I do not understand what you mean by low deviation... What load are the units running at and how is the load sharing being done.. The use of J type plugs will increase the fuel consumption of the unit.. Please clarify..

The multi torch spark plug used in the C and E model engines were to help meet the emissions goals. I know several overseas (from USA) operators using J gap plugs with no performance issues. BUT, the ignition energy display is not accurate and you may find the need to change the timing a bit (advance) if the full load exhaust port temps get too high.
When you remove the failed spark plug from the engine do you see deposits at the ports of the spark plug prechamber?
Usually short life of prechamber spark plugs is due to operating the engine long times at low load levels (less than 45% of rated load), a lube oil with too high ash content, impurities in fuel gas or running beyond recommended major maintenance intervals for top-end and overhaul.
Hope that helps.

Please do not use j-type spark plugs in g3500c series to overcome the problem of low deviation.
Check your fuel pressure low fuel pressure & wrong emission setting is the root cause of low deviation.
J- type spark plugs produces single direction flame which can damage your cylinder head after some operational hours.
So to avid of crack of cylinder head please do not use the j- type spark plugs in g3500c series.
