thats interesting i've never done ANY with less than 90k miles on them, and i've never done them on a hot or even warm engine, i refuse to but if i have the chance while its warm i'll break them all loose, just that first initial crack, then fill the plug tubes with freeze off (napa carries it), let it sit for atleast 1hour then go to town on them working them out a little back in a hair, out, back in, like a tap.

i've done atleast 200 (plugs not vehicles) and still have yet to have one break using this method.

and i'll add that a coworker of mine has atleast 2 break off in the head on every truck he does no matter what, maybe i'm just that lucky.
