Bosch Spark Plugs

Bosch heavy duty copper core plugs deliver excellent mileage and long life at a reasonable price. The Platinum plugs have a very wide operating heat range, withstand high temperatures, and last even longer. In Bosch numbering, the higher the number, the hotter the heat range of the plug. Modified engines often need a cooler heat range plug.
