i just ordered an O2 sensor for my 95 318is from the local autozone. looking at the picture, i think that it only has two wires, whilst mine has four. will i be able to use the two-wire sensor, or will i have to return it for a four-wire one?

The four wire ones have a pre-heater in them. If you use the two-wire one instead, you will probably trigger errors by the computer as it will think the heater circuit is dead.
