The F87 M2 Competition intake system is designed to to allow the turbos to work more efficiently. By replacing the stock airbox system with Eventuri 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 our Venturi housings, organically shaped tubes and sealed ducts result in an optimised intake which sets a benchmark for this platform.
The Eventuri Difference
The M2 Competition Eventuri system uses their Patented Carbon Fibre Housings with our Gen 2 bespoke filters, which provide an aerodynamically efficient airflow path from the filter to the turbos. Not just another cone filter with a heat shield but a unique design which invokes the Venturi effect and maintains laminar flow conditions to reduce the drag on the turbo.
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:
- 2 x Patented Carbon Fiber Venturi housings
- 2 x Bespoke High Flow Generation 2 Filters
- 2 x Aluminium Cowls for smooth airflow entry
- Left Side Carbon Tube with integrated MAF sensor mount
- Right Side Carbon Tube with integrated MAF sensor mount
- 2 Carbon Fiber Intake Ducts
- Laser Cut Stainless Steel Brackets
- High quality Silicon couplers with BMW specification hose clamps
FILTER HOUSING ASSEMBLIES 
The filter housings comprise of the high flow filters, aluminium cowls, V-Band clamp, laser cut brackets and the Patented carbon pods themselves. The carbon pods shroud the reverse mounted filter 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. Eventuri's 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 
Eventuri's intake tubes are again crafted from 100% prepreg carbon fibre. 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 they 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. Eventuri ensured these transitions were gradual so as not to disrupt airflow, furthermore we maintained the same cross sectional area in order to keep the velocity through the tube constant.
All the components come together in the engine bay to produce a genuine improvement in the driving experience as well as providing an incredible visual display of form and function in complete harmony.
