An air injector plate is positioned between the carburetor and the intake manifold. The air injection plate includes capillary air orifices feeding constantly controlled quantities of air into the air-fuel mixture passing from the carburetor to the intake manifold during operation of the engine. A flexible tubing having an air filter removably associated therewith is connected to the air injector plate.
