High Performance Nickel Copper Spark Plugs for Motorcycle Ignition Systems

Premium nickel-copper alloy core ensures superior conductivity and heat dissipation, extending plug lifespan by 30% compared to standard models. Precision laser-welded electrodes resist corrosion and reduce misfires even in extreme temperatures (-40°F to 2000°F).

Optimized for high-compression engines, ideal for touring bikes, off-road motorcycles, and custom builds. Thread diameter 14mm with triple-seal gasket design prevents combustion chamber leaks.

Direct OEM replacement for 770050155 with 0.6mm iridium-enhanced center electrode for faster cold starts. Includes anti-fouling ceramic insulator to maintain consistent spark in stop-and-go urban riding.

Bulk pricing available for repair shops and distributors – meets or exceeds ISO 2704 standards. Ships globally with compatibility charts for major brands including Honda, Yamaha, and Ducati.
