Revolutionary firing technology
delivers the most powerful spark!
Bosch Platinum +4 Spark Plugs are designed with a revolutionary firing technology that provides multiple spark paths to deliver the most powerful spark. With four ground electrodes, not only does the spark find the most efficient path, but it is longer and more powerful with less interference and optimal access to the fuel/air mixture. Bosch Platinum +4 adds 75% more pure platinum to its center electrode, providing longer life and optimal performance to the spark plug. With Bosch Platinum +4 Spark Plugs you'll get quicker starts, smoother acceleration, and improved fuel efficiency.
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.
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.
