..anyone know what it is?

Search didn't bring up the info I was looking for, and the WSM doesn't list the size.
Based on the fasteners I have on hand, it appears to be M14 1.5, but its hard to tell.
I'll be plugging it, and don't have the sensor to measure or use as a plug.

TIA

 

For future reference, it's M14 1.5 . I picked up an oil drain plug at the local auto parts place and it threaded in.

 

Thanks!
