Bosch 13313 Oxygen Sensor - Upstream

Bosch Actual OE Oxygen Sensor for Jaguar

Bosch 13313 is an Actual OE Oxygen Sensor built for precise air-fuel-ratio feedback to the ECU. This narrow-band heated sensor supports stable combustion control and emissions management for select Jaguar applications, including upstream service on Vanden Plas, XJ6, XJ12, XJS, and XJRS models.

Key Features

• Actual OE Oxygen Sensor from Bosch’s OE-focused product line
• Narrow-band heated design for faster closed-loop operation
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Specific-fit sensor with 3-wire harness and included wiring harness
• Metal housing built for high-temperature and vibration exposure
• Rectangle/round connector with blade pin terminals

Product Details

Bosch 13313 uses a switching-type narrow-band design to report exhaust oxygen content to the engine control unit, helping maintain the correct air-fuel mixture during normal driving and warm-up conditions. Bosch developed this sensor family from its long-running OE oxygen sensor engineering, including planar narrowband technology that improves light-off speed, lambda accuracy, and closed-loop response. For Jaguar owners searching for an upstream oxygen sensor for 1992-1994 Jaguar Vanden Plas, 1992-1994 Jaguar XJ6, or 1994 Jaguar XJ12, this part provides an OE-style replacement built around the original application requirements. This part cross-references Monroe Shocks & Struts (e.g., DBC10744) for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rich or lean fuel mixture readings at the ECU
• Slow sensor response during closed-loop operation
• Emissions test failures tied to upstream sensor output
• Rough idle or unstable combustion control from inaccurate exhaust feedback

Installation Notes

Verify upstream location, connector style, and thread size before installation. Bosch 13313 uses a threaded 18 mm mounting design with a 32.2 in wiring harness length and a 35.9 in overall length. Confirm the vehicle-specific fitment for 1992-1994 Jaguar Vanden Plas, 1994 Jaguar XJ12, 1992-1994 Jaguar XJ6, 1992-1994 Jaguar XJS, and 1993-1994 Jaguar XJRS, including the 1993-1994 XJS chassis note where applicable.

Quality Assurance

Bosch backs this oxygen sensor with more than five decades of OE development in emission control sensing. The design uses advanced ceramic elements, controlled heating, and high-temperature-resistant materials to maintain consistent signal output under thermal and vibration load.
