The NGK Laser Iridium spark plug blends high durability and long life using an iridium-tipped center electrode that is significantly harder than platinum. Engineered as an OE-equivalent replacement for performance-minded applications, many Laser Iridium plugs include a platinum pad on the ground electrode for even wear in distributorless systems. High-grade alumina ceramic and a copper core prevent overheating and promote dependable starts.
