Use a spark plug cross reference chart to try and find it, google brings up quite a few, but why not use the original 167-1638 plug found here for about $4.79Onan spark plug

I searched for a sub awhile back and decided to stay with the OEM. It was easier to find and not a long wait.

I see it is about $7 on Amazon with free 2day Prime shipping.

I have used this site for all three filters and plugs: Onan Store

Look on your spark plug probably a champion number and then cross that number or  use The champion number. Any auto supply will have what you need.
