NGK Laser Iridium spark plug set (box of 4) offers high ignitability and extended life for OE-style engines. A fine iridium-tipped center electrode provides superior durability versus platinum while NGK’s high-grade alumina ceramic and 98% copper core promote heat management and reliable starting. Raised platinum pads or fine-wire tips on the ground electrode ensure even wear and improved spark behavior in distributorless ignition systems.
