04 Oxygen Sensor Question

  1. Hi all,

    Having a little problem. I am replacing the stock H pipe with a Magnaflow Catted X Pipe. When I was taking out two of the oxygen sensors, they were VERY hard to get out. When the factory installed them, they ended up cross threading the O2 sensors. two came out very nice, but the other two are toast. Needless to say two O2 sensors and 2 bungs are completely unusable.

    Ok, now that the preliminaries are out of the way, I have been searching for the O2 sensors online and am a little confused. I need a front (before cat) sensor and a rear (After cat) sensors.

    The rears are Ford part number: XR3F-9G444-A2A
    The fronts are Ford part number: XC2F-9F472-A1A

    All the parts stores list the Bosch 15716 as the replacement for both front and rear. Is this correct? The sensors look different.

    Any help would be appreciated.


  2. All the sensors are the same...for cheap replacements get them from http://www.oxygensensors.com ....you can get 2 of them shipped for the same price as one Bosch from Autozone (Around $40 each with free shipping)...I ordered replacement front O2 sensors from there and haven't had a problem with them...had them in for about 20k miles...
