The NGK Laser Iridium spark plug, packaged in a box of 4, combines longevity and stable ignition for modern engines. An iridium-tipped fine wire center electrode is exceptionally hard—reported up to six times harder than platinum—while the copper core and pure alumina ceramic insulator manage heat and dielectric performance. Many versions include a platinum pad on the ground electrode for even wear in distributorless systems.
