The NGK Laser Iridium spark plug combines iridium durability with high ignitability for drivers seeking longevity and stable spark performance. A fine iridium tip provides superior wear resistance, while NGK's alumina silicate ceramic insulator and copper core help manage heat. Many Laser Iridium plugs incorporate a platinum pad on the ground electrode for even wear, and trivalent plating plus triple seals aid corrosion resistance.
