    I bought my Motorcraft ones off rockauto.com. Only changed the front ones since my rear sensors are turned off via the tune.

    Upstream is considered the front/first set
    Downstream is considered the rear/second set

    Bank 2 refers to the opposite side of the engine the 1st cylinder in the firing order is located. Sensor 1 refers to the 1st O2 sensor.

    Funny thing is Bosch makes 85% of all O2 sensors on the market, the ones with the Bosch name pass the most stringent testing, the ones that fail are then sent back through the process, re-tested at a lower standard, passed, and sold as aftermarket. I know this because my wife runs the test line.

    So can you get confirmation whether Bosch makes Motorcraft O2 sensors?

    The last set of Motorcraft O2 sensors I bought looked identical to a new set of NGK sensors I had. And I do mean identical. Currently I'm running NGK O2 sensors in all three of my Panthers with no problems at all.
