Whatever came in it originally (AC Delco) or NGK equivalent. No need for the fancy BS gimmick plugs. I find them to be the cheapest on Amazon.

Check rock auto, when I brought my acdelco plugs a few months ago they had a rebate going on. I think I got back like $24, turned out to be the cheapest plug change I've ever done.
