Walker 350-35120 Oxygen Sensor - Upstream, Upstream Left or Upstream Right
OE Replacement Oxygen Sensor for Select Vehicles
Walker OE Replacement Oxygen Sensor Part Number 350-35120 is a specific-fit, heated wide-band sensor engineered for direct replacement in select Porsche, Hyundai, Kia, Ford, Lincoln, and Saab applications. It is built to deliver the diagnostic feedback the ECU expects, helping maintain accurate air-fuel control and emissions monitoring.
Walker Products has focused on engine management and oxygen/air-fuel sensors since 1946, and the OE Replacement line is built around application-specific fitment and sensor position. For vehicles such as the Hyundai Veloster, Kia Rio, Ford F-150, and Porsche Cayenne, the correct upstream sensor location and connector style matter for proper system operation.
Key Features
- Part Number: 350-35120
- Heated wide-band oxygen sensor
- Specific fit for the listed vehicle applications
- Threaded mounting type with M18 - 1.5 thread size
- 5-wire design with oblong male connector
- Male spade terminal type
- 22 mm wrench size
- Overall length: 750.0
- Walker OE Replacement product line for application-matched sensor replacement
Detailed Description
Walker 350-35120 is an OE-style oxygen sensor designed for upstream positions where precise exhaust feedback is required. As a heated wide-band sensor, it supports fast operating temperature and stable signal output for the ECU. This matters on vehicles that rely on accurate air-fuel ratio data to manage drivability and emissions performance, including 2012-2015 Hyundai Veloster, 2012-2014 Hyundai Accent, 2012-2014 Kia Rio, 2012-2013 Kia Soul, 2009-2011 Ford Expedition, 2010 Ford F-150, 2009-2010 Lincoln Navigator, 2007-2009 Porsche 911, 2015-2018 Porsche Cayenne, and 2006-2009 Saab 9-3.
This part number 350-35120 is built for specific fitment and position, including upstream right and upstream left applications where listed. This part cross-references no additional part numbers in the provided data.
What This Sensor Helps Address
- Check engine light or malfunction indicator light related to oxygen sensor performance
- Poor engine running caused by incorrect air-fuel feedback
- Increased fuel consumption from inaccurate sensor readings
- Higher exhaust emissions from delayed or faulty upstream signal input
- Fault codes stored in the ECU tied to the affected sensor circuit
Installation Notes and Tips
Confirm the exact year, make, model, and sensor position before ordering. This sensor uses a threaded M18 - 1.5 mounting design, a 5-wire harness, and an oblong male connector with male spade terminals, so connector shape and wiring layout should match the original unit. Inspect the sensor wiring harness and connector for physical damage before installation, since damaged wiring can shorten sensor life and affect ECU feedback.
For fitment-specific ordering, verify the listed upstream location for your vehicle: Fits 2015-2018 Porsche Cayenne, Upstream Right; Fits 2012-2015 Hyundai Veloster, Upstream; Fits 2012-2014 Hyundai Accent, Upstream; Fits 2012-2014 Kia Rio, Upstream; Fits 2012-2013 Kia Soul, Upstream; Fits 2009-2011 Ford Expedition, Upstream Left; Fits 2011 Lincoln Navigator, Upstream Left; Fits 2011 Porsche 911, Upstream Right; Fits 2007-2009 Porsche 911, Upstream Right; Fits 2010 Ford F-150, Upstream Left; Fits 2009-2010 Lincoln Navigator, Upstream Left; Fits 2009 Ford F-150, Upstream Left; Fits 2006-2009 Saab 9-3, Upstream.
Quality Assurance
Walker Products manufactures engine management sensors as OE replacement parts for specific applications and positions, with ISO 9001/TS 16949 certified operations supporting product consistency and catalog accuracy.
