The NGK Laser Iridium spark plug (box of 4) pairs long service life with precise ignitability using a fine-wire iridium center electrode that lasts far longer than standard materials. High-grade alumina ceramic and a copper core help prevent overheating and provide reliable starts. Many designs include a platinum pad on the ground electrode for even wear in distributorless systems, making these plugs suited to high-tech OE applications.
