Abstract: A multi-part module including a flame cone and a connector adapted to be interposed between the normal spark plug port in an internal combustion engine block and a spark plug suitable for use with the engine in question. In the method, a quantity of fuel/air mixture is captured in a chamber which also houses the electrode of a spark plug. Upon generation of a spark from the spark plug, this quantity of fuel/air mixture ignites, generating a flame which propagates through one or more channels in a flame cone interposed between the spark plug and the cylinder of the engine and exits into the cylinder through multiple directionally oriented ports, whereupon the flame fronts rapidly ignite substantially all the fuel/air mixture held within the cylinder.
