Bosch 13242 Oxygen Sensor - Upstream Left or Upstream Right

Bosch Actual OE Oxygen Sensor for Nissan and Infiniti

Bosch 13242 is a specific-fit, narrow-band heated oxygen sensor built for precise air-fuel ratio feedback to the ECU. It is an OE-style replacement for select 1995-1998 Nissan Maxima and 1996-1998 Infiniti I30 applications, including upstream left and upstream right positions.

Key Features

• Bosch Actual OE Oxygen Sensor line for OE-proven replacement performance
• Narrow-band heated O2 sensor for faster closed-loop operation
• Specific fit with wiring harness included
• 3-wire design with blade terminals and oblong connector
• Threaded mounting, 18 mm thread size, 22 mm hex size
• Metal housing with high-temperature-resistant construction
• Fits 1995-1997 Nissan Maxima, upstream left and upstream right
• Fits 1996-1998 Infiniti I30, upstream left and upstream right

Product Details

Bosch 13242 uses a switching-type narrow-band design to send accurate oxygen content data to the engine control unit, helping maintain stable combustion control and emissions performance. Bosch developed this sensor family from its long-running OE oxygen sensor engineering, including faster light-off and improved lambda accuracy through planar narrowband technology. For drivers searching for a Bosch 13242 oxygen sensor for Nissan Maxima or Infiniti I30 upstream locations, this part provides a direct replacement path with the correct connector, harness length, and threaded mounting style.

This part cross-references 2269040U06 and 2269040U16 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor circuit or response faults
• Rough idle or unstable air-fuel control
• Reduced fuel economy caused by inaccurate exhaust feedback
• Slow closed-loop transition after startup
• Emissions test failures tied to sensor performance

Installation Notes and Tips

Confirm the upstream left or upstream right position before ordering Bosch 13242. The sensor uses a threaded 18 mm mount, a 3-wire harness, and a male oblong connector with blade terminals. Inspect the exhaust bung threads and wiring routing during installation, and verify the connector matches the original sensor on your Nissan Maxima or Infiniti I30.

Quality Assurance

Bosch backs this Actual OE Oxygen Sensor line with more than five decades of OE development and aftermarket supply experience. The sensor is built with ceramic sensing elements, controlled heater operation, and durable materials selected for high thermal and vibration loads.
