The F87 M2 Competition intake system is designed to to allow the turbos to work more efficiently. By replacing the stock airbox system with our 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, we 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 our 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. You can read more about the housing design and how it works HERE.
Below is a dyno graph showing the comparison between the Eventuri and the stock airbox on a M2 Competition. The car had no other modifications. As you can see, power and torque are increased through a large portion of the rpm range. This translates on the road to increased part throttle and full throttle response with the car pulling much more eagerly to the redline. The testing was done on the same day back-to-back and temperatures were monitored to ensure consistency. The hood was closed for all runs.
WHAT'S IN THE BOX:
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. Our bespoke filters aid the airflow moving through the housings and allow for an even velocity profile as the airflow exits the housings. Further details can be read in the Technology and Filters pages.
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
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.
Our 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 we 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. We 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.

DESCRIPTION
The BMW G20 B48 Eventuri intake has been developed to provide the turbo with a less restrictive flow path whilst maintaining low inlet temperatures. Heat and Volume are the main considerations when designing an intake for turbocharged engines. In the G20, the intake system is located next to the exhaust manifold which rapidly heat soaks the engine bay. High temperatures are detrimental for engine performance as the turbo would have to build boost with heated, less dense air and so the only way to ensure IAT’s are kept to a minimum is for a fully sealed intake. This, however, results in a restriction with only one stock air feed to draw air in from. During development, we noticed an additional opening into the wheel arch area and took advantage of this by adding a secondary feed to our airbox. Furthermore, our sealed airbox also has a heat shield with gold reflective to minimise the radiative heat transfer from the exhaust manifold. In order to maximise volume, we made the airbox as large as possible with a recess for potential strut braces. The stock convoluted intake tube is replaced with a smooth carbon tube which is also larger in internal volume with a starting internal diameter of 111mm (4.4″) smoothly tapering down to match the turbo inlet. The tube provides a smooth path from the filter to the turbo inlet. Finally, we use a custom-made high-flow dry filter which is ISO tested for filtration performance and has a larger filtration area than the stock filter.
TECH SPECS
The Eventuri G20 B48 intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. We use 100% pre-preg carbon fiber with no fiberglass which means we can achieve a smooth internal surface to maintain smoother airflow.

Dual Feed Carbon Fiber Airbox
Crafted from Prepreg Carbon Fiber, the airbox serves 2 objectives - to seal the filter against engine bay heat and to provide a dual cold air feed. Since the airbox is positioned next to the exhaust manifold it is crucial for the filter to be fully sealed so we designed the airbox to encapsulate the filter and at the same time provide a large internal volume. To seal the intake tube we have designed a laser-cut plate with a rubber sealing strip that secures to the airbox. The intake tube passes through the plate and the rubber seal ensures heated air does not enter the airbox. To further minimise heat soak, there is an additional heat shield with a gold reflective layer on the exhaust manifold side which effectively combats the radiant heat transfer.
Having a fully sealed airbox result in the problem of having a restriction for the cold air feed. The stock airbox draws air from a single duct which extends to the front bumper area. During development, we identified another area to draw cold air from which was a gap between the wheel arch and the chassis on which the airbox sits. To utilise this feed we extended a scoop at the back of our design which protrudes into the wheel arch and can even be seen after installation behind the front wheel. This second feed allows the turbo to draw from a larger area therefore reducing the restriction.
Carbon Inlet Tube
The G20 B48 OEM airbox system was updated in cars built after November 2018 where the airflow sensor was replaced with a temperature sensor in the inlet tube. Prior to this date, all airbox systems had an airflow sensor and for this reason, we offer 2 variations. The V1 intake which has an inlet tube to take the MAF (airflow) sensor and the V2 intake for cars built after November 2018 which uses a temperature sensor. The difference in the tubes can be seen below.
The stock inlet tube has a flexible and convoluted section to provide the movement with the engine. This however also adds the possibility of turbulence in the flow path as there are multiple faces that can cause eddies. We replace this with our carbon tube which is smooth and also has a larger internal volume. Unlike most aftermarket intakes we maximised the size of our intake tube, the OEM inlet tube has an internal diameter of 80.8mm or 3.2” at the filter end. Our tube for cars built after November 2018 has an internal diameter of 109mm or 4.3”. This equates to a massive 82% increase in cross-sectional area overstock. The tube smoothly tapers down to the stock turbo inlet to ensure airflow remains as laminar as possible. The tube also has CNC machined fitting for the temperature sensor and the breather adapter.
