What did you want to replace? Upstream or Downstream? Maybe you got them reversed.

I always use the Denso 234-4669, if you are talking about Upstream. I have never replaced downstreams since I have longtubes and don't use them.

This is the listing I have bought them from twice. They look just like the picture: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Yeah that's weird. I would be concerned too, but hopefully it's just some sort of updated part revision.

I know there is some laser etching on the side of the sensor, but I don't know if it has the unique part number on it. Have you checked to see if it does? Maybe some sort of identifier you can cross reference back to the part # you ordered.

The number that came up on the original denso one cross referenced to a ac delco lol but then the delco cross referenced to the denso.. im pretty sure it might have revised it or superseeded

Lol figures. Ok cool, at least it seems legit. I guess the true test is when you put it in.
