Exclusive Bosch platinum technology with an enhanced design for 25% longer service life.
If you want to experience quicker starts, smoother acceleration and increased fuel efficiency, Bosch Platinum Plus is the spark plug for you. Only Bosch Platinum Plus features a platinum center electrode that's heat-fused into an extended ceramic insulator to eliminate air gaps which exist in platinum alloy-tipped plugs. And now Bosch Platinum Plus features a tapered, yttrium-enhanced v-profile ground electrode that extends the service life 25% longer than the original Bosch Platinum Spark Plug.
This superior design reaches its self-cleaning temperature faster. And with a lower ignition voltage requirement, Bosch Platinum Plus provides reliable starting in hot and cold weather extremes and provides a more reliable spark at higher RPM's without misfires.
