NOS Sparkplugs

[Oli-V]

If there are some knowledgeable people out there that know what tractor or old motors use these sparkplugs, fill me in. They are Co-op brand and I have C2M, C-48, C-2, and Z7. They are all unused. My uncle must have gotten them at a auction many years ago.

If u post a pick of them plugs makes it a lot easier to tell what they will fit.

Those C-2 plugs look like Champion X plugs for something like a Model T, etc.
The o-com plugs could be a Champion 3x.
The C-48 maybe a flathead V8? I don't know.

C-2 will fit the My Fordson Model F tractor.

C-2 will fit a John Deere D and GP.

What years and models would those be? In general...

Farmall MD, Super MD, 400D, 450D, IH W400D, W450D, McCormick WD-6, Super WD-6. If that includes the “9” series then add IH 600D, 650D, McCormick WD-9, Super WD-9 maybe WK-40. TD-6 & 9 crawlers should be in there to, sure I missed some. Look them up on Tractordata if you want the years made.

D89D plugs are commonly used in Fairbanks and Morse engines used in oilfield pumping engines. They have extended electrode to help with fouling problems.
