This uniquely designed tool easily removes "ripped" and "stuck on" spark plug boots where there is no access to grab the boot for removal. The tool slides into the confined space of the spark plug hole and with hand pressure, separates the stuck on boot from the porcelain part of the plug. This tool then slides out with the damaged boot leaving the spark plug exposed and easily removed. Made from quality heat treated steel, this tool comes in a High Tech black finish. Made in the U.S.A.
