Do these plugs come with a copper crush ring, or anything? I don't remember my last ones coming with anything. I've installed other plugs on other cars since last install on the ls1, and it seems like all the other plugs came with some kind of copper sealing washer/ring????

I've got the antisieze, can I just put these babies in?
