Abstract: A flame and explosion preventive safety shield for detachable securement to the head block of an internal combustion engine in surrounding and encasing relation to each spark plug to provide a structural flame barrier between the spark plug and its high tension lead and the ambient atmosphere surrounding the engine. The safety shield incorporates a spark coil and a secondary lead for supplying high voltage current to the spark plug and one or more fine mesh wire screens arranged to form a heat sink-type flame barrier around the spark plug and the high voltage secondary lead of the spark coil to thereby isolate the spark plug and its high voltage lead from a potentially combustible atmosphere surrounding the engine.
