No flame intended: I understand that is your real world experience and that is fine. But that's an awfully general statement to make about those brand of plugs. I'm making over 600 HP and I never melt down my Autolite 3922 plugs with the correct tune. I have however melted down NGK's with a lean tune. And I would never put an AC Delco plug in my car
