NGK Laser Iridium Spark Plug SILMAR9A9S sets the standard for ignitability and longevity. Featuring a fine wire iridium center electrode and platinum-tipped ground electrode, it ensures a slow wear rate, promoting stable idle, superior anti-fouling, enhanced fuel efficiency, and lower emissions. Trivalent metal plating provides excellent anti-corrosion and anti-seizing properties, while corrugated ribs prevent flashover. Its pure alumina silicate ceramic insulator enhances strength and heat transfer, supported by a copper core that aids in heat dissipation. With triple seals to prevent leakage, this spark plug delivers consistent performance and reliability, making it an ideal choice for high-performance engines.
