Might as well go with a 2 wire. The 2nd wire is just a more reliable ground. No more going through a rusty exhaust system to ground out.

Also, look for 'universal' o2 sensors for a cheaper alternative. Its the sensor with no connector so you have to cut off the connector from your old sensor and solder it up.
