Re: What spark plugs do you use?
AC Delco when I can, Autolite when I can't. Both great plugs. Copper always, swap em out every 20,000 to 30,000.
Oh - and I work at an autoparts store. Sounds like someone did a damaged return/swap, and another person put them back with the new ones, instead of junking them. It sounds like you got some used ones (how they made it past the return is beyond me) but return em and tell them you opened them up and they looked like that. They might give you some guff, but hold to your guns, insist you're telling the truth and if all else fails, demand to speak to the manager. No one puts up that much of a fight that is lying. They usually turn around.
Good luck!
