I am trying to find a wide band O2 sensor to build the DIY-WB project. How does one identify a wide band O2 sensor? Are there different ones other than the NTK 5-wire O2 sensor identified for the DIY-WB project? I've been to several auto parts stores and no one carries the NTK. They have several that supposedly cross to a 95 honda civic vtec. Bosch 13246($190 not in stock), Bosch universal 15734($70) which is 4 wire but looks like it has an external O2 inlet... what's this all about? Are all 5 wire sensors wide band?
Thanks,
Tim
