    O2 Sensor installed in exhaust manifold problem..

    I just installed the O2 sensor in my manifold as the picture...BUT the sensor its 1" deep inside the manifold and the hole i have to drill its more than 1" deep.. so the sensor its like 3mm inside the manifold and the mechanic told i would not have a good reading with this...
    What i should do or its OK...
    PD: If you saw it from the exhaust hole, you will only see the drill hole and inside of this you could see only the a little part of the 02 sensor...
    please help me...
    many thanks

    Many people run the 02 sensor in that location... including myself. Your readings will be fine in that location even though the tip of the 02 does not protrude into the manifold. Speedskixp tested sensor readings in that location vs in the J-pipe where it does protrude, and got near identical numbers. Maybe he'll chime in to confirm this.

    Yep, as the others have commented.
    I even run mine with a heat sink which even pulls the sensor further away and I am having excellent readings and my sensor is lasting.

    Is that black magic manifold an improvement over the stock unit?
