Eliminate the cut-and-splice step when installing long-tube headers. these plug into your factory O2 sensor connectors and extend the wires far enough to reach the long-tube primary sensor positions.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eLong-tube headers move the primary O2 sensor location further from the factory wiring harness than your factory wires can reach. The traditional fix is to cut and splice extension wire into the harness, which is functional but messy and not particularly reliable. These pre-made extensions plug directly into the factory connector on one end and your O2 sensor on the other, completing the circuit without any wire cutting. Cleaner install, no soldering, and easy to remove if you go back to factory headers later.\u003c\/p\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eMost 2011+ 370Z and G37 models with the 4-wire primary O2 sensor connector.\u003c\/strong\u003e \u003cstrong\u003eInspect your factory O2 sensor connector before ordering\u003c\/strong\u003e to confirm you have the matching plug type.
