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)

• OEM connectors and heat protective sleeves are used to make installation a snap. Simply transfer your factory oxygen sensors to the new O2 sensor location in the collectors and click these into place on the OEM harness.
