Spark plug identification

[Boomyal]

While rooting around the garage for a set of plugs for my Suburban, I ran across a new set of eight Champion RV12YC Copper Plus plugs. My 'burb takes 17YC's so I know they are not for that.

Any ideas what they fit?

Re: Spark plug identification

Boom is that a surface gap plug (no electrode) ? And is it in a four pack ?

It is a 4 pack RP but looks like a standard plug . I'll check the link listed above.


OB, copy and paste works real good. Looks like it might have some ford 302 applications. That, amongst many uses listed, is the most likely reason that I would have had them.

Do marine engines use hotter or colder range plugs than their automotive equivalants?
