Complete Your Header Installation
BBK O2 Wire Harness Extenders are a must when installing full length headers on your 2018-2022 Mustang 5.0 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 BBK extensions and make all the connections look factory with no mess.
Easy Installation
OEM connectors and heat protective sleeves make installation a snap. Simply transfer your factory oxygen sensors to the new location in the collector and click these into place on the OEM harness.
Locator Tabs
Some connectors may require the small directional location tabs to be removed from the ends of the connectors to click into place.
Fits
2018-2022 Mustang GT (Front Only)
Professional installation is required.
