Walker 350-34118 Oxygen Sensor - Upstream Left or Upstream Right

Walker 350-34118 Oxygen Sensor for Jaguar

Walker Products 350-34118 is a heated, threaded oxygen sensor built as a specific-fit OE-style replacement for select Jaguar applications. It is engineered to provide the ECU with the feedback needed for proper fuel control and emissions monitoring on upstream positions.

Key Features

• Heated oxygen sensor for faster operating response
• Specific-fit design for the listed Jaguar applications
• 4-wire configuration with 20-gauge wiring
• Radiused polygon male connector for vehicle-specific connection
• Threaded mounting with 18.0 mm thread diameter
• Wiring harness length: 13.31 in.; overall length: 16.85 in.

Product Details

Walker Products Aftermarket 350-34118 is part of the Walker Products Engine Management and Oxygen/Air-Fuel sensor line, which is built for OE replacement use across a wide range of vehicles. This sensor is designed for upstream right and upstream left locations on select 1997-1999 Jaguar XK8, 1998 Jaguar Vanden Plas, 1998 Jaguar XJ8, and 1998 Jaguar XJR applications. For buyers searching for a Jaguar XK8 upstream oxygen sensor or a 1998 Jaguar XJ8 oxygen sensor replacement, this part number provides a direct-fit option matched to the listed chassis and position requirements. This part cross-references Walker Products Aftermarket 350-34118 for the same application.

What It Helps Address

• Check engine light or malfunction indicator light related to oxygen sensor performance
• Rough engine operation caused by incorrect air-fuel feedback
• Increased fuel consumption from inaccurate exhaust gas readings
• Higher exhaust emissions from a failing upstream sensor
• Fault codes stored in the ECU tied to the affected sensor circuit

Installation Notes and Tips

Verify the vehicle position before installation: this part is listed for upstream right and upstream left locations only. Confirm connector shape, wire count, thread diameter, and harness length against the original sensor before replacement. Inspect the sensor wiring harness and connector for damage, since physical wear can shorten sensor life and affect ECU feedback. For fitment-specific searches, this is the correct style for 1997-1998 Jaguar XK8 upstream left or right, 1998 Jaguar Vanden Plas upstream right or left, and 1998 Jaguar XJR upstream right or left applications.

Quality Assurance

Walker Products states that its engine management sensors are developed as OE replacement parts and manufactured under Automotive ISO9001/TS 16949 certification standards. The brand has supplied engine management and fuel system components since 1946, with application-specific cataloging and fitment-focused engineering.
