What narrowband o2 Sensor

Post by ReaperCustoms »

Hey guys, just wondering what is the best narrowband o2 sensor to use? Car will be tuned on the dyno with a wideband but just want to use the narrow for closed loop cruise stoic.

is it always better to use a 4-wire sensor or is there no real benefit over a 3-wire?

The last vehicle I did I used a 4-wire sensor but when I went to my local parts store and just asked for a 4-wire sensor they said they didnt have a "universal" sensor and I had to tell them a make/model of vehicle so I could find a part number. Cannot remember the model but it was a Toyota and considerably more expensive then a 2-3 wire sensor...

So just wondering if anyone has any part numbers for suitible sensors or what makes/models of cars they are on... or maybe a website that sells suitable sensors?

Thanks
