The shop checked my rig and say my O2 sensor is intermittently failing and needs replaced. I asked an online parts help person and they recommended a 4 wire Bosch 15703 part.

I went online to order the part but when I entered my vehicle I get more choices....3 wire, 4 wire, upstream, downstream. I don't want to have to ship a part back because it's wrong.

Can anyone confirm this is the correct part or whether I need to be ordering 2?

Thanks!

Welcome to AF. How do we know which one has failed, what was the code?
