Iridium, rated 6.5 on the Mohs hardness scale, is the second-densest element after osmium and the most corrosion-resistant metal\u2014even at temperatures up to 2000\u00B0C. Its exceptional electrical conductivity makes it an ideal material for high-performance spark plugs.\n\nA laser-welded platinum disc on the ground electrode enhances durability, significantly reducing wear and further extending the plug\u2019s lifespan. With both electrodes working efficiently together, the engine benefits from a more stable idle, improved fuel efficiency, lower emissions, and strong anti-fouling properties.\n\nAdditionally, the ground electrode features a taper-cut design to minimize flame quenching by reducing obstruction to flame expansion ;
