Bosch 13374 Oxygen Sensor - Downstream Left, Downstream Rear or Downstream Right

Bosch Actual OE Oxygen Sensor 13374

Bosch 13374 is a specific-fit, narrow-band heated oxygen sensor built for accurate air-fuel ratio feedback to the ECU. It supports stable combustion control and emissions management in confirmed applications such as the 1999-2000 Nissan Maxima, 1999 INFINITI I30, and 2000-2002 Nissan Sentra.

Key Features

• Specific-fit oxygen sensor for direct application matching
• Narrow-band heated design for faster closed-loop operation
• 4-wire configuration with square male connector
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Wiring harness included with 36.9 in harness length
• Metal housing and high-temperature-resistant construction for demanding exhaust conditions
• Bosch Actual OE Oxygen Sensor line reflects Bosch OE development experience

Product Details

Bosch 13374 uses a switching-type narrow-band sensing element to report exhaust oxygen content to the engine control unit. Bosch’s OE-focused oxygen sensor line builds on decades of sensor development, including faster light-off and improved lambda accuracy from planar narrowband designs. This part cross-references Bosch OE-style applications such as 226A04L713 and 226A06M402 for the same application. For buyers searching for a Bosch oxygen sensor 13374 for Nissan Maxima or INFINITI I30, this sensor is a direct-match replacement for the listed downstream positions.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio feedback to the ECU
• Rough idle or unstable closed-loop fuel control
• Emissions test failures tied to downstream sensor faults
• Slow sensor response from an aging heated O2 sensor

Installation Notes

Install only in the confirmed downstream positions listed for each vehicle: Fits 1999-2000 Nissan Maxima, downstream left; Fits 1999 INFINITI I30, downstream right; Fits 2000-2001 INFINITI I30, downstream rear; Fits 2000-2002 Nissan Sentra, downstream right. Verify connector shape, wire count, thread size, and sensor location before installation. Use proper oxygen sensor service tools and follow factory torque specifications for the threaded mount.

Quality Assurance

Bosch supplies this Actual OE Oxygen Sensor line with OE-proven engineering, using durable ceramic sensing elements, controlled heater operation, and materials selected for heat and vibration resistance. Bosch 13374 is built to deliver consistent sensor output in the listed applications.
