Which Lambda?

  1. #1
    MK1 VTR
    Single Plug
    Blacktop.

    Am putting it back on the road and so am after some components the only thing I'm not sure on is which Lambda sensor I require.

    Looked on GSF website and found 2;
    UNIVERSAL 3 WIRE SENSOR
    4 WIRE UNIVERSAL >96

    Which one do I require?

    it'll be a 4 plug connector

    its a 4 wire and the universal ones are a bit hit and miss. I would try pickup a 2nd hand one thats genuine.
