Oxygen sensor ID?

[lasmariaspr]

For right sensor Bosch nr. is 0 258 005 327, oem nr. 11 78 1 401 276. For left sensor is 0 258 005 324, oem nr. 11 78 1 747 005 I have on my 1995 325is 0 258 005 324, no CAT is installed, do I have the correct OS?

I have only one installed!

Could their be a important difference if installed an incorrect oxygen sensor?

I don't know about the numbers. I have only one on my 95 325is. I do have a single cat. I just finished some research on the exhaust system on my car and it looks like its all custome from the exhaust manifold back so Im not a good reference point for this.

My cable on the OS is white, and in the photos I have seen are black, what color is yours?
