It is engineered to deliver the diagnostic feedback the ECU expects, helping maintain proper air-fuel control on upstream and downstream positions.\u003c\/p\u003e\u003cp\u003eWalker Products Aftermarket focuses on engine management and oxygen\/air-fuel sensors for exact application fitment. The 350-34372 follows that approach with a threaded, 4-wire heated design and a radiused polygon male connector for the listed vehicles.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHeated oxygen sensor for ECU feedback and emissions control\u003c\/li\u003e\n\u003cli\u003eSpecific-fit design for the listed Hyundai Genesis, Hyundai Equus, Kia Borrego, and Kia K900 applications\u003c\/li\u003e\n\u003cli\u003eThreaded mounting type with 18.0 mm thread diameter\u003c\/li\u003e\n\u003cli\u003e4-wire configuration with 22-gauge wiring\u003c\/li\u003e\n\u003cli\u003eWiring harness length: 13.31 in.; overall length: 16.85 in.\u003c\/li\u003e\n\u003cli\u003eRadiused polygon connector shape with male terminal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDetailed Description\u003c\/h2\u003e\u003cp\u003eThe Walker Products 350-34372 oxygen sensor is designed for direct replacement in select 2009-2017 Hyundai and Kia vehicles, including upstream right, upstream left, downstream right, and downstream left positions where listed. It is intended to restore accurate exhaust-gas feedback so the ECU can manage fuel delivery and emissions monitoring correctly. This part number is a practical choice when replacing a failed sensor on a Hyundai Genesis, Hyundai Equus, Kia Borrego, or Kia K900.\u003c\/p\u003e\u003cp\u003eAs part of the Walker Products Aftermarket line, this sensor is built around application-specific fitment rather than a universal design. The heated sensor layout, connector style, and threaded mounting dimensions are matched to the listed vehicle positions for straightforward service replacement. Part number 350-34372 is also referenced as Walker 350-34372 in catalog searches.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCheck engine light related to oxygen sensor performance\u003c\/li\u003e\n\u003cli\u003ePoor fuel economy caused by incorrect air-fuel feedback\u003c\/li\u003e\n\u003cli\u003eRough engine operation from inaccurate exhaust readings\u003c\/li\u003e\n\u003cli\u003eElevated exhaust emissions from a failing sensor\u003c\/li\u003e\n\u003cli\u003eStored ECU fault codes tied to the affected sensor circuit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eBefore installation, inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion. Confirm the vehicle position carefully, since fitment varies by upstream and downstream location as well as left and right side on the listed Hyundai and Kia models. Use the correct threaded mounting procedure for the 18.0 mm sensor body and verify the connector orientation before final routing.\u003c\/p\u003e\u003cp\u003eFits 2009-2016 Hyundai Genesis, upstream right, upstream left, downstream right, and downstream left; fits 2011-2014 Hyundai Equus, upstream right, upstream left, downstream right, and downstream left; fits 2015-2016 Hyundai Equus, upstream right; fits 2009-2010 Kia Borrego, upstream right, upstream left, downstream right, and downstream left; fits 2010-2011 Kia Borrego, upstream right; fits 2015-2017 Kia K900, upstream right.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eWalker Products has manufactured engine management and oxygen\/air-fuel sensors since 1946 and operates as an Automotive ISO9001\/TS 16949 certified company.
