New Old Stock Ford C-4 spark plugs made by Champion FoMoCo part number 19-12405-B. I believe these are correct for many 1920's 1930's and 1940's cars and trucks including Ford flathead V8 1932 and 1932 1933 1934 4 cylinder. You will receive what is pictured...4 plugs new in the original boxes. This particular set has the black annodized plug end and black ink stamps on the insulator. These also have brass plug wire ends. Nice addition to the nicest correct restoration.
