A torch jet spark plug (10) for use in a spark ignition system of an internal combustion engine. The spark plug (10) of this invention provides for ignition of an air/fuel mixture within a combustion prechamber (12) within the plug (10), which creates a jet of burning gases that are propelled through an orifice (32) into the engine main combustion chamber to increase the burning rate of the air/fuel mixture within the combustion chamber. The orifice (32) is oriented in the plug (10) so that its axis is not parallel with the longitudinal axis of the plug (10), enabling the jet of burning gases to be selectively directed to any desired region within the combustion chamber, such as a region within the chamber that would not otherwise burn well compared to other regions of the chamber.
