The NGK Laser Iridium spark plug combines long life with dependable OE‑level performance. A fine iridium center electrode and high‑grade alumina ceramic insulator provide consistent spark and heat control, while a copper core aids heat removal to prevent overheating. Many versions include a platinum pad on the ground electrode for even wear in distributorless systems. Suited as an OE or equivalent replacement for modern engines.
