BMW Gloss Black Carbon Cold Air Intake - Eventuri EVE-F1XM6-INT

The F12/F13/F06 M6 Eventuri intake system was developed through extensive dyno testing, maximum velocity tests, and flow optimization. Eventuri developed a complete system from front air scoops to filter housings and even inlet tubes to the turbochargers. The resulting system is very efficient and reduces the resistance to the turbos by giving a smooth path for the airflow to travel through.

This system uses a Patent Pending carbon fiber housing which provides an aerodynamically efficient airflow path from the filter to the MAF tube. This system is not just another cone filter with a heat shield but a unique design that invokes the Venturi effect. You can read more about the housing design and how it works HERE

This 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 double cone air filters
• x2 aluminium cowls for smooth airflow entry
• Left and right side carbon tubes with integrated MAF sensor mount
• x2 carbon fiber front scoops
• x2 carbon fiber front Scoop Extensions
• x2 laser cut aluminum shields with integrated flow deflectors
• High-quality silicone couplers with BMW specification hose clamps

Carbon Intake Housing Assemblies



The filter housings comprise the high-flow filters, aluminum cowls, and the carbon pods themselves. The carbon pods shroud the reverse-mounted filter and smoothly shape the airflow down to the intake tubes. This smooth reduction in cross-sectional area 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 patent pending design and a regular intake system. Further details can be read on the Technology page.

Carbon Fibre Intake Tubes

Our 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 tubes smoothly connect the filter housings to the turbo inlets and eliminate the stock corrugated flexi-tubes which have a much more disruptive flow path. We ensured that the carbon tubes maintained a true circular cross section - even at the MAF boss for the best possible flow characteristics.



Carbon Fibre Air Scoops





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

The scoops were 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. For the M6 variant in particular, we also added 2 carbon fiber scoop extensions to connect the scoops to the front grills. This gives the incoming airflow a continuous path through the scoops into the stock ducts.

Unlike most aftermarket "scoops" the Eventuri Scoops have been designed to extend from the stock duct openings all the way to the grills. In order to capture as much air as possible, the scoops are shaped to the same contours as the outsides of the grills and then smoothly channel ambient air through a continuous curve to the duct openings.

Shields / Flow Deflectors



The filter housings are positioned with the openings nestled inside the flow deflectors. These deflectors capture the cold air coming in from the front scoops and help displace hot air from around the filter openings. Here is a CAD image to illustrate the configuration of the filter housings, deflectors, and scoops. The path between the scoops and deflectors is taken up by the stock ducts.

To illustrate - here are the left and right-hand side intakes assembled as they would be in the engine bay with the tubes and ducts:
