NGK Laser Iridium High Ignitability spark plug pairs advanced tip technology with long life for demanding OE applications. A fine iridium center electrode and raised platinum pad or fine wire tip on the ground electrode promote even wear and improved spark performance in distributorless ignition systems. High-grade alumina ceramic and a copper core control heat while trivalent plating eases installation and resists corrosion.
