I can't speak to the specific Mexican made Amsoil filter because I've not seen one cut open. Otoh, I have seen examples of other filters that had been made in US, moved to Mexico and quality suffered. Some Bosch Premium 3323 as well as 'some' Wix. Also personally seen where the Gonher made Nissan OEM has an adbv defect that can allow oil bypass.
That said, I'm not going to condemn the Amsoil filter or any filter without seeing it. Could be just fine, just a different coo.
