WIX just adds a "5" in front of the NAPA number so WIX 51080 = NAPA 1080 which is what I used in the 1941 factory-installed filters on senior engines and assume 1940 is the same and the juniors are probably the same if also factory equipment; I used the same 1080 right thru 1950 on my Custom 8. However if you have a dealer-installed filter or some later installation it may take a different cartridge.
