Longer performance life

The Bosch Advantage:
Four ground electrodes provide multiple spark paths which allow the spark to travel the most efficient path and deliver a longer and more powerful spark than conventional single electrode plugs. This offers superior burn characteristics for ultimate engine performance.

The Bosch Advantage:
Only Bosch uses a pure platinum center electrode that's heat-fused into a ceramic insulator to eliminate air gaps which exist in platinum alloy-tipped plugs. Platinum+4 reaches its self-cleaning temperature faster for smoother acceleration and better fuel efficiency. Plus, Platinum+4 adds 75% more pure platinum over that of Bosch Platinum to its center electrode, providing a longer performance life.
