Bosch 13367 Oxygen Sensor - Upstream

Bosch Validated Oxygen Sensor for Hyundai

Bosch Validated Oxygen Sensor 13367 is a specific-fit, narrow-band heated oxygen sensor for upstream applications on select Hyundai models. It provides precise air-fuel-ratio feedback to the ECU to support stable combustion control and lower emissions.

Key Features

• Specific-fit oxygen sensor for direct application matching
• Narrow-band heated sensor design for faster closed-loop operation
• 4-wire configuration with blade terminals and rectangle connector
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Wiring harness included for a cleaner replacement setup
• Metal housing built for high-temperature and vibration exposure
• Fits 1998-2001 Hyundai Tiburon, upstream
• Fits 1998-2000 Hyundai Elantra, upstream
• Fits 1998-1999 Hyundai Accent, upstream
• Fits 1997 Hyundai Accent, upstream, from 05/1997

Product Details

Bosch 13367 is part of the Bosch Validated Oxygen Sensor line, which builds on Bosch OE oxygen sensor development dating back to the original thimble sensor and later planar narrowband designs. This sensor uses advanced ceramic elements, optimized heater control, and high-temperature-resistant materials to deliver consistent signal accuracy under demanding thermal and vibration conditions. For Hyundai Tiburon, Hyundai Elantra, and Hyundai Accent upstream locations, Bosch 13367 supports accurate exhaust feedback where the engine management system needs it most.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Sensor May Address

• Check engine light related to oxygen sensor performance
• Unstable air-fuel ratio readings at the ECU
• Rough idle caused by inaccurate upstream exhaust feedback
• Increased emissions from delayed closed-loop response
• Poor fuel control from a worn narrow-band sensor

Installation Notes and Tips

Confirm upstream placement before installation and verify the connector shape, wire count, and thread size against the original sensor. The threaded design uses an 18 mm thread diameter and 22 mm hex size. Inspect the harness routing and connector lock before final assembly, and clear diagnostic trouble codes after replacement if required by the vehicle.

Quality Assurance

Bosch backs this oxygen sensor with more than five decades of OE development and aftermarket supply experience. Bosch Validated Oxygen Sensor 13367 is built to OE-proven standards for accurate signal delivery and durable operation in demanding exhaust environments.
