupt airflow. The same cross-sectional area was maintained in order to keep the velocity through the tube constant.

Carbon fiber scoops







The final components in this system are the front scoops - essential to direct ambient air to the ducts and then to the filters.

The scoops are designed for maximum efficiency in directing the incoming air to the stock duct openings. Many aftermarket scoops have a large flat area almost perpendicular to the oncoming air - not great for channeling it into the ducts as the airflow just "hits" this flat portion and creates turbulence.

The Eventuri Scoops have been designed to sit directly behind the front grills to capture as much air as possible and with a continuous curve to the duct opening to ensure this airflow is efficiently channeled. CAD images to illustrate the shape:



Having an effective cold air feed to the filters is an essential part of our design. Simply having some heat shields in place is not an effective means of preventing heated air from entering the filters unless the shields create an air-tight envelope around the filters. The scoops and ducts in our system combine to provide the filter openings with ambient air and maintain a low intake air temperature.

All the components come together in the engine bay to produce a genuine improvement in the driving experience and to provide an incredible visual display of form and function in complete harmony.
