dealer tells me the left or rad side 02 is different from the right or firewall side one. looks to me like the oem difference is only the length of the cable but dealer says whole thing is different. does anyone know for sure if you can install a bw sensor in both applications even with the extra length of cable?
(i know the cat area sensor is totally different, but, thats not the issue)

 

I believe they're the same

 

They are the same sensor. Only the cable length is different.
