Ha, not what you thought.
With all the spark plug talk here lately I thought I'd let everyone know the Champion 4412 copper truck plugs ARE still available. A lot of old school Jeepers swear they're the best. O'Reilly's and others will tell you they're discontinued, but I found some at Carquest awhile back and they said they always have them in stock. HUB also has them, I don't know if they're a nationwide chain. The guy at Carquest said they call them truck plugs because they're for heavy duty applications. I would only recommend them for pre 2000 TJ's, otherwise you'll have to change them at 15K, not 30K. Are they better than platinums? I don't know, but my Jeep runs great. And platinums will last 3 times as long. But how cool is a black and gold spark plug
