What do you want to test? My understanding is that the upstream sensor is a wide band sensor, and the down stream is a narrrow band sensor. So, you cannot run the same sensor in both locations.

If you are strictly asking about the “brand” of sensor, doesn’t matter either, as long as it’s designed for the location being installed.

Thanks,

I put in an o2 extensions on my downstream with my NTK sensor as the Bosch doesnt like extensions.
