ABSTRACT:
A rotationally interlocked heat shield and spark plug boot seal assembly with internal air flow cooling passages that also provide fluid drains to keep the boot seal dry. The shield doubles as a boot seal removal tool for service and grounds to the cylinder head instead of the spark plug giving good feel when engaging the spark plug clip. Corona and dielectric puncture is reduced by grounding the shield and coating the internal diameter of the shield with a suitable conductive layer of material.
