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, all you need to do is plug in a set of BBK O2 extensions. Not only is it simpler, it allows you to make all the connections look factory with no mess.
BBK O2 extensions use 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.
