Bosch Platinum features a pure platinum center electrode that's heat-fused into an extended ceramic insulator to eliminate air gaps which exist in platinum alloy-tipped plugs. This superior design reaches its self-cleaning temperature faster. And with a lower ignition voltage requirement, Bosch Platinum provides reliable starting in hot and cold weather extremes and provides a more reliable spark at higher RPM's without misfires.
