Bosch Industrial Series Spark Plugs are the right plugs for
your industrial applications.
Bosch Industrial Series Spark Plugs combine over one hundred 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 ground electrodes provide exceptional resistance to wear.

Bosch Industrial Series Benefits |
|
|
Fused Platinum and Iridium center and ground electrodes |
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; prevent misfire due to current leakage and improves resistance to combustion deposits |
|
|
Full length terminal stud and threaded brass terminal nut |
Corrosion and vibration free connection, optimum conductivity and maximum structural integrity |

Combustion Monitoring
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 7306 spark plug can be found in the Bosch Industrial Series Combustion Sensor.
Engineering—the Bosch way
Bosch state-of-the-art R&D centers develop the technology that delivers the performance you expect from a Bosch spark plug.
Production takes place in the most sophisticated manufacturing facilities in the world, where Bosch quality control standards assure that every plug bearing the Bosch name earns it.
