Bosch 13350 Oxygen Sensor - Upstream Rear or Upstream Right

Bosch Actual OE Oxygen Sensor 13350

Bosch 13350 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 for select Nissan Maxima and INFINITI I30 applications.

Key Features

• Specific-fit oxygen sensor for direct application matching
• Narrow-band heated design for faster closed-loop operation
• Blade terminal, 3-wire configuration with included wiring harness
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Metal housing and high-temperature-resistant construction for demanding exhaust conditions
• Oblong male connector with male terminals for OE-style connection

Product Details

This Bosch Actual OE Oxygen Sensor line reflects Bosch’s long OE development history in oxygen sensing technology, including narrowband planar designs that improve light-off response and lambda measurement accuracy. Part number 13350 uses a heated narrow-band sensor element to deliver consistent signal output across changing exhaust temperatures, helping the engine control module maintain proper fuel control. It is a direct replacement for upstream rear and upstream right locations on 2000-2001 INFINITI I30 and 2000-2001 Nissan Maxima applications. This part cross-references 226902Y921 for the same application.

Common Issues This Sensor Can Address

• Check engine light related to oxygen sensor performance
• Rich or lean fuel mixture faults caused by inaccurate exhaust feedback
• Delayed closed-loop fuel control after startup
• Reduced emissions performance from a worn upstream sensor
• Driveability concerns tied to unstable air-fuel ratio readings

Installation Notes and Tips

Verify the connector shape, terminal count, thread size, and sensor position before installation. Bosch 13350 is a threaded, heated narrow-band sensor with a 22 mm hex size and 18 mm thread diameter, so proper removal and installation tools are important. Confirm the vehicle uses the listed upstream rear or upstream right location on the exact model year before replacing the sensor.

Quality Assurance

Bosch supplies OE-proven oxygen sensor technology to the aftermarket, drawing on more than five decades of development in air-fuel sensing and emissions control. The 13350 is built to the same standard replacement expectations used for select OE applications.
