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.
