GM spark plug boot removal tool

thingiverse

I created this tool for my 01 Yukon XL 1500. The spark plug boots have a heat shield attached to them, and if those boots have been in place for several years, they can be challenging to remove. This tool works on all plugs, even the ones with minimal space at the back. I printed it in PLA without any issues. Instructions: Once printed out, 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 use a pair of pliers (needle nose vice grips work well for constant pressure so they don't slide off) and something to pry or leverage the boot off. I plan to make a video of this sometime. I sold my Yukon, so I no longer have a demo vehicle :(. I plan to get another one later on though. I will also be adding this to Shapeways, so anyone without a printer can still get one. https://www.shapeways.com/product/WED3B5S4N/gm-chevy-spark-plug-boot-removal-tool
