As @mlnnc stated... it’s a 50/50 chance new Bosch O2 sensors are bad for the Disco 2.
Any other Bosch part I will definitely buy for my Disco 2 but just not their O2 sensors.

I've installed Denso O2 sensors into my truck. No issues. Part # 234-4694 for upstream, part #234-4696 for downstream.

Aloha,
Thank you all for the recommendations. Picked up (2) sets from Amazon of the Denso sensors. Hope that this sorts out the issue.

Get a load of this; https://bobistheoilguy.com/forums/threads/ntk-vs-denso-o2s.166920/

Here was one interesting post: "From PCM tuning experience (on W-bodies) out of NTK, Denso, AC Delco, I like Denso the best. For whatever reason with the Denso fuel trims make up their mind and stick with it for a given rpm and throttle. If that makes any sense "

And another from the Jag forum:

Default

"There is a difference between the Denso and Bosch wideband. It's has to do with it's lambda voltage. If you see any type of problems with A/F trims or MPG, you need to find some Denso replacements."

Your results may vary.

I think I'll mess around and get 2 pair of Denso's.
