I need to know if evo8 o2 sensor fit evo9?

 

Go to Advance and buy the bosch universal O2.....less than 100 bucks......F! Mitsu and their prices........It should fit anyways to answer your question.....

 

Ask the dealer. They should know. Or maybe an Advance Auto Parts or Pep Boys may heve the PN for both cars. Just call and compare numbers. They should be the same.

 

dealer want $475...........there is no advance auto parts or pep boys where I'm at.
thanks anyway.

 

You're kidding me? Where do you live? bum Fuc Egypt?

Advance auto part is like herpes lol They're everywhere

yah order 1 or something thats a rediculous price the dealer told me 350 and i told them i would rather buy a 50 dollar one from advance and wire it myself

 

Maybe even AutoZone

 

the rear is not really that important as the front...you can just disable it..

 

Take a pic of the connector. I know what the Evo8's connector looks like. Hell, I even have an extra (I removed/disabled mine)

 

You can just disable it, but with the new emissions software thats being used it actually test to make sure the rear O2 sensors heater is working. If not you'll fail emissions regardless of if you have a CEL or not. To be honest just buy a universal 4 wire (I believe its 4 wire) oxygen sensor and wire it in. I hate wiring and this is so simple that I didn't mind doing it.

 

you can wire in a resister that tricks the ECU into thinking that the heater is work. also a heater element on the o2 isnt going to cause you to fail emissions, it shouldnt anyways becasue the o2 is still working correctly. it just isnt going to get itself up to temp as fast
