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

I replaced one of them when I changed out the cat on my truck. I wanted to do all but couldn't at the time. All 4 will be the same part number like you have listed.

Thanks! I take it that it worked fine and didn't throw any codes?

Works just fine. No codes at all.
