4.2 xkr oxygen sensors

I have a 2004 XKR and have been looking to replace the oxygen sensors. Would anyone happen to have the part numbers for the 4.2l XKR. Thank you!

I used Denso Upstream DOX-0430 as recommended by RaceDiagnostics in post #8 of the below thread. They work excellent.

I just did one of my 03' XKR 4.2 downstreams with this one, and it fit and seems to have fixed the warning light!

Denso 234-4798

I’m torn between the two. They’re basically the same price and both say they are OEM Denso for the 2004 XKR, but they seem they are different. Which should I go with?
