Does anyone know if I can source the stock narrowband O2 sensor from someone other than Mitsubishi? IIRC the Mitsu sensor is somewhat overpriced...

I run leaded race gas 24/7 and wanted a spare O2 "just in case". I made a post in the wanted forum and got a like new used O2 from a fellow EVO owner.

I paid $75 shipped. I recommend doing the same.

 

you can pick up a generic bosch 02 sensor from any local auto parts store. The only difference is the plug won't match, but that's an easy fix. I forget what I paid for mine, it was cheap though and works perfectly.

 

Will any Bosch work, or is there a specific part number that I need? I'd rather not go the route of a used one ... I just don't trust used O2 sensors.

If you are looking for great plug n' play o2 sensors you can get them at http://oxygengeek.com/. The SNG sensors they sell are great and you cant beat the price with the connector! There is no reason to pay $230+ for a Mitsubishi labeled Denso o2 sensor.


The Front o2 sensor (SN4-126) is $48.67

The Rear o2 sensor (SN4-60) is $63.94

These guys were great and I got a replacement 2 days after I ordered.

I still have the box mine came in at the house if you don't mind waiting till this evening for the part number.

 

I've got a stock one I pulled off my car at 22K. I thought it was a bad O2 sensor, but it was a dirty MAF probe. You want it? Name your shipped price and PM me.

 

I need an o2 sensor. Is the one you have for the front or the rear?

 

If you run race gas, just unplug your rear o2 sensor & dont worry about it getting fouled out

 

The only difference between the sensor is the length of wiring and the type of connector. I would pick up any generic sensor, and splice your factory connector onto the replacement sensor

 

here's a link to the exact bosch unit i've been using for over a year. I have a wideband also, and I idle and cruise at 14.7:1, so I know it's working.

$35 and change.... you can't beat it. 4 wires to hook up, and there are instructions on which colors tie into which wires on the factory harness.

It's Bosch part number 15730.

thanks guys.

CrackerJackToy, I'm looking to replace the front O2 sensor, not the rear O2 sensor. Can't just unplug the front one, unfortunately.
