2018-2020 Mustang o2 Extension - PAIR

Wire Harness Extenders are a must when installing full length headers on your 2018-2020 Mustang, due to the fact that the O2 sensor locations are relocated on full length headers. So rather than cutting into your factory wire harness to make the connections reach, simply plug in a set of 2M extensions and make all the connections look factory with no mess.
