I need to replace my oxygen sensor at b2/s1. When getting the part, do I ask for upstream/downstream, etc?

Part number would be appreciated as well.

What year and engine size would help? B2S1 means, upstream left.

It is a 2004 Sedona 3.5L. When you say left, is that in the front of the engine?

39210 39600 is the Kia part #. Yes, left towards the radiator.
