Bosch OE Oxygen Sensor for Infiniti J30
Bosch Actual OE Oxygen Sensor 13329 is a narrow-band heated O2 sensor built for precise air-fuel-ratio feedback to the ECU. It supports stable combustion control and emissions management for the 1993-1995 Infiniti J30, including the upstream left position.
Key Features
- Actual OE Oxygen Sensor from Bosch
- Narrow-band heated sensor design for faster closed-loop response
- Specific fit for the upstream left location on select Infiniti J30 applications
- 3-wire configuration with included wiring harness
- Threaded mounting with 18 mm thread diameter and 22 mm hex size
- Metal housing with high-temperature-resistant construction
- Oblong male connector with blade terminals
Product Details
Bosch 13329 uses a switching-type oxygen sensor design to measure exhaust oxygen content and send accurate feedback to the engine control unit. Bosch developed this OE-style sensor line from its long-running oxygen sensor engineering, including planar narrowband technology that improves light-off speed, lambda accuracy, and closed-loop operation. For drivers servicing a 1993-1995 Infiniti J30, this sensor is a direct-fit replacement for the upstream left location and is built to maintain consistent signal quality under heat and vibration.
This part cross-references B269010Y10 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 caused by inaccurate exhaust oxygen readings
- Reduced fuel control precision during closed-loop operation
- Emissions test failures tied to a worn upstream O2 sensor
Installation Notes
Fits 1993-1994 Infiniti J30, upstream left. Fits 1995 Infiniti J30, upstream left, to 09/1994; Actual OE Oxygen Sensor. Verify connector shape, 3-wire layout, and threaded mounting before installation. Use the correct 22 mm hex tool and 18 mm thread specification when removing or installing the sensor.
Quality Assurance
Bosch backs this oxygen sensor with more than five decades of OE development and aftermarket supply experience. The 13329 is built to Bosch OE standards for accurate signal output, durable heater performance, and dependable operation in demanding exhaust conditions.
