Here is a bit of the information that I have clipped and saved over the years. This shop/owner has been reported by many on several lists to be great!

I did all the research on O2 sensors awhile back when I replaced my
exhaust w/ an NRP system. I anticipated replacing the existing sensors.
However, I was able to salvage them and they work fine in the new
system. The NTK seems to be the best bet though for replacement, as it
has the proper wire connector on the end of it and they're the much less
expensive than the OE part. It's NTK part number 25016. That's for an
'89. I'd check www.ngk.com and click on the NTK O2 sensor link for the
configurator for your specific year.
'89 Range Rover
Oxygen Sensor Replacements-
Here is the context from rro:
The O2 sensors are available stock items.
Standard NTK part number that can be looked up in their cross reference
for my 1992 3.9 litre Range Rover;
Part Number #25016 (Made in Japan)
Made by NGK Spark Plugs (U.S.A), Inc.
It has the correct connector to plug directly into my 1992 3.9 litre
RRover. NO modifications required. $150 Canadian dollars all taxes in
and delivered to my door. That would put them at sub US$100. each
I installed both and they work great!

Excellent! I bought a pair of O2 sensors from Nathan recently, and they
were the duplicate of the Rover part. Prompt service, too. He buys 'em
direct from NTK Technical Ceramics (as does Rover). No need to
cut'n'solder or crimp on the old connector as with the Nissan

costly than the Nissan ones you have to fool with, as their prices
increased noit too long ago.
But this is what *really* bugs me about Rover. Nathan sells these sensors
for <$95 (the four-wire, OBDII-type is a few bucks more than the three wire
sensor). The local dealer charges $345 each. Okay, like a bottle of wine
in a restaurant is marked up 100% over retail, but 263% - at least??

Ahhh...that's the beauty of what Nathan sells: the *exact* same unit that
Rover uses. Same sensor, same wire length and same clip connector. (The
driver's side upper is a bloody bear to disconnect....) AFAIK, there are
only two kinds: a three wire used on pre-'96, OBD I vehicles, and the four
wire, heated titania sensor used on all OBD II vehicles since then - but
you need *four* of the bloody things.
BTW, Snap-On makes a 17mm deep well socket with a side cut-out that
facilitates removal and refitting of the sensors.

Good evening Listers. I offer the following hard knock lesson so that others who follow will not suffer my expensive fate.
A few months back the Check Engine light illuminated. The EFI code on my '90 County's LED read right O2 sensor. Nathan was out of stock, so I decided to try the Bosch Part #13021 as described on RangeRover.net. Plus, they were available at my local NAPA for $63 each. Installation required clipping off the plug of the Bosch and reusing the plug from the old sensor. Hooked it up, cleared the code, and all seemed well. Well, that is, for about 20 miles when the Check Engine light appeared again. Code showed left O2 sensor now. OK, fine. Same drill for the other side and life was again grand. For about 20 miles. Then the Check Engine light showed again and the fault code showed O2 sensor. Couldn't be. Cleared it, 15 miles later, Check Engine light, etc. The fault codes alternated from left to right sensor. Nathan got restocked, so I ordered a pair of the OEM NTK's at $89 each and installed them. At one point the Check Engine light reappeared and I almost went through the sunroof. I cleared it, however, and it has not reappeared for a month or so.
Bottom line, the Bosch 13021 sensors did not work in my '90 County, at least according to the EFI fault system. The OEM NTK's from Nathan have worked fine. Plus Nathan is pretty cool. My total costs per sensor as I tried to save a buck, though far less than the dealer cost, now approach those of the glossy catalog guys.
Anyone looking for a pair of Bosch 13021 O2 sensors? Hardly used, cheeeeeeap.

>I've heard "Nathan" mentioned before. Who is he?
Nathan Crabtree, purveyor of the *cheapest* OEM O2 sensors this side of the pond. He buys 'em a hundred at a time from NTK Technical Ceramics, the same supplier to Rover. Same terminals, etc., as Rovers. No fooling with splices as with using Nissan sensors (same sensor, different plug) or Bosch 'crossovers'. But these things deal with fractions of a volt, so a spurious splice will defeat your cost-cutting moves....
Pre-OBD II sensors are three wire, OBD-II are four wire, heated titania....
Last address I had for Nathan was firstname.lastname@example.org. he is now doing business under a catchy corporate name - which I have forgotten....
*----jeep may be famous, LAND-ROVER is legendary-----*
Allow me to remind anyone thinking of the inexpensive alternative O2 sensors instead of the OEM's of my unfortunate experience. I tried the Bosch #13021 (I think) as referenced on the RangeRover.net site when the Check Engine light came on and my LED readout indicated O2 sensors, first one then the other. They were $50 each and available locally. After less than 20 miles the light came back on after both sensors were replaced with the Bosch units. I reset the LED, checked connections and wiring, but still got the fault codes. I eventually got the OEM's from Nathan at Discount Rovers and haven't had a problem for many months. They were plug and play, while the Bosch required using the old connectors. Others must have had positive experiences with the Bosch and NGK units, but to do it over again, I'd just call Nathan.
For whatever it's worth. Have a great weekend all!
