When you install a set of BBK Performance long tube exhaust headers on your 2019 and newer RAM 1500 truck, the O2 sensor locations are relocated on the BBK header and mid pipe. The factory O2 sensor wire connectors will not be long enough to connect to the sensors any longer.. These extension harnesses extend the length needed and allow them to now connect easily to the mid pipe - All our extension harnesses feature OEM Factory connectors to allow simple plug in installation to the factory wire harness so that the relocation is super simple and does not require any splicing of the factory harness at all. (Sold in Pairs)

• BBK Performance oxygen sensor extensions feature OEM Factory connectors on the end of the wiring to allow simple plug in installation to the factory wire harness. Includes a heat protective sleeve for maximum protection.
