NGK Laser Iridium Spark Plug (DILFR7B10G)

This product includes a box of four NGK Laser Iridium spark plugs, part number 97218. These are designed as direct replacements for your vehicle's original equipment, offering a good balance of performance and how long they last. They feature an iridium-tipped center electrode, which is significantly harder than platinum, contributing to their durability. The pure alumina ceramic insulator helps manage heat effectively, and the trivalent metal plating on the exterior helps prevent corrosion and seizing during installation or removal.

The fine wire design of the center electrode ensures a consistent and stable spark, which is important for efficient combustion. This design, along with a platinum pad on the ground electrode, helps them wear evenly, especially in modern ignition systems. The copper core inside the plug also aids in removing excess heat from the combustion chamber, preventing overheating. These plugs are built with triple seals to prevent any leaks.
