3 x spark plugs

[M.W.Miller]

Hello, I purchased some boxes of model A parts, And included were four 3 x champion spark plugs still in the boxes and rapped in the wax type paper. They look like Nos. I know that these are now being reproduced and are very authentic to the originals. Just wanting to know if there is a way to tell originals from the after markets. Thank you. ..Mike

Reproductions...aren't they all still made by Champion?

These are reproduction the electrode goes all the way through the top

Besides the 3, reproduction bases have a fine internal knurl with 2 unknurled bands.

Bases with the correct coarse knurl and no bands are available from the parts dealers.

Here's a little trivia for you;

Ever notice on the BOX of a NOS 3X spark plug the "3" has a flat top while on the Repro BOX the "3" has a round top? The opposite what the plugs have. Weird, eh?
