NGK SIMR8A9 Laser Iridium Spark Plugs are engineered for peak performance and longevity. Featuring a fine wire iridium-tipped center electrode and a fine wire platinum-tipped ground electrode, these plugs ensure superior ignitability and a slow wear rate, maintaining stable idling, superior anti-fouling capabilities, and contributing to enhanced fuel efficiency and lower emissions. The plugs are further enhanced with trivalent metal plating for superior anti-corrosion and anti-seizing properties, corrugated ribs to prevent flashover, and a pure alumina silicate ceramic insulator for strength and efficient heat transfer. A copper core aids in heat dissipation, while triple seals prevent leakage, ensuring reliability and longevity in various driving conditions. These features make the NGK SIMR8A9 ideal for drivers seeking optimal engine performance and environmental responsibility.
