Complete Your Header Installation
BBK O2 Extensions are required when installing full length headers on your 1986-2010 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 BBK extensions and make all the connections look factory with no mess.
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 between the OEM harness and O2 sensors.
Because factory connectors vary, some connectors may require the small directional location tabs to be removed from the ends of the connectors to click into place. The tabs can be easily cut or filed off.
