I just want to make sure I get the right O2 Sensor. The part # that I have for the front O2 is #25312184. Does anyone know if this is the right one for our cars? Is there any advantage going GM over any other aftermarket piece?

TIA,
John.

 

No, that sensor is for a 94-97 F-body. 25312196 are the right bank sensors and 25312197 are the left bank sensors for a 98 Z28. So, front and rear aren't as important as left to right. BTW, I work in parts at a dealership and I'm at work now in case you wonder how I got the numbers.

 

There is not a bit of difference between the left, right, front or back, as far as performance. The plugs are the same. The only difference is the length. So go with the one that is cheapest & fits the length you are looking for. Stick with the GM ones.

 

Sounds good guys. Thanks for the quick replies. I appreciate it.

John.

 

how much would 2 O2 sensors run me?
