The NGK Laser Iridium spark plug set (box of four) pairs a fine-wire iridium center electrode with a raised platinum pad or platinum fine wire tip on the ground electrode to deliver high ignitability and longer tip life. NGK’s pure alumina ceramic insulator and 98% pure copper core aid heat transfer and reliable starting. Recommended for OE-spec iridium plug replacements, these plugs feature triple seals to prevent leakage.
