Spark Plug Original Number to Current Number

Recommended Posts

Could someone tell me the current spark number from the original number . Originally it was a Champion C -7 . It was installed in the 1931 Reo Royale 8 cylinder motor . What current spark plug would be the proper spark plug number to use for a replacement .

My 1995 Champion catalog says 1928-1935 Reo all models stock #516, plug # D16 .025 gap. Champion plug # C7 obsolete is replaced by plug #RD16. You can probably find one of these somewhere. It doesn't say so but i'll bet UD16 a booster gap plug would also work.
