The NGK Laser Iridium spark plug combines a fine-wire iridium center electrode with OE-quality design for durable, consistent sparks and extended life. Iridium’s superior melting point and hardness resist wear, while the high-grade alumina ceramic insulator and 98% pure copper core help prevent overheating. A platinum pad on the ground electrode is common for even wear in distributorless ignition systems, supporting reliable starts.
