GM/Chevy spark plug boot removal tool

I made this tool for my 01 Yukon XL 1500 5.3L. This should work for any other engine that uses this type of head shield. The spark plugs boots have a heat shield on them and if those boots have been attached to the spark plugs for a few years they can be a pain to remove. This tool works on all the plugs even the ones with minimal space in the back.

Instructions: Slide the open end over the plug wire and expand it enough to slip over the heat shield until the lip settles into the groove. Then take a pair of pliers (I found needle nose vice grips work well for constant pressure so they don't slide off) and something to pry/leverage the boot off.

I plan to make a video of this sometime. I sold my Yukon so I don't have a demo vehicle :(. I plan to get another later on though.
