Iridium’s superior durability means less wear, longer service intervals, and reliable ignition even under extreme conditions. Key benefits over standard plugs:

Stronger spark for improved combustion and throttle response
Better fuel efficiency and smoother running
Easier cold starts
Longer lifespan thanks to iridium’s high melting point
Reduced misfires and consistent performance under load
