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.
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:
