The Bosch 7341 M14 industrial spark plug has all the technical benefits of the M14 EVO design, combining proven reliability features while conserving cost benefits of high Platinum alloys. Modern gas engines need to meet increasing demands. They are judged based on factors such as fuel economy, low emissions and efficiency. Many engine manufacturers rely on the high quality, reliability and performance of Bosch industrial spark plugs for their gas engines. The new M14 industrial spark plug 7341 from Bosch has been especially developed for the use in such kind of engines. Selecting the right spark plugs is essential and in order to create clarity there, Bosch has decided to apply the new type formula format also to the 7341.

Advantages:

1. Increase in service life of industrial spark plug due to reduced breakdown voltage
2. Increased mechanical robustness through improved design
3. High wear resistance due to a highly heat-conductive center electrode
4. First-class ignitability for high performance due to specifically developed precious metal alloys at the center and ground electrode
