Part number for the universal 4 wire o2 sensors that fits our cars?

[Frostedbutts]

Anyone know the 4 wire, M18 x 1.5 equivalents for universal oxygen sensors that fit our cars? The type that come without the plug, and you wire them into your existing harness.

So far I think I have found Denso 234-4013 as a fitting model, but I'm not sure. I'll update this thread as a reference point for any fitting #s if anyone can 100% confirm.

Working Sensors:

NGK NTK-124

What model car do you have? 1st gen? 2nd gen? TT? NA? I believe they are the same but Mitsubishi ASA lists a differnt part between 1st and 2nd gen TTs. Part number MD165083 is the 1st gen part and RockAuto have this part listed.

Found them by searching the site for the mit part number. Don't know about the connector though....

Hmmm actually those are the part numbers for the JDM cars and they only have 1 O2 sensor. IIRC FED SPEC has 2 and CAL SPEC have 4. Below are the part numbers taken from MIT ASA USDM

FRONT O2 =
MD305147 [for 95-97 model]
MD343989 [for 97-99 model]

REAR O2 =
MD305149 [for 95-97 model]
MD343988 [for 97-99 model]

FRONT PRE CAT O2 =
MD164422 [for 90-92 model]
MD186991 [for 92-99 model]

REAR PRE CAT O2 =
MD164423 [for 90-92 model]
MD186992 [for 92-99 model]

1st gen TT.

I've found the part numbers and tried to cross reference them to their universal equivalents, but RockAuto wasn't giving me what I was looking for. There's a slew of 4 wire Denso/Bosch/etc Universal O2 sensors on ebay for $25-35~ bucks, and I'm looking for which ones are the correct thread pitch (M18 x 1.5) for the 3/S. There were a couple threads on 3si about it, but the posted ebay links expire after 6 months.

For future reference

NTK-124 universal sensor fits the 3S. All you need to do is clip your old harness and wire it in to the new sensor, I'll post the wiring diagram and some pictures when I do it.
