I am in Mansfield and the plugs have already been replaced and the replacements are 4 years old and have 90k on them. Is your work performed at a shop or your house?
We're are you located? I can do 3v spark plugs. They will sometimes break no matter how you do it. Especially if it's got high miles on original plugs. But with the 3v spark plug extracting tool it's not a huge deal if they break just a little more work. I'm in Richardson. $100 to replace all 8. $15 per plug to be extracted. Usually doing them hot and removing with impact gun slowly breaks them loose. But with newer revised plugs next time it's done none should break anymore. Especially if you do them every 60k.
