I've got 4 of 8 plugs out no problem. 3 of the other ones are broken in such a way the extractor kit should be able to fix (it's on order) with porcelain stuck in the snapped off electrode shield.

The last is broken at the jamb nut hex. Am I correct in assuming the extractor kit shouldn't be used to try to get this one out?

 

For this - it sounds like I'll need an Easy Out. Anyone confirm it's the #5 Easy Out I keep reading about? (Will move this into the Explorer forum.)

It's a 2006 Explorer.

 

All plugs replaced successfully. It was a #6 extractor that did the trick for the last one. (#5 too small).
