Sold as a set of 2 covering both the left and right bank sensor positions on the VQ35DE V6. NTK is the world's largest manufacturer of original equipment oxygen sensors, supplying the sensor technology used in many Nissan vehicles as original equipment. Each sensor is individually tested during manufacture and supplied with a direct-fit factory-matched connector.\u003c\/p\u003e\n\u003cdiv class=\"wl-pull\"\u003eThe VQ35DE has four oxygen sensors in total two upstream (pre-cat, one per bank) and two downstream (post-cat, one per bank). The pre-cat sensors are the primary fuel control sensors, monitoring exhaust oxygen content directly after the exhaust manifold and sending closed-loop feedback to the ECU to maintain the correct air to fuel ratio. A faulty pre-cat sensor has a direct and immediate effect on fuel economy, drivability, and emissions on the 350Z.\u003c\/div\u003e\n\u003cdiv class=\"wl-diagnostic\"\u003e\n\u003cp\u003e\u003cstrong\u003eCommon symptoms of a faulty pre-cat oxygen sensor:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e• Check engine light with fault codes P0130, P0131, P0132, P0133, P0134, P0150 or similar upstream O2 codes\u003c\/p\u003e\n\u003cp\u003e• Increased fuel consumption\u003c\/p\u003e\n\u003cp\u003e• Rough idle or hesitation under acceleration\u003c\/p\u003e\n\u003cp\u003e• Reduced engine performance\u003c\/p\u003e\n\u003cp\u003e• Failed emissions test\u003c\/p\u003e\n\u003c\/div\u003e\n\u003chr class=\"wl-divider\"\u003e\n\u003ch2\u003eProduct specifications\u003c\/h2\u003e\n\u003ctable class=\"wl-table\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart number\u003c\/td\u003e\n\u003ctd\u003eOZA817-EE1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eNTK (NGK Group)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eZirconia oxygen sensor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePosition\u003c\/td\u003e\n\u003ctd\u003ePre-catalytic converter (upstream) · Both banks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eUp to November 2004 build date\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector\u003c\/td\u003e\n\u003ctd\u003eDirect-fit factory-matched\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSold as\u003c\/td\u003e\n\u003ctd\u003e2 sensors per pack (LH and RH bank)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003chr class=\"wl-divider\"\u003e\n\u003ch2\u003eWhy NTK\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eNTK is the world's largest supplier and manufacturer of original equipment oxygen sensors, with ceramic sensor expertise derived from the same technology used in OEM supply to Nissan\u003c\/li\u003e\n\u003cli\u003eSuperior dual-coated platinum interface and thinner ceramic element produces faster light-off and response times with improved durability compared to standard replacement sensors\u003c\/li\u003e\n\u003cli\u003eIndividually tested during manufacture to guarantee quality and reliability that meets or exceeds OEM specifications\u003c\/li\u003e\n\u003cli\u003eSupplied with a direct-fit factory-matched connector for plug and play installation with no wiring modification required\u003c\/li\u003e\n\u003cli\u003eDesigned to maintain optimal fuel efficiency, emissions performance, and closed-loop fuel control on the VQ35DE\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr class=\"wl-divider\"\u003e\n\u003ch2\u003eInstallation\u003c\/h2\u003e\n\u003cdiv class=\"wl-install\"\u003e\n\u003cdiv class=\"wl-install-box\"\u003e\n\u003cp class=\"wl-install-label\"\u003eDifficulty\u003c\/p\u003e\n\u003cp class=\"wl-install-val\"\u003eIntermediate\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"wl-install-box\"\u003e\n\u003cp class=\"wl-install-label\"\u003ePosition\u003c\/p\u003e\n\u003cp class=\"wl-install-val\"\u003ePre-cat · Both banks\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"wl-install-box\"\u003e\n\u003cp class=\"wl-install-label\"\u003eTools required\u003c\/p\u003e\n\u003cp class=\"wl-install-val\"\u003eO2 sensor socket\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"wl-install-box\"\u003e\n\u003cp class=\"wl-install-label\"\u003eWiring required\u003c\/p\u003e\n\u003cp class=\"wl-install-val\"\u003eNone\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003chr class=\"wl-divider\"\u003e\n\u003ch2\u003eFitment\u003c\/h2\u003e\n\u003cdiv class=\"wl-fitment\"\u003e\n\u003cp\u003eNissan 350Z Z33 DE · 2003 to November 2004 (VQ35DE · 3.5L V6) · Pre-cat upstream · Both banks · 2 sensors included\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp style=\"font-size: 0.88em; color: #6b7280; margin-top: 6px;\"\u003eSuits VQ35DE 350Z built up to November 2004 only. 350Z DE models built from November 2004 onwards use a different pre-cat sensor.
