The Wix/NAPA spin-on oil filters for my Elantra are made in Mexico. Microgard (made by Wix) is made in USA though. It is true that I would have preferred it if Wix had continued to make all of their spin-on oil filters in the USA, but from what I understand, the Wix spin-on oil filters that are made in Mexico are good quality filters (equal in quality to the USA-made filters).
