OK the Napa Gold is identical to my Japanese made OEM in my Miata. The OEM from the dealers has less pleats therefore less filter area. This looks to be a very good filter for the miata for sure. Not sure if that would translate to all cars but should. Oh and it has almost the same part number as the Wix. Napa Gold was FIL2486 Wix was 42486.
