Champion Spark Plugs / Typical and resistor types.
Motorcycle spark plugs Copper Plus feature a copper core in the central electrode, allowing precise control of the thermal range, optimizing performance and lifespan of the spark plug. Electrode with thin wire increases ignitability while reducing spark erosion.
The increased gap between the shell and the tip of the core reduces contamination caused by carbon deposits.
Patented SAC-9 resistor for maximum suppression of EMI and RFI.
