    • Great for Modified Exhaust Systems

    Plug And Play. When modifying your Mustangs exhaust system, the stock rear oxygen sensor wire harnesses usually come up short and won't reach the downstream O2 sensors, but a set of 12" BBK Performance rear harness extenders will help bridge the gap allowing you to reconnect your sensors in an easy plug-n-play fashion.

    Application. This set of two 12" BBK Performance O2 Sensor Extensions are designed to extend the rear (downstream) O2 sensor harnesses on the 2011 to 2014 GT and V6 Mustangs, does not fit Shelby GT500 models.

    Please Note. O2 Sensors are not included with these extensions.

    Fitment: 2011 2012 2013 2014 Details

        1 Top Rated Question

        Will those extensions clear the check engine light appearing because of the O2 sensors? Or do I have to tune it anyways?

        • Hi, This BBK O2 Sensor Extension Kit will not clear a check engine light, You will still need to get a Tune/Tuner from BAMA to eliminate the light.

            O2 extentions

            Does what it's supposed to do. Seems high quality. Very well insulated to protect from exhaust heat. Would recommend to anyone who needs these for long tube headers or just to extend their o2 sensor reach.

            Perfect fit

            I have long tube headers with a catless x pipe and the rear o2s wouldn't reach. These gave it just the right length with no extra wires hanging.

            Super simple, just plug and go.

            First off, let me state that the only reason I needed these was because when I ordered the 2011 V6 BBK catted xpipe that one extension was missing. Needless to say, I was not happy with who ever is responsible for the QA on packaging. Since it was the weekend I was forced to plug the hole while the sensors were shipped. AM handled me very well, doing the fastest shipping possible and charging me nothing, as I would expect when the customer isn't at fault. The extensions really are plug and go. I had no issues with fitment and haven't had any problems. The build quality is at least up to what the stand OEM cords are, if not slightly better. If you need the extensions because you don't want to splice and solder etc., then this is a great product.
