In the meantime, hope the following information might be helpful.Onan 167-0275 Spark Plug For MicroQuiet 3600 and 4000 GeneratorsIn addition, if you know the model number of the generator, any Cummins shop will have the correct parts. 1 Likes
Re: Spark plug Reply #2 – November 09, 2022, 01:06:36 pm 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. 1 Likes
