When removing the spark plugs from a warm motor can burn ya....
Here is a trick I learned while on a Nascar team 30 yrs ago.
Use a 3/8 piece of rubber tubing after breaking loose the plug
and slip it over the plug-- remember "righty tighty lefty loosey"
turn the rubber tubing till the plug comes off.. Waaaa Laaaa
You can use the rubber tubing in the reverse as well. Especilly in tight places!!
