Re: zc o2 sensor question??
Get one that matches the ECU that you're using, because narrowband O2 sensors often have heater elements in them which are controlled by the ECU. Don't assume that you need a single wire O2 sensor just because that's what your original harness has on it, make sure and research it for the ECU first.
