Motorcraft DY1401 O2 Sensors on a V12V

Hello, does anyone know if you can use the Ford Motorcraft DY1401 O2 sensors on a 2011 V12 Vantage? If not, does anyone know what the equivalent Ford/Motorcraft part number is for replacement of O2 sensors?

I'm getting a P0152 02 Sensor Circuit High Voltage (Bank 2 Sensor 1) code and suspect its a bad sensor.

I would compare on Scuderia Car Parts or Eurospares your Vantage to the same year of a DB9 (most any year really).
If the oem numbers match, then yes.
I asked Steve on Aston1936 how its been going after he replaced all 8 with the DY-1401's and his reply was "Great"

That's a great idea. Just checked, yep same part number for both V12V and DB9. Though the upstream and downstream are different part numbers (1R12-39-10174 & 1R12-39-10175). Is there an equivalent Motocraft part numbers for the two different ones or will DY-1401 work for both? I assume the connector needs to be modified?

I thought the DY-1401's would work for all 8

I had tried an experiment and installed Delphi ES20104 as a pair on the secondary bank upstream O2 sensors, they started throwing codes after a few months.
I just replaced the Delphi's with a pair of the DY-1401, no issues with cable length or connector fit.
It's only been 3 days, so i'm hoping i can report "They are great" after a year or so.

From my research I found Ford Motorcraft might be DY-1042 as an upstream sensor, but after Steve's response i went with the DY-1401's

You are correct, yes. At least for our Rapide.
