An OS is an OS unless you don't have one
My 97 suburban had been stripped of the cat converter and everything else had been worked around. I had to replace almost every sensor on it. This sensor surprised me when I put it in my intermittent misfire code went away. Of course I had to have plugs put in so the sensors could be installed, but it works great now. Love the shipping from these guys.
