Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hello I will help,
The tool is a flat piece of metal with a small hook on the end you can slip along the plug and catch the bottom of the boot to help pull it off the spark plug. (click here).
I prefer a wiper blade support rail I bend the tip to a hook.
Other ways to remove are get the straw of a can of silicone spray or WD-40 inside the boot and spray or the tip of a compressed air nozzle and blow.
If the boot is stuck plan on replacing all wires, one way or another you have to dig any remaining boot off the plug in order for the sprak plug wrench to fit.
Let me know how I can help
