what does it do and where does it go?? between wat parts???

 

Are you talking about the o2 sensors?

 

The o2 housing is located between the hot side of the turbo and the downpipe. Replacing the housing alone will not yield significant gains... but can add 5-7hp when combined with a full 3 inch turboback.

 

can someone show mee a pic of it.. when its connected to the other parts.. i've seen one jsut by it self.. but can't picture where it goes... also... the waste gate connects to it rite??? reason i'm asking is cuz i'm putting together parts for my future evo =D and i wanna try to put a different waste gate on it also... and u know they have different flanges and stuff..

 

I just bought an o2 Housing, How difficult is the install on this.. anyone know what size wrench, and whats required to put the bastard in..
