Four Times the Amount of Pure Platinum with Four Electrodes and the Most Powerful Spark.

Bosch Platinum+4's unique revolutionary firing technology combines the advantages of surface air gap technology, four ground electrodes, and a heat-fused center electrode with four times the amount of pure platinum. Only Bosch offers this revolutionary firing technology for the ultimate in engine performance.

Unlike conventional air gap spark plugs, Platinum+4 uses surface air gap technology, which generates the most powerful spark you can buy. The spark first travels over the surface of the insulator nose and then arcs across the air gap to a ground electrode for a longer spark without increasing the voltage requirement.

Plus, four ground electrodes provide multiple radial spark paths, which allow the spark to find the most efficient path. Platinum+4 also uses four times the amount of pure platinum in its center electrode versus Bosch Platinum, and double that of Bosch Platinum2, for the longest performance life.

Try Bosch Platinum+4 Spark Plugs, and ignite your motorcycle's performance with the most powerful spark you can buy.
