Fused Platinum and Iridium Copper Core Spark Plugs

Bosch Industrial Series Spark Plugs are the right plugs for your industrial applications.

Bosch Industrial Series Spark Plugs combine over one hundread years of spark plug engineering experience with robust construction of the highest quality heavy duty components. The result is a superior platinum/iridium spark plug which exhibits unsurpassed reliability and a greatly extended service life. Precious metals in both the center and the ground electrodes provide exceptional resistance to wear.

The highest level of innovation has been applied to every facet of the design and construction of Bosch Industrial Series Spark Plugs. Specifically developed to withstand harsh operating conditions, the Industrial Series is engineered to be the most advanced spark plug on the market.

Feature Benefit
Fused Platinum and Iridium copper core center and ground electrodes Provides superior wear, durability and a consistent level of performance over the life of the plug
Electrode seal and graphite/metal/glass fused resistor Provides a more consistent resistive value than pre-manufactured resistors. Prevents "blow by" of combustion gases and a change in heat range over time
Nickel-plated steel shell Robust construction helps control shell deformation under torque, and provides corrosion resistance
Pyranit Insulator Exceptional heat transfer properties. Prevents misfire due to current leakage and improves resistance to combustion deposits
Full length terminal stud and threaded brass terminal nut Provides a corrision and vibration free connection, optimum conductivity and maximum structural integrity

Combustion Monitoring

7330 Combustion Sensor

Also included in the Industrial Series is the 7330 Combustion Sensor for Caterpillar G3600 series engines. This sensor immediately alerts the engine management at the first sign of abnormal combustion. The same robust construction and innovative design found in the 7301 spark plug can be found in this Industrial Series combustion sensor.
