Bosch 13348 Oxygen Sensor

Bosch OE Oxygen Sensor for Nissan and INFINITI

Bosch 13348 is a narrow-band heated oxygen sensor built for specific downstream applications on select Nissan and INFINITI vehicles. It provides air-fuel-ratio feedback to the ECU for stable closed-loop control, accurate combustion management, and lower emissions.

Compatible With 1999-2001 Nissan Maxima and 1999-2001 INFINITI I30 downstream positions, this Bosch Actual OE Oxygen Sensor is a direct-fit replacement for vehicles that use a threaded, 4-wire, square-connector design.

Key Features

• Specific-fit Bosch oxygen sensor for targeted downstream applications
• Narrow-band heated sensor design for faster closed-loop operation
• 4-wire configuration with blade terminals and square connector
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Wiring harness included with 29 in. harness length
• Metal housing and high-temperature-resistant construction
• Part number 13348 for accurate catalog matching

Product Details

Bosch 13348 uses advanced ceramic sensing elements and controlled heater operation to deliver consistent signal response under demanding exhaust temperatures and vibration. Bosch’s Actual OE Oxygen Sensor line draws on decades of OE development, including narrowband sensor designs that improved light-off speed and lambda accuracy for modern engine management systems. For drivers searching for a downstream oxygen sensor for 2001 Nissan Maxima or a downstream front oxygen sensor for 2000-2001 INFINITI I30, this part provides the OE-style fit and signal behavior expected for emission control service.

This part cross-references 226A14L715 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture readings at the ECU
• Slow closed-loop response after warm-up
• Emissions test failures tied to downstream sensor faults
• Rough combustion control caused by aging sensor output

Installation Notes and Tips

Verify the downstream position, connector shape, wire count, and threaded mounting style before installation. This Bosch 13348 oxygen sensor is specific fit, so confirm the vehicle year, model, and emission configuration against the listed applications: Fits 2000-2001 INFINITI I30, Downstream Front; Fits 1999 INFINITI I30, Downstream Left, with California Emission System; Fits 2001 Nissan Maxima, Downstream; Fits 1999-2000 Nissan Maxima, Downstream Right, with California Emission System. Use proper oxygen sensor service tools and inspect the harness routing to avoid heat damage.

Quality Assurance

Bosch backs this Actual OE Oxygen Sensor with OE-proven engineering developed over more than five decades of oxygen sensor design. The part is built to the same standard replacement expectations used in Bosch aftermarket emission control applications.
