Built with OEM-grade components and MIL-spec wiring, this kit eliminates the need to cut, splice, or modify your factory O2 harness during a long tube header install.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eWhen you install long tube headers on a VQ35DE, the primary O2 sensor location moves significantly further from the cylinder head than the factory exhaust manifold position. The factory O2 sensor harness isn't long enough to reach the new sensor location, which forces most installs to cut and splice the existing harness. Splicing O2 sensor wiring is a common source of long-term electrical issues, ECU codes, and lean conditions. This extension kit gives you the additional length you need without ever touching the factory harness.\u003c\/p\u003e\n\n\u003ch3\u003eConstruction\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOEM housings, locks, wire seals, and terminals\u003c\/li\u003e\n\u003cli\u003eMIL Spec M22759\/32 Tefzel wire\u003c\/li\u003e\n\u003cli\u003eDirect plug-and-play installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eThis extension only fits vehicles with the heated O2 sensors that use BLUE and GREEN connectors:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e2002-2004 Nissan 350Z (VQ35DE)\u003c\/li\u003e\n\u003cli\u003e2003-2005 Infiniti G35 (VQ35DE)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eVerify your O2 sensor connector colors before ordering.
