About this product
The NGK JR9B spark plug delivers reliable ignition and performance for your motorcycle. Featuring advanced materials and construction, this spark plug ensures efficient combustion and long-lasting durability.
Description
The NGK JR9B spark plug is engineered for optimal performance and reliability.

The pure alumina silicate ceramic insulator provides superior strength and enhanced heat transfer, preventing overheating and maintaining consistent spark. Triple seals prevent leakage, ensuring reliable performance in demanding conditions. Corrugated ribs minimize flashover, and the copper core efficiently removes heat, contributing to improved engine performance and longevity. With a 0.7 mm spark gap and resistor type, this spark plug is designed to meet the specific requirements of high-performance engines. The 12 mm thread size and 19.1 mm (3/4") thread reach guarantee a secure and precise fit.
