    Plug and Play. When replacing the factory manifolds and Mid Pipe with a set of long tube headers and a shorty Mid Pipe on your 5.0L Mustang, you may notice the factory oxygen sensor wire harness comes up short when trying to hook up the front (upsteam) o2 sensors. An easy solution to fix this issue is picking up a pair of BBK Performance O2 Wire Harness Extension Kit. BBK designed these 12 inch long extension kit with OEM factory connectors to make it a simple plug and play install when you need to reconnect your sensors.

    This set of two 12 inch BBK Performance O2 Sensor Extensions are designed to extend the front(upstream) O2 sensor harnesses on the 2011 to 2014 GT Mustangs equipped with the 4 valve 5.0 coyote engine.

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

            Really great product. The quality was nice and plugged into the factory harness with no issues. Installation was super easy. Just plug in and your done.

            BBK O2 wire harness

            They fit good with speed daddy headers. The plug connectors are hard to get to so get a wire hanger to grab it if you have big hands.

            Bang for buck

            Fit on spot, but wouldn't click into other end, used zip tie to hold together but no issues.

            Perfect fit

            Plug and play easy install hardest part was disconnecting the o2 sensor without breaking clips. Snap in the extension into factory harness and o2 sensor and your ready to go. Length was perfect for my longtube headers

            Great quality harness

            Looks like a factory harness , worked great for my long tube header install. Not the cheapest part in the world, but definitely great quality.
