Champion spark plugs / Standard and resistor types - copper plus CJ8

Copper Plus motorcycle spark plugs feature a copper-core centre electrode allowing precise thermal range control, optimising spark plug performance and longevity
Fine wire electrodes increase ignition capacity by reducing spark expansion
Greater clearance between the housing and the central electrode insulator reduces carbon deposit build-up
The patented SAC-9 semiconductor resistor allows maximum EMI and RFI suppression
