Bosch 16285 Oxygen Sensor - Downstream

Bosch Actual OE Oxygen Sensor for Porsche 911

Bosch 16285 is a narrow-band heated oxygen sensor built for precise air-fuel-ratio feedback to the ECU. It is a specific-fit downstream sensor for 2012-2016 Porsche 911 models, helping maintain stable closed-loop fuel control and lower emissions under changing operating conditions.

Key Features

• Specific-fit Bosch Actual OE Oxygen Sensor for downstream placement
• Narrow-band heated O2 sensor for accurate lambda feedback
• 4-wire design with included wiring harness and oblong male connector
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Metal housing and high-temperature-resistant construction for demanding exhaust environments
• Wiring harness length: 28.5 in; overall length: 31.9 in

Product Details

Bosch 16285 uses advanced ceramic sensing elements and controlled heater operation to deliver fast sensor response and consistent signal output. As part of Bosch’s Actual OE Oxygen Sensor line, it reflects the company’s long OE development history and narrow-band sensor expertise. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible with 2012-2016 Porsche 911, downstream. Use Bosch 16285 when replacing a worn sensor that is affecting fuel trim control, emissions performance, or exhaust feedback on your Porsche 911.

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Unstable air-fuel mixture control in closed-loop operation
• Slow sensor response after warm-up
• Elevated emissions from inaccurate exhaust feedback
• Rough fuel trim behavior caused by a degraded downstream sensor

Installation Notes and Tips

Verify downstream location, connector shape, wire length, and thread size before installation. Inspect the exhaust bung threads and wiring routing before tightening the sensor to the specified torque. Because this is a specific-fit sensor, confirm the Porsche 911 model year and position match the vehicle application exactly. Bosch 16285 is also referenced by part number 16285 for ordering and catalog lookup.

Quality Assurance

Bosch draws on more than five decades of OE oxygen sensor development, including switching-type and planar narrowband designs used to improve light-off speed, lambda accuracy, and closed-loop operation. Bosch 16285 is built to OE-style standards for consistent performance in high heat and vibration conditions.
