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. Each intake system consists of. High Flow Urethane Cone Filter. 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. An important challenge to overcome was the requirement of movement with the engine. Instead of using silicon couplers with flexible sections (which would introduce similar interfaces as the stock tube), we designed the tube itself to be able to move with the engine. The tube has a compressible neoprene band around the section which interfaces with the stock airbox.

This section seals the tube to the airbox yet allows movement in and out of the airbox as the engine moves. By allowing the tube itself to move - we have been able to create a flow path which is as smooth as possible.
