CHAMPION part description

A small fine wire center electrode reduces the voltage required to ionize the gap. Aids in low speed performance or borderline ignition output. May also "band-aid" other problems such as improper air/fuel mixtures or a weak ignition system. Constructed with a nickel shell for faster heat dissipation and copper core or double copper (when noted) for further heat removal, all racing plugs are non resistor (unless specially noted).
