Yes, they are built to OEM specs. Now, I have sent B/A e-mails requesting country of origin (parts) and they refused. Some auto parts are good. No complaints with their oil filters though. Good luck!
That doesn't surprise me. I suspect they don't want to commit to specifications, or even coo, as they want to keep their options open to change suppliers at any time. In fact, they may have multiple suppliers for the same items.
