Bosch Platinum Plus Spark Plug

Bosch Platinum Plus Spark Plug


Pure platinum technology with a unique extended insulator design.

If you want to experience quicker starts, smoother acceleration and top fuel efficiency, Bosch Platinum is the spark plug for you. Only 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.
