I'm nearly 100% certain that the OEM O2 wideband sensors are actually Bosch. If you look at the images on RockAuto, especially the sensor body and the heat resistant wire wrap, you can see that the Bosch part and the Motorcraft part match 1:1, that can not be said for the NTK or Denso options. So, if you need OEM spec, I would suggest Motorcraft or Bosch.
