Thanks guys for the replies.
It's not really a big deal one way or another ont he money I just want to get a plug that works well with the car and lasts reasonalby well. My daughter will be away at college and I won't have the access to it for the maintenance.
What kind of miles can I expect as a rule of thumb from the coppers before they should be changed? I know the iridiums are higher mile plugs...
If I go copper it looks like Autolite 606, if I go iridium it looks like XP606 or ACdelco 41101.
