Land Rover Repair: 98 Disco Oxygen Sensor, ac delco, oxygen sensor

Question
Hi, I am trying to find a universal oxygen sensor for my 98 Disco series I.  I don't want to pay the high sticker price ($150+) for 4 new sensors when I replace my y-pipe and cats in the next few days.  I know the direct fit part # but do you know of a universal to exchange for any of the following sensors that are applicaple for my disco.
NKT#  25017
BOSCH# 13927
AC Delco# 2131498
Standard Motor Prod.# 56429

Any help would be great,

Answer
Hi Josh,

was there something wrong with the originals?  You don't think you can get them out from the old Y pipe?

Here is a website that I have used for my older Disco I
NTK (4 wire)only:

https://www.automedicsupply.com/catalog4.php?PHPSESSID=10d458a8a0c6401885b1acac4216f0c5#

It should take you right to the inventory page.  They sell for about $99.  They also have a "replaces" feature that lists the LR part numbers that the O2 sensor replaces.  Nice.

The other site I know of sells BOSCH and Walker O2's:
http://www.oxygen-sensor-warehouse.com/

I think Bosch sell for around $120.

Here's Bosch's O2 page:
http://www.boschusa.com/AutoParts/OxygenSensors

they even have a list of retailers.

The best price I know of are the NTK's, the best O2's are the BOSCH premiums.  

Best of luck,

JohnMc
