    O2 sensors need to be replace every 70,000 miles. They do wear out and give bad readings to the PCM which makes it adjust the fuel & timing thus effecting horsepower output. (Simple terms - O2 goes bad makes car run like poo!)


    Now when you get LT headers the front O2 bungs are sitting further back then on the stock setup. You have 2 good ways and 1 bad way to deal with this.

    Good options
    Option 1: Buy the extensions used these with no issues (I have these and have had no issues)
    Option 2: Buy the Bosh 13111 O2 sensors - they are for corvettes but still work on our cars, don't let the counter guy tell you different. These have a very long wire harness that will reach to the new O2 bung with no problems

    Bad Option
    Option 3: When you get the headers some include a extension kit that you can cut and splice in extensions for you current harness. This is bad and has caused more issues then solved.
