The NGK Laser Iridium spark plug uses an iridium fine-wire center electrode with premium alumina ceramic insulation and a copper core to provide long life and stable spark performance. Many models include a platinum pad on the ground electrode for uniform wear in distributorless systems. The design supports reliable starts, strong idle stability and durability under higher engine temperatures for drivers seeking upgraded ignition components.
