Oxygen Sensor (Bank 1 Sensor 2)

Need to replace the oxygen sensor in my 2011 958-S in position Bank 1 Sensor 2, but having difficulties finding which product online would be compatible.

From my understanding, I believe Bank 1 Sensor 2 would mean it’s on the driver side (cyl 1-3) in downstream position which would be after catalyst, but I’m not able to find any research that definitely confirms this fact.

I don’t know if a regular Bosch Downstream Oxygen Sensor that’s compatible on both sides would work in my situation or if I need one that specifically states “Left” AND “Downstream.”

Anyone with expertise that can provide details or assistance on the matter so I can place the correct order?
