Do I need to keep my o2 sensors reason I asked bc I'm swapping out the manifolds and putting on some headers and I can't seem to get that o2 out of the manifold.
What year VetteI think Bosch part number 13111 is the the one I bought when one of mine was bad. It has a longer wire so it doesn't need an extension. Its originally for the post cat o2 on a corvette. It was $70. But that's only if you can't get them out with an o2 socket and breaker bar.
