• Specific fit for the listed Jaguar upstream positions
• 4-wire design with female radiused polygon connector
• Threaded mounting with 18.0 mm thread diameter
• Wiring harness length: 15.28 in.; overall length: 18.82 in.
• Walker Products Aftermarket part number 350-64058

Product Details

Walker Products Engine Management and Oxygen/Air-Fuel sensors are developed as OEM replacement parts for a wide range of vehicles. This Walker 350-64058 oxygen sensor is built for the specific application and fitment position so the ECU receives the correct diagnostic feedback. The Walker Products Aftermarket line focuses on engine management and sensor applications that match original equipment requirements for fit, connector configuration, and signal output.

Compatible With 1999-2003 Jaguar Vanden Plas, upstream left and upstream right; 1999-2003 Jaguar XJ8, upstream left and upstream right; 1999-2003 Jaguar XJR, upstream left and upstream right; 2000-2002 Jaguar XK8, upstream left and upstream right; and 2000-2002 Jaguar XKR, upstream left and upstream right. For 1999 Jaguar XK8, the listed upstream left and right applications apply from chassis #V031303.

Common Issues This Sensor Can Address

• Check engine light or malfunction indicator light related to oxygen sensor performance
• Poor engine operation caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel control
• Higher exhaust emissions from a failing upstream sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

Verify the vehicle year, model, and upstream left or upstream right position before installation. Inspect the sensor wiring harness and connector for damage, since physical wear can shorten service life and affect signal quality. On 1999 Jaguar XK8 applications, confirm chassis number V031303 when selecting the correct upstream sensor location.

Quality Assurance

Walker Products has produced engine management and fuel system components since 1946 and manufactures sensors under Automotive ISO9001/TS 16949 quality systems. Part number 350-64058 is built to support the diagnostic needs of the ECU in the listed Jaguar applications.
