Product description
Copper Plus motorcycle spark plugs have a copper core center electrode that allows for accurate control of heat range, optimizing performance, and longevity for the spark plug Fine wire electrodes increase ignitability by reducing spark quench
Increased bore clearances between shell and core nose reduces fouling caused by carbon deposits
Patented SAC-9 semi-conductor resistor for maximum EMI and RFI suppression
