These BBK O2 Wire Harness Extenders are a must when installing full
length headers 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. Some
connectors may require the small directional location tabs to be
removed from the ends of the connectors to click into place.
