The Champion RHM78WPCC Platinum Power is a spark plug with a platinum-tipped centre electrode, designed for a stable gap and consistent ignition.
Platinum resists the erosion that widens the gap on a nickel plug. The spark plug is specified as original equipment on many vehicles and as a long-life upgrade over the equivalent copper plug of the same heat range. It is discontinued and no longer manufactured.
