Bosch 16110 Oxygen Sensor - Downstream

Bosch OE Oxygen Sensor for Macan

Bosch 16110 is an Actual OE Oxygen Sensor built as a narrow-band heated replacement for precise air-fuel-ratio feedback to the ECU. It supports stable combustion control and emissions management for the 2017-2018 Porsche Macan, downstream.

The Bosch Actual OE Oxygen Sensor line draws on Bosch’s long OE development history, including early thimble-style sensors and later planar narrowband designs that improved warm-up speed, lambda accuracy, and closed-loop response. Bosch 16110 continues that OE-focused approach with a threaded metal housing, integrated wiring harness, and high-temperature materials for consistent operation in demanding exhaust conditions.

• Specific-fit oxygen sensor for the 2017-2018 Porsche Macan, downstream
• Narrow-band heated sensor for direct exhaust feedback to the ECU
• 4-wire design with blade terminals and oblong connector
• Threaded 18 mm mounting with 22 mm hex size
• Wiring harness included for a direct replacement layout
• Standard replacement grade from Bosch Actual OE Oxygen Sensor line
• Cross-reference: 8K0906262G for the same application

Detailed Product Overview

Bosch 16110 is engineered for downstream oxygen-sensor service on the Porsche Macan, where accurate exhaust-gas monitoring helps the engine control module maintain proper fuel delivery and emissions performance. As a narrow-band heated sensor, it reaches operating temperature quickly and maintains stable signal output across changing thermal and vibration loads. The Bosch Actual OE Oxygen Sensor line is built around OE-style sensor architecture and materials, making this part a direct-fit choice for Macan owners replacing a worn or slow-responding downstream sensor.

Common Issues This Sensor Can Address

• Check engine light related to downstream oxygen sensor performance
• Slow or unstable oxygen sensor signal response
• Incorrect air-fuel feedback affecting combustion control
• Emissions test failures tied to sensor degradation
• Rough running or fuel-trim concerns caused by inaccurate exhaust readings

Installation Notes and Tips

Confirm the downstream location before installation and verify the 18 mm thread size, 22 mm hex, and 4-wire connector layout match the original sensor. Inspect the exhaust bung threads and connector condition before tightening the new sensor. Because this is a threaded oxygen sensor, proper removal and installation tools help reduce the risk of thread damage during service.

Quality Assurance

Bosch has more than five decades of OE oxygen-sensor development behind this part, and Bosch 16110 reflects that OE-proven engineering approach. It is built for consistent signal accuracy, heated operation, and durable performance in harsh exhaust environments.
