The present invention provides a device 200 that is capable of increasing fuel economy and engine performance whilst reducing exhaust emissions. The device 200 includes a fixed orfice 224 in an air flow channel between ambient air and a coupling means 226. The size of the fixed orifice 224 is pre-selected for a given type and size of engine. The flow or volume of air provided by the fixed orifice 224 is directed into the plenum chamber or intake manifold of the engine, and preferably downstream of the engine's management system. |
