EVENTURI Intake for BMW M2 CS
Fitment for BMW M2 CS F87
Performance Gain: 10-15 hp, 10-15 ft-lb
The F87 M2 CS Eventuri carbon 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 optimized intake which sets a benchmark for this platform.
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.
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.
Couple the dAHLer engine performance tuning increase with a more audible and sonorous induction sound of your BMW M2 CS and the overall driving experience is much more involving and more fun.

Why Eventuri Intake?
EVENTURI INTAKE SYSTEM
The Eventuri carbon intake system for the BMW M2 CS is a new type of intake design, which has been granted a patent. Eventuri uses a cone filter – but here it is inverted and decoupled from the inlet tube. By removing the direct connection between the filter and the inlet tube, the filter is no longer dictating the shape of the airflow. This is now being done by the carbon housing, which is designed to smoothly guide the air into the inlet tube without a sudden change in geometry.
This means that Eventuri keeps laminar conditions throughout the intake, which is a lot more efficient. Furthermore, the funnel-shaped housing invokes the Venturi effect where the smooth reduction in cross-sectional area along the length of the housing causes the airflow to increase in velocity. Essentially the entire housing acts as a large velocity stack. On the road this translates to more power with a smoother delivery as well as sharper throttle response since the airflow is not inhibited by abrupt geometry changes.
RESULTING IMPROVEMENTS FOR BMW M2 CS
Dyno testing the Eventuri intakes back-to-back with the original filter vs the upgraded filter, Eventuri has found an additional power and torque increase for tuning the BMW M2 CS, like an engine performance tuning module. This validates our theoretical modelling and proves that the upgraded filters really have a significant impact on the airflow through the intake. The power gains over and above the original filters vary between vehicles, but here are some of the results Eventuri has measured so far.
