Oxygen sensor upstream
5 Answers
What is the difference between these 2 upstream o2sensors? Can you replace the one with the other one?
This one is the one I got to use as a replacement but not sure it will work in place of the original factory one?!
Use the correct one or your car will not run right. If the plugs match up and the sensor looks the same then it should work.
It looks like it’d match up from the pictures but towards the plug, the wires are covered on the original and not on the one I just purchased.

I have found there are differences between the 2.0L engine in the Elantra and the Elantra GT. First noticed it with the air filters. Guessing from your photos the same with the O2 sensors but whoever is selling the parts is either is missing that or the parts in their system do not specify and breakdown by model trim level.
