NGK Laser Iridium Spark Plug Box of 4 (CR9EIA-9) for Select 2002-2019 Husqvarna, Kawasaki, Suzuki, Yamaha

Fits select 2002-2019 Husqvarna, Kawasaki, Suzuki, and Yamaha motorcycles.

NGK Laser Iridium spark plugs are engineered for riders seeking the highest levels of performance and service life. These OE-style plugs feature a laser-welded iridium-tipped center electrode and, in most applications, a platinum chip on the ground electrode. This dual-precious-metal design ensures a consistent spark while providing superior wear resistance—the iridium center electrode is six times harder than platinum, maintaining precise gap tolerances even under high-heat conditions.

Built with technical precision, these plugs utilize a 98% pure copper core to maximize heat dissipation, preventing pre-ignition and fouling. The high-grade alumina silicate ceramic insulator provides superior dielectric strength and thermal conductivity, while the trivalent metal plating protects against corrosion and ensures the plug remains easy to remove during the next service interval.

• Iridium Tip: Laser-welded center electrode provides exceptional durability and a fine wire design for improved ignitability.
• Platinum Ground Electrode: Features a platinum pad for even wear in high-performance and distributorless ignition systems.
• Superior Construction: Pure alumina silicate ceramic insulator for better heat transfer and structural integrity.
• Anti-Seize Finish: Trivalent metal plating eliminates the need for anti-seize during installation.
• Gas-Tight Seal: Triple gasket seals prevent combustion gas leakage.
