the reason i dont go 4 wire is that my ECU doest control pre-heat, meaning i would have to build a pre-heat set-up to run it. i know the pre-heated (4 wire) ones are spose to be more accurate. maybe next time i will try one.

afaik, the heated sensors have a heater that is self regulating, ie it draws a constant current of 1 or 2 amps, the wide banmd sensors have a diffusion cell circuit and require a driver circuit, but i'm pretty sure NB 4 wires are fine just to hook up and go..
anyone else know?
