I can't find the 17041 anywhere

 

The OEM part numbers directly align with Denso part numbers, not Bosch, and you can buy Denso sensors with the correct part numbers from multiple sources at a fraction of the dealer prices. If you can't find a particular equivalent Bosch sensor in-stock, perhaps you should just go with Denso.

 

Thank you, I didn't know that. Looks like these may be it. The upstream isn't listed as an o2 sensor but I'm sure it's still the correct part.
