I ordered 3 Motorcraft filters at different times from the same Amazon Prime link with high reviews. They are FL-500S for a 3.5 Ecoboost. One looks completely different from the other 2 and I'm wondering if it was a Motorcraft design update or one of the types is fake. The main difference is one has the 30 flute top and the others have the 14 flute top. One has a sticker and one has printing directly on can. Looking online I've seen both types of fluting on the ends on legitimate Motorcraft oil filters hence why I think there is a chance they're all real and either vary or were updated from one design to another. Anyone have any experience with this?
