The NGK Laser Iridium spark plug delivers long service life and stable ignition through a fine-wire iridium center electrode and robust ceramic insulation. Built to OE standards, its iridium tip is harder and more heat resistant than platinum, while a copper core helps manage heat for reliable starting. The combination of high melting-point materials and precise electrode design supports consistent ignition and durability in modern high-temperature engines.
