I read years ago that those plugs are real bears to get out.
What was suggested was to put a little spritz of penetrating lubricant in the recess in which the spark plug sits.
Do that a day or two before you want to take out the plugs, and drive it around for a bit to let the plugs heat up and cool down a few times.
It worked for at least one guy. I hope it works for you, too. Those plugs were hard enough to get out that dealership techs were breaking them and having to drill them out.
That’s no fun at all, and you don’t make any money when it takes so long to finish the job.
Good luck!

The dryer you keep the chamber threads the better. This way you achieve true torque after running the plugs in...28' lbs.

Weird how so many people assumed that Ema was a woman and offered typical "man advice". The poster asked about doing the spark plug repair if it was needed. There are probably many many men on this forum that aren't skilled enough to do that repair. There are recent posts about men getting stuck trying to get it done and coming to the forum for help.
That was the question and they got a bunch of advice about doing a tuneup and torquing plugs. Kind of funny.
