Hey all. I try as much as possible to buy American made products. Most Napa oil filters used to be USA made, but my last purchase of one of their pro-select filters wast made in Vietnam, and from a different manufacturer than than the old ones I still had in stock with the same part number. The threads were wrong and would not screw on. My question, short of going to auto parts stores and reading the box, are there any oil filters that are usually made in the USA?
