Bosch 16207 Oxygen Sensor - Downstream

Overview

Bosch 16207 is an Actual OE oxygen sensor built as a specific-fit, threaded replacement for downstream applications. It uses a narrow-band heated design with a 4-wire harness to deliver accurate air-fuel feedback and stable closed-loop control.

Key Features

• Actual OE Oxygen Sensor line from Bosch
• Narrow-band heated sensor for precise switching-type signal output
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• 4-wire construction with oblong connector and pin terminals
• Metal housing and high-temperature materials for demanding exhaust conditions
• Wiring harness included for a direct replacement setup

Detailed Description

This Bosch oxygen sensor is engineered for accurate lambda measurement and consistent ECU feedback across changing exhaust temperatures and vibration loads. The heated narrow-band design promotes faster light-off and quicker closed-loop operation, helping the engine management system maintain stable combustion control and emissions performance. Bosch 16207 is a fitment-specific replacement for 2011-2018 Porsche Cayenne downstream applications, and it cross-references Porsche 95860617200 for the same application.

What It Helps Address

• Delayed or inaccurate oxygen sensor signal response
• Rough idle caused by incorrect air-fuel feedback
• Check engine light conditions related to sensor performance
• Reduced emissions control from a worn downstream sensor
• Slow closed-loop transition after startup

Installation Notes

Fits 2011-2018 Porsche Cayenne, downstream. Verify the threaded mounting style, 18 mm thread size, 4-wire connector layout, and harness length before installation. Use the existing mounting location and confirm connector orientation matches the vehicle harness. Bosch 16207 is a specific-fit oxygen sensor, so application matching should be checked against the original part number and sensor configuration.

Quality Assurance

Bosch draws on more than five decades of OE oxygen sensor development, and the Actual OE Oxygen Sensor line reflects that experience with OE-proven design and materials.
