Does this sound right? Or did the parts guy look up the wrong part? I've been throwing a P0420 code, and am only getting about 20mpg/hwy, so I'm pretty sure it's an o2 sensor. I was going to replace the sensor in the cat first, but now that it looks like it might cost $300....

 

Yes price is correct. I have good low mile one if you are interested. PM me.

 

If you want to replace an O2 sensor just go and buy a Universal Bosch sensor that you wire in. It's around $50 and works perfect.

Stealership

 

++1 autozone or any parts store should sell them also. i stripped my threads out on mine when replacing my 02 housing and the stealership told me 364.XX i had to ask them twice. but then i just went with one of these!!

Has anyone gotten an o2 sensor from this site? They list both the OE pre- and in-cat sensors. Do they come with the appropriate OE plugs as well? Or will I need to hard-wire these in?

 

that's the price they quoted me too but you can find them cheaper

 

How do you match up the wires if you purchase a universal O2 sensor? The rear O2 has four wires ( two black, one white, and one blue). Are the two black wires ground and doesn't matter if they are switched?

 

Dont pay 300$ are you crazy... their way cheaper then that

 

Yes ive gotten one here... EVO specific plugs right in

 

I have checked both sites and only can come up with either the same o2 sensors the stealership sells and oxygensensors.com doesnt even have a mitsu section

 

yes they do.. heres for my 05 MR

Its stops at 05. They dont have any listing for mitsubishis in 06.
