Is the upstream for 2003 chevy silverado 1500 5.3 the same part # as the downstream?

they are diffrent in design yes the 2 upstream are bank 1 sensor 1 & 2 downstream are bank 2 sensor 1 & 2

I've seen this described as a "male connector".. but isn't that a female? It looks like something goes IN the white part??

No this is consider a male connector.

Does it have the connector already on the wires?

Yes. The plug is already spliced in just like a factory unit. Completely plug and play install.

I have a 03 silverado. i wanna replace all 4 o2 sensors. guy at autozone said i need 3 of this part number and the center ones different?

My 05 5.3 Silverado called for all four of them to be this part number. I installed them and everything has worked perfectly since!
