Chaps, does any body know a part number for the upstream / downstream sensors - from the factory they are charging over £200 per sensor . But I think Bosch make them . They seems to be 5 wire , but they have about 2 feet of cable on them ! Answers on a postcard please!
If you get up close with your mobile & good lighting you may be able to get a shot of the part nr on the barrel of the sensor & as Heinz suggests NGK used to have a cross ref look-up in line
