The NGK SILZNAR8C7H Laser Iridium Spark Plug sets a new standard for ignitability and durability in automotive spark plugs. Featuring a fine wire iridium-tipped center electrode and a fine wire platinum-tipped ground electrode, these spark plugs ensure a slow wear rate, providing stable idle, superior anti-fouling characteristics, enhanced fuel efficiency, and lower emissions. Trivalent metal plating enhances anti-corrosion and anti-seizing properties, extending the plug's lifespan and reliability in various environmental conditions. Corrugated ribs prevent flashover, maintaining consistent spark performance. The pure alumina silicate ceramic insulator provides exceptional strength and efficient heat transfer, while a copper core facilitates effective heat dissipation. Additionally, triple seals prevent leakage, ensuring long-term performance and reliability. NGK's commitment to quality craftsmanship makes the SILZNAR8C7H Spark Plug an ideal choice for drivers seeking enhanced engine performance and environmental sustainability.
