NGK Laser Iridium spark plugs (box of 4, IKER7A8EGS) pair an iridium-tipped fine wire center electrode with a high-grade alumina ceramic insulator and a copper core for reliable starts and heat control. Iridium offers far greater hardness than platinum; many NGK Laser Iridium plugs also incorporate a platinum pad on the ground electrode for even wear in distributorless systems, plus corrosion-resistant plating and triple-seal construction.
