Thanks for the tip.

As long as your socket is securely over the hex portion of the plug it won't break the plug. When the spark plug breaks, it's between the metal hex and ceramic body. However, if the plug is seized on to the head, I imagine, one could strip the thread off the head.
I myself, if concerned, might vacuum the plug hole as much as possible and blow out with compressed air, spray WD40, let it soak overnight and loosen. However, WD40 in the hole can lead to dirt flowing into the combustion chamber when the plug is removed.
