NGK Laser Iridium spark plugs combine long service life with strong ignitability for OE and high-demand applications. A fine iridium center electrode resists wear far beyond platinum, while NGK's high-grade alumina ceramic and copper core help manage heat and ensure reliable starting. Many Laser Iridium designs also feature a platinum pad on the ground electrode to promote even wear in distributorless ignition systems.
