These Autolite copper core spark plugs feature a cold-formed steel shell with precision-rolled threads, a full copper core electrode to provide better performance, and a one-piece terminal post to add strength. They use a copper-glass seal that bonds the insulator and terminal post center electrode together, ensuring full voltage at the spark gap, and a 100 percent leakproof gas-tight seal.
