NGK Laser Iridium High Ignitability spark plugs are engineered to meet the demanding requirements of modern OE applications, balancing high-performance combustion with long-term durability. These plugs feature an iridium-tipped center electrode—a material six times harder than platinum—paired with a raised platinum pad or fine wire tip on the ground electrode. This combination ensures consistent spark performance and even wear, specifically in high-demand distributorless ignition systems.

  • 98% pure copper core provides superior heat dissipation to prevent overheating
  • Fine-wire iridium center electrode offers maximum ignitability and service life
  • Pure alumina silicate ceramic insulator ensures high dielectric strength and heat transfer
  • Trivalent metal plating provides excellent anti-corrosion and anti-seizing properties
  • Triple seals eliminate the risk of combustion gas leakage
  • Manufacturer Part Number: SILKGR9A7ES
  • Quantity: Set of 4 spark plugs
