Heavy duty yttrium-enhanced center electrode with copper core provides superior reliability and durability for up to 50% longer performance life than standard nickel plugs. Nickel-plated rolled threads provide anti-seize and corrosion protection. Metal glass fused resistor gives maximum interference suppression. Angular, 5-rib insulator design prevents flashover.
