McCormick Deering 10-20 spark plug

daynee · Mar 1, 2011

I have a McCormick Deering 10-20, it has 1com champion spark plugs in it, and I know those cannot be the ones from factory. I would think it would be Edison spark plugs from factory and if so, what would the serial number on the spark plugs form factory.

Thank you for your time

Daynee, I have seen 1com champion plugs with the
IHC logo on them. I would think that was from factory. Todays plug in champion w-20 or w-18

Yeah, i think 1 coms were pretty much. I think the 20 Champion came later. I like the looks of the W20 as they have a large porcelain with the old look
