Its specially engineered high nickel alloy center and ground electrode provides extended life
Its multi-rib ceramic insulator reduces danger of flash-over while its copper-glass seal bonds the center electrode and terminal post, providing a gas-tight internal seal
Its cold-formed steel shell precision rolled threads provide for greater durability and reduced wear
