Think of yourself sitting in the drivers seat of your crossfire. The RIGHT side of the car is the passenger side; the LEFT side is the drivers side. I believe all cars are the same as to right and left.
The O2 sensor "BANK" is numbered as to the location of the #1 cylinder; Bank number 1 is the same side of the engine as is the number 1 cylinder, which on the Crossfire is the right (passenger) side of the car. O2 sensor bank number 2 is the other side of the engine. On the Crossfire it is the left (drivers) side of the car and the engine has cylinders #4, 5 & 6.
Some engines would have number 1 cylinder on the left side and thus O2 sensor bank 1 would be on the left side of the car, but not the Crossfire. "Bank" 1 is on the right (passenger) side of the Crossfire. THUS; "Right Downstream" means the right (passenger) side of the car. The right side of the engine and the right side of the car are one in the same. It has nothing to do with the hood up looking at the engine. I think that answers your question.
The information as you have it written in your post #1 I believe is correct as to Bosch numbers and the location.
