Bosch 16369 Oxygen Sensor - Downstream

Bosch OE Oxygen Sensor for Porsche 911

Bosch Part Number 16369 is a specific-fit, narrow-band heated oxygen sensor for the downstream position on select 2014-2019 Porsche 911 models. It provides precise air-fuel-ratio feedback to the ECU to support stable combustion control and lower emissions.

Built on Bosch Actual OE Oxygen Sensor engineering, this replacement uses a threaded metal housing, a 4-wire harness, and a female oblong connector for direct-fit service on the Porsche 911 downstream application.

Key Features

• Specific-fit oxygen sensor for the downstream position
• Narrow-band heated sensor design for closed-loop fuel control
• 4-wire configuration with included wiring harness
• Threaded 18 mm mounting with 22 mm hex size
• Metal housing for high-temperature and vibration resistance
• Direct replacement for Bosch 16369 applications

Product Details

Bosch 16369 is part of the Actual OE Oxygen Sensor line, which reflects Bosch’s long history of OE sensor development. Bosch pioneered early oxygen sensor technology and later advanced planar narrowband designs to improve light-off response, lambda accuracy, and closed-loop operation. For the Porsche 911, this downstream sensor helps the engine management system monitor exhaust oxygen content after the catalyst, supporting accurate emissions control and consistent drivability.

This part cross-references 9A160619180 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rough idle caused by inaccurate air-fuel feedback
• Increased emissions from a worn downstream sensor
• Delayed closed-loop operation after startup
• Fuel trim issues tied to degraded sensor response

Installation Notes

Fits 2014-2019 Porsche 911, downstream. Confirm the connector shape, 4-wire layout, and 18 mm thread size before installation. The sensor is heated and uses a threaded mount; inspect the exhaust bung and wiring route for heat damage, corrosion, or thread contamination before fitting Bosch Part Number 16369.

Quality Assurance

Bosch backs this Actual OE Oxygen Sensor with OE-proven engineering and durable materials selected for harsh thermal and vibration loads. The design follows Bosch’s established oxygen sensor development standards for accurate signal output and consistent performance in aftermarket service.
