bosch 15664 o2 sensors
Has anyone replaced their o2 sensors with the Bosch 15664 ones? Rockauto listed them as upstream as well as down stream. Can anyone confirm that if you have replaced them? I am going to replace my cats and figured I might as well replace the o2 sensors while I'm under there.. they are $40 each which is reasonable imo..
Thanks in advance
