Thanks for quick reply. I will go with Bosch, in Australia they come as per the attached photo. Which one would be the one I need? Post or pre catalyctic converter? ThanksYes. You can swap sensors to test. They are interchangeable if the wire length allows it.. Bank 1 sensor 1 and bank 2 sensor 1 I mean.
And be careful when buying.. B1 s1 and b1 s2 are different types of sensors.
