quick o2 questions....

[Threeo2]

so I bought a couple of o2 sensors from two different stores because the first store only had one in stock.
I get home and notice one has a longer pigtail than the other and both have different part #s, but both are three prong.
Both are Bosch sensors. My question is, could I use these or did they give the wrong one? How do you know what sensor is for what side?

 

[cjones]

according to autozone they are interchangible(long and short pigtail). either one can go on either side.

They should both work on either side. If there is one that is a little tight, use the long one for that side.

I know I bought a few 02 sensors for my 98 (OBD II though), and it used the same Bosch part numbers for either side, and front or back. I know OEM, there is a difference between sides...

You could always take back one of them and get one of the same, if you can
