Q: Since the part numbers look correct，will they fit my 2003 tahoe?

They were a exact fit for my 2003 Silverado's 4.8. I believe this item would fit being the vehicles are basically the same.

Q: which is up stream and downstream?

All 4 oxygen sensors are the same. The upstream and downstream also are the same.
