WZAJ's iridium series are the latest addition to their plug line-up. Ultra fine wire center electrode and tapered ground electrode increase ignitability and reduce spark quenching. Laser welded iridium tipped center electrode and iridium-platinum alloy tipped ground electrode promote durability and long life. Copper core helps prevent pre-ignition and fouling. Nickel-plated shell and rolled threads provide anti-seize and corrosion protection. Ribbed insulator prevents flashover.
