When you install a set of BBK Performance long tube exhaust headers on your muscle car or 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 - 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). All BBK Performance parts are backed by a 1-YEAR manufacturer’s warranty from the original date of purchase. An optional extended warranty is also available - giving you an additional 2 or 3 years from original date of purchase. Costs for the extended warranty option can be viewed when the item is added to your cart. The manufacturer’s warranty is based on normal use and installation of each product.. 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 on the OEM harness..
