I just bought 2 new o2s and they dont look the same? Should it be like this or is one of them wrong? They are booth AC Delco and booth has the AFS75 partnumber which I believe is right for my car.


You can see the difference here


They did come in different package, the one in the middle came in the box to the right.. But still same partnumber




Thanks!

 

When I bought my front O2 sensors they both came in the package on the left. My assumption is that the one on the right is just a different design, be it older or newer, that they happened to send you. If you have a real doubt about the sensors, I would contact who you bought them from.

 

Thanks, if they are the same just different design then no problem for me. Just want to make sure it´s ok to use them. Guess I will contact where I bought them from, just wanted to check with you guys if someone knows for sure!

 

I just bought a pair at autozone and there was one of each design in identical boxes. I didn't like the fact that they didn't exactly match, so I had them get another one so I had a matching set that looked like the ones in the left of your picture. I think I chose that one because it was a little shorter and wanted all the clearance I can get with my LT1 into 3rd gen swap.

 

Was that ac delco also? I feel the same, kind of dont like that they doesent exactly match Would have been much easier if I just got 2 of the same

 

I used to have 2 of the ones on the left. I just ordered a new pair about a month ago and got 2 of the ones on the right. I'm sure they're interchangeable, afterall they're both going to output the same parameters.

 

Nice! Makes me feel better about them. I guess as long as they are delco and have the correct partnumber on them I should be fine.

 

The one on the right looks like a Delphi new style.

 

Should be equal then! Thanks
