I'm looking at changing to using heated O2 sensors. We currently are using the stock single wire sensors, but as they are so far away from the nearest cylinder (custom headers) they don't seem to be working too well.
So I'm told heated sensors are the way to go, but our ECU doesn't have the heater plugs - can I just wire 12v to the heater wires on the sensors when the key is on? I've read that you can do just that, and also read that the sensors cook themselves if the ECU is not controlling the heaters - which is correct?
And if I can just wire 12v to the heaters, what sensors should I be buying? Are all narrowband O2's created equal?
I see RockAuto has the denso 4 wire sensors for a 94 LS400 for about USD$56 - would these work?
Any help would be great, thanks
