Champion Spark Plug for motorcycles with a copper core in the center electrode. Its features include:

• Precise control of the temperature range that optimizes performance and spark plug lifespan.
• Fine wire electrodes that increase ignitability and reduce spark attenuation.
• Reduced contamination from carbon deposits due to increased distances between the housing and the tip of the core.
• Patented SAC-9 resistor semiconductor for maximum EMI and RFI suppression.
