    Why choose iridium spark plugs?

    As an important part of the gasoline engine's flameout experience system, spark plugs directly affect the engine's operating efficiency and the vehicle's driving experience. Spark plug materials come in a wide variety of materials. From affordable nickel alloys to platinum and iridium with excellent performance. Although nickel alloy spark plugs are affordable, they have limited high temperature resistance and corrosion resistance, and have a relatively short service life; spark plugs made of precious metals such as platinum and iridium have good conductivity and corrosion resistance, higher ignition efficiency, and durability. Stronger, suitable for car owners who have certain performance requirements, and also standard equipment for high-performance models.

    The spark plugs are iridium spark plugs. During the production process, the factory strives for excellence just to produce better spark plugs.
