Review & Install Video

Required For BBK Long Tube Headers. When installing a set of BBK long tube headers on your Coyote powered S550 Mustang the factory front oxygen sensor wire harnesses come up short and won't reach the upstream O2 sensors. That is why you will need a BBK Performance O2 Extension and Hardware Kit to bridge the gap allowing you to reconnect your sensors in an easy plug-n-play fashion.

Application. This BBK Performance O2 Extension and Hardware Kit is designed to extend the front (upstream) O2 sensor harnesses on the 2015 to 2017 GT Mustang models.

Please Note. O2 Sensors are not included with this Extension and Hardware Kit.

Fitment: 2015 2016 2017 Details

    2016 GT, BBK LTH Install

    The headers I received had extensions with them in the the hardware box. I don't know what year mustang they are for but they didn't fit any of my 02 connectors. These extensions did fit on my 02 connectors. The front 02 wire harnesses don't reach with the LTH, but these fix that problem. They leave a decent amount of excess wire hanging so you will need something like heavy duty zip ties to retain the excess.

    Works well

    After buying long tube headers from AM for my 15 gt and I ordered these being cautious to make sure I had the correct extensions for when I got around to doing the install, luckily for me I needed them cause the headers I got from bbl had the wrong bolts (11-14). I don't like that it only comes with one bag of bolts and only 5 of them in that bag when there's 8 bolts per header, but the connectors and quality seems nice and fitment is perfect. They're about 12" long. I placed a call to AM to see if they can include more bolts with the package considering it says "hardware kit".
