The NGK Laser Iridium Spark Plug - DIFR6C11 is engineered for superior ignitability and extended service life. Featuring a fine wire iridium-tipped center electrode and a fine wire platinum-tipped ground electrode, it ensures a slow wear rate, providing stable idle, superior anti-fouling, improved fuel efficiency, and reduced emissions. Trivalent metal plating on the threads and shell offers excellent anti-corrosion and anti-seizing properties. Corrugated ribs on the insulator prevent flashover, maintaining consistent spark delivery. Its pure alumina silicate ceramic insulator provides superior strength and efficient heat transfer, while the copper core aids in effective heat dissipation from the electrode. Triple seals prevent leakage, ensuring reliable performance under diverse operating conditions. Ideal for engines requiring high-performance spark plugs, the NGK DIFR6C11 delivers exceptional reliability, efficiency, and longevity.
