Those came out of my truck at about 27K miles.

What Matt sez. About a week prior to me replacing them, I pulled #1 and #6 just to see what they looked like and how they'd come out. At that time, I didn't really plan on replacing all of them, so I put a little dab of dielectric grease on those two and slammed them back in. That black stuff is the residue of the grease on those plugs.
Just curious, how soon should I replace the plugs on my truck? I do a lot of stop and go driving. (I'm an A/C contractor) I waited until 100k on my V-10, and they looked fine. Also has Ford resolved the problem with plugs blowing out?
