If the threads seem rusted then apply a rust cutter and let it sit for a while. Be sure to use never-seize on the threads of the new oxygen sensor if they are not already coated.

Lucky you  I was there as my indy struggled 30 minutes trying to remove the O2 sendor, standing under the raised car, with the right wrench of course.
