About this product
Champion CJ8 spark plugs are engineered for optimal performance and longevity in motorcycle engines. These spark plugs feature a robust design and high-quality materials, ensuring reliable ignition and consistent engine operation.
Description
The Champion CJ8 spark plug utilizes a copper core center electrode to provide precise heat range control, maximizing both performance and spark plug life. Fine wire electrodes enhance ignitability by minimizing spark quench, leading to improved combustion efficiency. Increased bore clearances between the shell and core nose reduce fouling from carbon deposits, maintaining consistent spark quality. Equipped with a removable nut terminal configuration, these non-resistor type plugs offer versatile compatibility. With a 14 mm thread size and 9.5 mm thread reach, the Champion CJ8 is suitable for a wide range of motorcycle applications. The 0.6 mm spark gap ensures consistent and reliable ignition under various operating conditions.
