That said, not trying to convince to use. Your vehicle, your call. For reference personally never used an RP filter. Btw, excluding purple color adbv, basically same if not identical Amsoil filters.
I've used them before and never had an issue. Amazon is sending a replacement so I can see if there is a difference. I agree, it's difficult to get good pictures but when I visually inspect, the inconsistency seems strange. Not bashing the RP product, just wanted to share to make others aware.
