Advantages of Bosch plugs:
- First-class ignitability for high performance due to specifically developed precious-metal alloys at the center and ground electrode
- Outstanding engine protection due to nickel-plated housing and thread
- Hassle-free spark plug replacement due to factory-set electrode gap
- High wear resistance due to a highly heat-conductive center electrode
- Reliable thermal characteristics due to heat-shrink assembly
Service Suggestions:
Replace the whole set at once
Experience has shown that replacing the whole set of spark plugs is cheaper than having to replace them one by one. The operating conditions of an engine’s individual spark plugs are very similar – as it becomes apparent by their similar wear behavior.
Fast and correct fitting:
- Select the matching industrial spark plug from the range of products.
- Screw in the industrial spark plug by hand until it is seated tight at the cylinder head.
- Using a torque wrench, tighten each spark plug to the specified torque.
Torque: 33 or 50 Nm, with or w/out lubricantion.
The use of Bosch industrial spark plugs in engines with fuel-fed pre-chamber is not intended and not recommended by Bosch.

Re-gapping tool
Bosch re-gapping tool is a professional tool for accurate readjustment of the electrode gap of Bosch M18 Iridium industrial spark plugs.
During their operation, industrial spark plugs wear off as the electrode gap increases. This results in misfires. Bosch Iridium M18 industrial spark plugs were developed in such a manner as to allow electrode re-gapping by means of the Bosch re-gapping tool.
