Bosch 13264 Oxygen Sensor - Downstream or Downstream Right

Bosch Actual OE Oxygen Sensor 13264

Bosch 13264 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 in the downstream right position on select Infiniti and Nissan applications, including the Pathfinder and QX4.

Key Features

• Actual OE Oxygen Sensor from Bosch
• Narrow-band heated design for faster closed-loop operation
• Specific fit sensor with threaded mounting
• 4-wire configuration with square male connector
• 30 in wiring harness length with included harness
• 18 mm thread diameter and 22 mm hex size
• Metal housing with high-temperature-resistant construction

Product Details

Bosch’s Actual OE Oxygen Sensor line draws on decades of original equipment development, including narrowband switching-type designs that measure exhaust oxygen content and send accurate feedback to the engine control unit. Part number 13264 uses a heated sensor element and optimized heater control to help the sensor reach operating temperature quickly and maintain consistent signal quality under thermal and vibration stress. For drivers servicing a Nissan Pathfinder oxygen sensor or Infiniti QX4 downstream right oxygen sensor, this Bosch replacement matches the specific fit and OE-style configuration needed for direct service.

This part cross-references 226A00W012 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio feedback to the ECU
• Rough idle or unstable combustion control from a failing downstream sensor
• Emissions test failures tied to sensor response issues
• Slow closed-loop operation after sensor aging or contamination

Installation Notes

Fits 1997-2000 INFINITI QX4, downstream right. Fits 1996-2000 Nissan Pathfinder, downstream right. Fits 2000 Nissan Pathfinder, downstream right, for vehicles built to 12/1999 or from 01/2000 as listed in the fitment data. Fits 1997-1998 Nissan 240SX, downstream. Verify connector shape, thread size, and sensor position before installation. Use the threaded mounting point and the existing harness routing to match the original layout.

Quality Assurance

Bosch backs this oxygen sensor with OE development experience and materials selected for consistent performance in demanding exhaust environments. The Bosch 13264 is built as a standard replacement part with OE-proven design principles for reliable service.
