The new Champion® FB-M18 Iridium spark plug, designed for large stationary engine applications running compressed natural gas (CNG), landfill-gas, or biogas fuels brings a combination of extended life and low cost to the power generation sector.

 

Key features of the FB-M18 include an enlarged iridium alloy, thin-walled nickel, copper-cored center electrode, which provides greater durability through improved heat release and best-in-class wear characteristics. The plug assembly is sealed using Industrial Fired-In Suppressor Seal (IFISS) core technology, combined with a hot lock shell seal to give improved sealing, especially at high cylinder temperatures and pressures.  Hot lock technology also provides a high resistance to shell fracture during engine assembly or disassembly.
