NGK Laser Iridium Spark Plug Box of 4 (IJR7A9)

This product is a box of four NGK Laser Iridium spark plugs, part number 7901. These are designed as direct OE replacements, meaning they are built to the same standards as the original plugs that came with your Honda TRX500FA FourTrax Foreman Rubicon. They feature a fine wire center electrode made from an iridium alloy, which is known for its high melting point and durability, offering a stable spark for consistent engine performance.

The pure alumina silicate ceramic insulator helps with heat transfer and provides strength, while the trivalent metal plating on the exterior helps prevent corrosion and seizing, making future removal easier. A platinum pad on the ground electrode ensures even wear, especially in modern ignition systems. The copper core inside helps manage heat, preventing the plug from overheating, and triple seals are used to prevent any leaks.

NGK designed these plugs for vehicles that originally came with fine wire iridium alloy plugs. If you're looking to maintain the original performance and longevity of your engine, these NGK Laser Iridium plugs are a solid option.
