Heavy duty yttrium-enhanced center electrode with copper core provides superior reliability and durability. Tapered cut nickel chromium ground electrode assists in cold weather starts and provides increased ignitability. 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.
