Good advice. I only use copper plugs, none of those fancy platinum or iridium types which foul out easy if the coating on the tip comes off. Plus copper is a better conductor anyway. Just have to change them out every 10,000 miles on high performance motors. I will definitely do the plugs now. Not sure why I didn't pull them yet and inspect. I guess moving last year and losing my shop has really thrown off my routine!
