in miami
yes they are in miami...i will look up the place for you....give me a day.... I got bosch for $30.00 a piece and universals for $19.95.. Both are 4 wire heated 02 sensors. You need 4 wire for front and back. You need to splice in your old plugs but it takes 10 minutes to do for each one. I cant see paying $20.00 for plugs...thats rape... and i bend over enough for this POS....
DO NOT use universal O2's, they will not work.
The ECU needs to read the correct OHMs from the O2's and splicing the wires will mess that up.
I used a universal on my wifes car, threw codes left and right and she ran rich, finally replaced it with a correct one and all is well once again.
You do not need to replace the downstream O2's, all they do is tell the ECU that the cats are working.
So unless you are getting codes for the rears leave them alone.
www.amazon.com has the best prices on O2's.

whats wrong with the bosch? they are direct replacment just without plugs...they are four wire.....i never had a code on my 95 Rr 4.0 with them... i solder and shrink tube all my connections...i cant see what the difference would be....i know my disco is a POS but your telling me it will throw codes?

Bought it from Advance Auto for $95, used it for a year, it was crap.
A new one at Advance was $200? or so.
Bought one for her car off of e-bay for $65.
Works great.
Go to Amazon, in the search box enter what you are looking for..."Land Rover oxygen sensor" then find the ones you are looking for.
ok, after reading all the posts on this thread I still have no idea what this thread is about other than a cheap source of O2 sensors- btw what is the cheapest source of quality, usable O2 sensors for our disco II's?!
