Well-known member
I have a set of Champion C5 spark plugs. Although similar in appearance to the recommended version
which I believe are 3X (superseded by C16C); are they suitable for a standard unmodified 1932 Model B ?:):):)

The key is the length of the insulator. Without that information, it's hard to say, but I've not heard of a C5 plug being used on a Model B engine. The first replacement for the 3X plugs was the C4 plug released for all Model B engines in October, 1932.
