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 Eventuri 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, Eventuri have been able to allow the V8 engine to breathe with greater efficiency and therefore gain power. In addition to the new tube design, Eventuri also identified a further restriction in the air feed system. To overcome this Eventuri 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.
