I need to replace the O2 sensors on my '93 Range Rover (getting a 45 code on the OBD1 display), but the Atlantic British parts are over $100 each (need 2), OR an NGK equivalent is only $29 each. The NGK has a bare 3-wire harness whereas the AB parts have an OEM plug. The shop that does the work will likely have to spice the left-side new part into the existing old-part harness, because as far as I can tell, the left-side plug is un-reachable unless you remove the entire intake assembly.
But anyway, I was harshed on my Range Rover forum for considering a non-British-source part for the "miniscule" difference in price, but I'm thinking if the interchange P/N's are compatible, and since the shop will have to cut the nice AB harness to splice it into the existing plug anyway, will the engine really care which pair of O2 sensors are installed? How do sensors operate anyway, and could the specs on the British part be different than on the NGK part such that the engine will suffer?
I've always had good luck with NGK products.

I know little about O2 sensors (all my bikes don't have them or they're disabled) so I didn't file the details away, but there has been recent discussions on V11Lemans on the benefits of replacing bikes equipped with oem MG O2 sensors,with a generic brand,possibly Bosch?
Iirc these O2 sensors were not only cheaper,but their quicker reaction time & improved efficiency communicating with the ECU,resulted in much improved engine performance.
How your Rover & sensors,NGK etc are set up & would run,idk.
fwiw

Being three wire usually means its a heated sensor. No idea if time it takes to get up to operating temp could trigger an error. Being the, ahem, frugal type I would take a chance and get the bargain price model.

Thanks for the replies. Since posting, I've talked to others and the consensus is NGK products are reliable (my experience, too), and since the Interchange #'s seem to indicate compatibility, that's good enought for me.

No idea who makes the rover part, but most european sensors seem to be made but NGK or Bosch anyways. I would do it.. more so beacuse you need to splice it in anyway, so ne need for the right connector.

very specific the heater has different resistance. connector wires in different cavity the only ones that may work would be a early single wire
