Eventuri BMW E90 E92 E93 (M3) Carbon Fibre Air Intake System

The Eventuri E9X M3 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:

  • Carbon Fibre Intake Tube
  • High Flow Urethane Cone Filter
  • Carbon Fibre inlet Scoop
  • CNC Machined breather adapter
  • Laser Cut Stainless Steel Debris Guard
  • Silicon Coupler and OEM specification clamps

The intake tube was designed to improve the airflow path compared to the stock tube – from the filter to the manifold. It is a 1-piece design which has no internal interfaces and therefore provides a much smoother path for the airflow to negotiate. Furthermore the geometrical transition is from a circular opening for the filter to the oval exit for the manifold. This is a much more efficient change in shape when compared with the stock tube which has to transition from a rectangular opening for the filter to the oval exit for the manifold.

In order to appreciate the improvement in the design we must take a closer look at the stock system:

As can be seen – the stock intake tube has 2 concertina sections which are used to allow the tube some flexibility for engine movement. These sections introduce multiple internal interfaces to the oncoming airflow which results in turbulence and therefore a less efficient path for performance. The Eventuri tube on the other hand has zero internal interfaces and so airflow is allowed to stay laminar which allows the engine to breathe more efficiently.

The BMW E9X M3 Eventuri intake system is the result of extensive research and optimisation which improves possibly one of the best designed stock intake systems we have seen. The E9X stock airbox system is a brilliantly designed intake with an excellent flow path and feed system for ambient air. However on closer inspection, there are restrictions in the inlet tube connecting the airbox to the inlet manifold. By redesigning the tube yet maintaining the airbox, we have been able to allow the V8 engine to breathe with greater efficiency and therefore gain power. In addition to the new tube design, we also identified a further restriction in the air feed system. To overcome this we designed a scoop to allow an increase in airflow through the airbox. This reduces inlet temperature values further and adds to the performance gain of the system.
