I have a brand new Evo (and possibly all other Mitsu or other cars w/4 wire O2s) for sale. I bought it because I had a code that led me to believe the sensor was bad. Well, the code cleared itself so I don't need it anymore. Just PM me with a resonable offer and you can buy it. Thanks!

 

is this the rear o2?

 

Honestly, If I was you I would hold onto it... O2 sensors go bad, you will probably need it eventually.

 

I am pretty sure it fits both doesn't it (maybe not) but I bought it for the rear, yes.

 

My O2 sensors are invincible.
