I thought these were good for 100K miles? But with the recent news of possibly damaging them... Changing them out may be a good thing after all.

Did Ford forget to put anti-siez on em or what? why are they breaking off in the heads? anyone know?

Pull them and see if they look bad. If they look good, then put some anti-seize on them and reuse them. I think you would be better off to get them out now. I have 17000 miles and two of them were already a pain to get out. Luckily none broke. The plugs looked good so I'm reusing them but putting anti-seize on them so I won't have the worry down the road when they need to be replaced.

+1 Sounds like good advice plus, if you don't already know which heads you have, you'll find that out too.[&:]
