NGK Laser Iridium Spark Plug Box of 4 (ZGR7GI-13G)

The iridium alloy center electrode in these NGK Laser Iridium spark plugs has an extremely high melting point, making it well-suited for today's advanced engines. These are actual OE replacement spark plugs, designed to offer a solid combination of performance and longevity. The pure alumina silicate ceramic insulator provides both superior strength and effective heat transfer, helping to prevent overheating and ensure reliable starts. You'll also find a platinum pad on the ground electrode, which helps promote even wear, especially in distributorless ignition systems.

NGK uses trivalent metal plating on these plugs, which offers good resistance to corrosion and seizing, making installation and removal easier. The copper core within the insulator aids in removing heat from the combustion chamber, and triple seals are incorporated to prevent any leakage. These plugs are a great choice when your vehicle originally came with fine wire iridium alloy plugs.
