Freshening my 2000 XJ with 235k on it, I’m having trouble finding two good oem replacements that being a Bosch fuel pump and NTK oxygen sensors, anyone have links to where I can get them?

btw I have a three cat xj, two cats on manifold and one on the run of the exhaust

everything I’ve replaced so far has been the OEM specified or Mopar parts and I don’t want to skimp out this far in on cheap parts

Bosch's coming and going in availability has been a thing for years now.
The NTK's on the other hand seem to be a more recent N/A thing.
Last I knew all were available except for one out of the four that you need.
Only thing you can do is keep searching if you want those brands and hope something pops up.

I've had good luck with the Carter fuel pump if it's any consolation. I replaced it 2 years ago because the Bosch was hard to find, and the one that I could find was ridiculously expensive.

Rockauto has the mopar sensors for the 3 cat 2000 xj. They carry a denso fuel pump if your interested in that. It’s best to search periodically and buy the Bosch pump before you need it if that’s what you’re set on. I found one for my 99 over 2 years ago and haven’t needed it yet.

You can order NTK from advance auto.
