Walker 350-34611 Oxygen Sensor - Downstream Left

Walker 350-34611 Oxygen Sensor for Infiniti J30

Walker Products 350-34611 is a heated oxygen sensor built as a specific-fit OE replacement for select Infiniti J30 applications. It is engineered to provide the ECU with the feedback needed for accurate fuel control and emissions monitoring on downstream left positions.

Key Features

• Heated oxygen sensor for faster operating response
• Specific fit for the correct vehicle application and mounting position
• 4-wire design with 20-gauge wiring
• Threaded mounting type with 18.0 mm thread diameter
• Radiused polygon male connector for proper harness connection
• Wiring harness length: 31.81 in.; overall length: 35.35 in.

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors developed as OE-style replacements for worldwide vehicle applications. Part number 350-34611 is built for the downstream left location on 1995 Infiniti J30 and 1996-1997 Infiniti J30 models. For buyers searching for a 1995 Infiniti J30 downstream left oxygen sensor or a 1996-1997 Infiniti J30 downstream left oxygen sensor, this part number 350-34611 matches the listed fitment and sensor configuration.

This sensor helps the engine control module monitor exhaust oxygen content so the system can maintain proper air-fuel strategy. Walker Products has supplied engine management components since 1946 and manufactures application-specific sensors to match the required fitment position and diagnostic feedback needs of the ECU. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Poor fuel economy caused by inaccurate exhaust feedback
• Rough engine operation from incorrect air-fuel correction
• Higher exhaust emissions from a failing downstream sensor
• Fault codes stored in the ECU for the affected sensor circuit

Installation Notes

Verify the downstream left position before installation on the Infiniti J30. Inspect the sensor wiring harness, connector, and surrounding exhaust components for heat damage, corrosion, or physical wear before replacement. Confirm thread size, connector shape, and wire count match the original sensor to ensure proper installation and ECU communication.

Quality Assurance

Walker Products manufactures this oxygen sensor as an application-specific replacement under its Walker Products Aftermarket line, with production supported by Automotive ISO9001/TS 16949 quality systems.
