NGK Laser Iridium spark plugs in a box of four deliver OE-style durability and a stable spark for fine-wire applications. The iridium-tipped center electrode is extremely hard for long life, while a high-grade alumina ceramic insulator and a 98% pure copper core aid heat removal. Many designs also use a platinum pad on the ground electrode for even wear. Triple seals and corrosion-resistant plating protect against leakage and seizing.
