Original style Brass knurled spark plug nuts for Champion X & A25

These are a limited supply of an old reproduction that was made exactly the same as the originals. The Knurled edge is an exact duplicate.
Replaces your missing Champion-X or Champion A25 plug nuts. These nuts have the original 8/32” thread. (They will not fit Motorcraft, Autolite or any other model style plugs that have a different thread size.)
NOTE: They will also not fit on the early Champion X plugs that have a noticably thinner stub which measures 5/40" for these early plugs use part# 5201EN.
