Walker 350-64087 Oxygen Sensor

Walker 350-64087 Oxygen Sensor Overview

Walker Products 350-64087 is a heated, specific-fit oxygen sensor engineered as an OE-style replacement for select Nissan and INFINITI applications. It is built for the correct mounting position and ECU feedback requirements, helping restore accurate exhaust monitoring on vehicles such as the Nissan Altima, Sentra, Versa, Rogue, and Frontier.

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors for application-specific fitment. The 350-64087 follows that approach with a threaded, 4-wire design sized for the intended exhaust location and connector style.

Key Features

• Part number: 350-64087
• Heated oxygen sensor for faster operating response
• Specific fit for the listed Nissan and INFINITI applications
• 4-wire design with male connector
• Threaded mounting type with 18.0 mm thread diameter
• Wiring harness length: 13.31 in.
• Overall length: 16.85 in.
• Radiused polygon connector shape

Detailed Description

This Walker oxygen sensor is designed for direct replacement in select 2007-2010 Nissan and 2007 INFINITI vehicles, including upstream and upstream rear positions where specified. It supports ECU monitoring by delivering the exhaust feedback needed for fuel control and emissions management. For shoppers searching for a 2008-2010 Nissan Altima upstream oxygen sensor, a 2008-2010 Nissan Sentra Bank 1 Sensor 1 replacement, or a 2007 Nissan Frontier upstream sensor, this part number provides application-specific coverage.

Walker Products 350-64087 is also listed for select 2008-2009 Nissan Rogue and 2009 Nissan Sentra non-California emissions applications, plus 2007 Nissan Armada, TITAN, Xterra, 350Z, and INFINITI G35/QX56 upstream left or right positions where noted. This part cross-references Bosch (e.g., 15717) for the same application.

What It Helps Address

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

Installation Notes and Tips

Confirm the exact year, make, model, engine, emissions package, and sensor position before ordering. This part is specific to the listed upstream and upstream rear applications, and some Nissan Rogue and Sentra listings exclude California emissions-certified vehicles. Inspect the sensor wiring harness and connector for damage before installation, and verify the threaded mounting location matches the vehicle’s exhaust bung.

Quality Assurance

Walker Products manufactures engine management sensors as OE-replacement components for global vehicle applications and operates as an Automotive ISO9001/TS 16949 certified company. The 350-64087 is built to the specified application and position so the ECU receives the expected diagnostic feedback.
