Complete Your Header Installation
This BBK Long Tube Header Hardware Kit is required when installing full length headers due to the fact that the O2 sensor locations are relocated on full length headers and there are some different bolts required that are specific to the 2015+ model.
The included O2 sensor extensions feature OEM 6-pin 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.
