Bosch 16324 Oxygen Sensor - Downstream Right

Bosch OE Oxygen Sensor for Mercedes-Benz

Bosch 16324 is a specific-fit, narrow-band heated oxygen sensor for downstream right placement on select Mercedes-Benz models. It provides air-fuel-ratio feedback to the ECU for stable closed-loop control and emissions monitoring.

• Specific-fit oxygen sensor for direct application matching
• Downstream right position for select Mercedes-Benz CLK320, CLK430, and CLK55 AMG
• Narrow-band heated sensor with 4-wire, pin-terminal design
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Wiring harness included for a cleaner replacement setup
• Metal housing and high-temperature-resistant construction for demanding exhaust conditions

Actual OE Sensor Line

Bosch Actual OE Oxygen Sensor parts are built from Bosch’s long OE development history in oxygen sensing technology. This line uses ceramic sensing elements and controlled heater operation to deliver fast warm-up, accurate lambda feedback, and consistent closed-loop response across changing exhaust temperatures. Bosch 16324 follows that OE-focused approach for Mercedes-Benz CLK320, CLK430, and CLK55 AMG applications.

This part cross-references Mercedes-Benz 0015407317 for the same application.

What It Helps Correct

• Check engine light related to oxygen sensor performance
• Rich or lean fuel trim readings from the downstream sensor circuit
• Slow sensor response during closed-loop operation
• Emissions test failures tied to exhaust feedback faults
• Rough combustion control caused by inaccurate air-fuel ratio data

Installation Notes

Fits 2001-2003 Mercedes-Benz CLK320, downstream right. Fits 2001-2003 Mercedes-Benz CLK430, downstream right. Fits 2001-2002 Mercedes-Benz CLK55 AMG, downstream right. Confirm connector shape, thread size, and sensor position before installation. Use the threaded mounting point and route the included harness away from heat and moving components.

Quality Assurance

Bosch supplies this oxygen sensor as an OE-style replacement backed by more than five decades of oxygen-sensor development and aftermarket support. Bosch 16324 is built to the same performance expectations associated with Bosch OE sensor engineering.
