do you know what the part number for the OEM O2 sensor is?

Really? I've been generous with my time and thoughts. Perhaps you might want to take the initiative and do a bit of investigating on your own. You can get the part number from any of the OEM Mazda parts stores. Many Mazda dealers operate on-line parts sales. It is easy to look up.

Also, I believe I recently posted a link to the Edge Auto Sports website with the part number. Its right there on your other thread.

Gee, at least try, please? Ok? We get tired of spoon feeding people who expect to have others do everything for them. That's not how it should work here. It's not unreasonable to ask someone to try to do a bit of their own homework, and then if they really fail, to seek help.
