The NGK 5066 Laser Iridium Spark Plug - DIMR8A10 is engineered for superior ignitability and extended service life. Its fine wire iridium tipped center electrode and fine wire platinum tipped ground electrode ensure a slow wear rate, providing stable idle, superior anti-fouling, improved fuel efficiency, and lower emissions. The spark plug is equipped with trivalent metal plating for excellent anti-corrosion and anti-seizing properties. Corrugated ribs on the plug prevent flashover, maintaining consistent spark delivery. A pure alumina silicate ceramic insulator enhances strength and improves heat transfer efficiency, crucial for engine performance and longevity. Additionally, a copper core aids in effective heat dissipation, contributing to overall engine efficiency. Triple seals on the spark plug prevent leakage, ensuring reliability under various operating conditions. Engineered to meet NGK's rigorous standards, this spark plug is an excellent choice for maximizing engine performance and durability.
