Walker 350-64045 Oxygen Sensor

Walker 350-64045 Oxygen Sensor Overview

Walker Products 350-64045 is a heated oxygen sensor built as a specific-fit OE-style replacement for select Nissan and INFINITI applications. It is engineered to provide the ECU with the exhaust feedback needed for accurate fuel control and emissions monitoring.

Compatible With 2008 INFINITI G37 upstream left and upstream right positions, plus 2009-2010 Nissan Murano upstream front and upstream rear positions. The Walker Products Aftermarket line focuses on application-specific engine management and oxygen/air-fuel sensors for direct-fit service work.

Key Features

• Heated oxygen sensor design for faster operating response
• Specific-fit construction for the listed vehicle and position
• 4-wire configuration with male connector
• Threaded mounting type with 18.0 mm thread diameter
• Wiring harness length: 12.32 in.
• Overall length: 15.87 in.
• Walker Products part number 350-64045

Detailed Description

Walker Products 350-64045 is designed for exhaust systems that require a direct replacement oxygen sensor with the correct connector, harness length, and mounting style. As an upstream sensor, it helps the engine control module monitor exhaust oxygen content so the ECU can adjust air-fuel delivery and maintain proper system feedback. This part number is listed for 2008 INFINITI G37 upstream left and upstream right, as well as 2009-2010 Nissan Murano upstream front and upstream rear applications.

Walker Products Aftermarket sensors are developed around specific vehicle applications rather than universal fitment, which helps match the original sensor location and electrical interface. If your vehicle has a fault code related to the oxygen sensor circuit, fuel trim, or emissions performance, verifying the sensor, wiring harness, and connector condition is an important first step. Walker Products 350-64045 is a practical replacement choice for service on the INFINITI G37 and Nissan Murano when the original upstream sensor has failed or is reporting incorrect feedback.

What It Helps Address

• Check engine light related to upstream oxygen sensor faults
• Poor engine performance caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel control
• Higher exhaust emissions from a failing sensor
• Diagnostic trouble codes stored in the ECU for sensor-related issues

Installation Notes and Tips

Confirm the exact position before ordering, since this part is listed for upstream front, upstream rear, upstream left, and upstream right locations depending on application. Inspect the sensor connector, harness, and nearby wiring for heat damage, corrosion, or abrasion before installation. Threaded mounting requires proper removal and installation practices to avoid damaging the exhaust bung or sensor threads.

For fitment verification, use the vehicle year, make, model, and sensor position exactly as listed: Fits 2008 INFINITI G37, upstream left; Fits 2008 INFINITI G37, upstream right; Fits 2009-2010 Nissan Murano, upstream front; Fits 2009-2010 Nissan Murano, upstream rear. This part cross-references Bosch (e.g., 15733) for the same application.

Quality Assurance

Walker Products has produced engine management and oxygen sensor components since 1946 and operates as an ISO 9001/TS 16949 certified company. Part number 350-64045 is built for the specified application and position to support the diagnostic feedback expected by the ECU.
