Rear O2 Sensor Extension Harness



If your aftermarket downpipe moved your O2 sensor, you might find that your original wiring harness is coming up a little short. Your oxygen sensor wiring might also have failed due to age, heat, and chemicals. Lengthen or replace your crusty oxygen sensor wiring with one of iWire’s heat-and-oil-resistant O2 sensor extensions. They’re available in a 7 inch length for aftermarket downpipe applications or a 30 inch length for OEM replacement



Purchase the Rear O2 Extension Harness - $34.99




Purchase the Rear O2 Sensor Replacement Sub Harness - $49.99

Great question! We don't currently have all of the pieces needed to make this for the Front O2 sensor but we plan to start working on this due to demand.
