Default identical O2 sensors?

Hey guys, i have to replace both of my air fuel ratio sensors (bank 1, 2, sensor 1) for my 2007 LS.

Now, are those sensors identical for both bank 1 and 2?, let's say can i just buy 2 identical sensors?

i found this oem Denso 234-9052 sensor but it says it's for Left and now im confused.

thank you guys.

The part numbers are different but they might be the same exact thing except that the harness is different for each one.

Curious, how many miles were on your car when they failed?
