Bosch 13311 Oxygen Sensor - Downstream, Upstream or Upstream Right

Bosch Actual OE Oxygen Sensor 13311

Bosch 13311 is a narrow-band heated oxygen sensor built for precise air-fuel ratio feedback to the ECU. It supports stable combustion control and emissions management across changing engine loads, making it a direct replacement choice for select Nissan, Infiniti, and Mercury applications.

The Bosch Actual OE Oxygen Sensor line draws on Bosch’s long OE development history, including early thimble-style sensors and later planar narrowband designs that improved warm-up speed, lambda accuracy, and closed-loop response. Bosch 13311 uses a ceramic sensing element, optimized heater control, and heat-resistant materials for consistent operation in demanding exhaust conditions.

• Specific-fit oxygen sensor for confirmed vehicle applications
• Narrow-band heated design for faster closed-loop operation
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• 3-wire configuration with blade terminals and male connector
• Wiring harness included for direct replacement use
• Standard replacement grade for emission control service

What It Helps Address

• Incorrect air-fuel ratio feedback to the engine control unit
• Slow oxygen sensor response during warm-up or closed-loop transition
• Check engine light concerns related to sensor performance
• Rough combustion control caused by aging upstream or downstream sensor output
• Emissions test failures tied to a worn narrow-band O2 sensor

Installation Notes

Verify the connector shape, wire count, mounting style, and sensor position before installation. Bosch 13311 is a threaded, heated narrow-band sensor with a specific fit, so it should be matched to the exact year, make, model, and position listed above. For Nissan Sentra, Nissan 200SX, Nissan 240SX, Nissan Frontier, Nissan Xterra, Infiniti G20, and Mercury Villager applications, confirm emission package and build-date notes where shown in the fitment list.

Use proper oxygen sensor service tools to avoid damaging the 18 mm threads or the exhaust bung. Inspect the harness routing and connector lock before final assembly, and clear any stored diagnostic trouble codes after installation if required by the vehicle service procedure.

Quality Assurance

Bosch backs this Actual OE Oxygen Sensor line with more than five decades of OE development experience. The design reflects Bosch’s focus on accurate sensing, durable heater control, and OE-proven materials for aftermarket replacement service.
