Fits 2016-2020 Honda CRF1000L/CRF1100L Africa Twin and 2019-2020 Honda Talon 1000R/1000X/1000X-4 models.

NGK Laser Iridium High Ignitability spark plugs are engineered to provide the ultimate combination of performance and service life for high-output Honda powersports engines. These plugs feature a fine-wire iridium-tipped center electrode paired with a raised platinum pad on the ground electrode. This dual-precious-metal construction ensures consistent spark delivery and extremely high durability, even in the high-heat environment of modern distributorless ignition systems.

• Iridium Center Electrode: Delivers a center electrode material six times harder than platinum for maximum longevity and stable ignitability.
• Platinum Ground Electrode: Features a raised platinum pad for even wear and improved spark performance over the life of the plug.
• Copper Core: The 98 percent pure copper core facilitates rapid heat dissipation to prevent overheating and reliable cold starts.
• Alumina Silicate Ceramic: High-grade ceramic insulator provides superior dielectric strength and thermal conductivity.
• Trivalent Metal Plating: Offers specialized anti-corrosion and anti-seizing properties to protect the cylinder head threads.
