they measure oxygen passing thru the system at inlet and outlet ends. u need 2 for inlet and 2 outlet, but depends on which ones are faulty (e.g cyl 1-3, 4-6). Bosch ones cost a fortune from the dealership but the same ones can be bought from GSF for about 45ish each. u can get cheap universal ones (4 wires ones) and DIY it yourself, usin the existing couplers etc., as they are easy to get to if u have thin hands
