The NGK Laser Iridium spark plug balances longevity and high ignitability for OE-style replacement use. A fine iridium center electrode resists wear and maintains a stable spark, while premium alumina ceramic and a copper core help control heat for reliable starts. Many Laser Iridium plugs include a platinum pad on the ground electrode to ensure even wear in distributorless ignition systems.
