NGK Laser Iridium/Platinum Spark Plug Box of 4 (DILKAR6A11)

The iridium-tipped center electrode on these NGK spark plugs is six times harder than platinum, offering excellent durability and a consistently stable spark. This advanced design helps ensure reliable starts and optimal engine performance. They are built with a pure alumina silicate ceramic insulator, which provides superior strength and helps transfer heat away from the plug, preventing overheating. The trivalent metal plating on the exterior offers good resistance to corrosion and seizing, making installation and removal easier.

These NGK Laser Iridium spark plugs are designed as direct OE replacements, meaning they meet the original equipment manufacturer's specifications for a wide range of vehicles. The fine wire center electrode and a raised platinum pad on the ground electrode work together to provide even wear, especially in modern distributorless ignition systems. This setup contributes to improved spark performance over time. The copper core inside the insulator also aids in heat removal, further contributing to the plug's longevity and consistent operation.

NGK includes triple seals to prevent any leakage from the spark plug. This box contains four plugs, suitable for many 4-cylinder engines. They are a solid option if your vehicle originally came with OE DFE iridium alloy plugs, offering a good balance of performance and a long service life.
