My generator manual is on the LD in storage. If you can wait a day or so, I'll check since we have the same generator. In the meantime, hope the following information might be helpful.
Onan 167-0275 Spark Plug For MicroQuiet 3600 and 4000 Generators (https://www.rvupgradestore.com/Onan-167-0275-Spark-Plug-p/55-9582.htm)
In addition, if you know the model number of the generator, any Cummins shop will have the correct parts.
I have the Cummins QG4000 on my 2016 MB. I used the NGK BPR5EIX-11 iridium plug on mine. They are a little more money than the OEM but just a couple dollars. Faster starts and runs good.
