ABSTRACT:
A spark plug quick release system is provided including a spark plug with an annular detent formed therein. An adapter is provided with a hollow cylindrical configuration having a lower end with a plurality of threaded grooves formed in an outer surface thereof for screwably coupling with a spark plug threaded mount. Next provided is a quick release assembly including a sliding tube slidably situated about an outer surface of the adapter. By this structure, the sliding tube has a lowered orientation and a raised orientation wherein ball bearings protrude from the corresponding circular aperture of the adapter. As such, upon the lowering of the quick release assembly and the insertion of the spark plug within the adapter, the quick release assembly may be released such that the ball bearings engage the annular detent of the spark plug.
