Cheap O2 Sensors from Flying Circus

I have 2 sensors that meet your spec.
They are 3 wire Bosch 13913 (0 258 003 913) have 18mm threads and a 12v heater
in them.
We sell them to Jaguar XJ40 (XJ6 from 90-94) owners
The 3 wire lead is 6" long and ends in a Ford plug. Our price is $42 dollars
US each and I am researching a cost effective way of shipping them to NZ
faster than ground.
Are you sure you cannot find them locally with the above numbers?
I will e-mail when I have shipping times and costs. Please confirm if you
want me to ship and, yes, we do take Visa/Mastercard

Best wishes
Alan Briggs
