NTK 25616 O2 sensor for the 2003-2011 Mercedes-Benz G55 AMG V8 5.5L and other vehicles reads exhaust oxygen and reports it to the ECU. That feedback helps the ECU control the air-fuel ratio and lets OBDII flag fuel delivery or catalytic converter problems.
- Heated, narrow-band switching zirconia design
- Updated to reduce failures of the original sensor and to improve durability
- Vibration and thermal shock testing during development, plus testing during manufacturing
- Water-resistant connectors and harness accessory hardware for easy installation
- 3-stage contaminant-resistant plasma jet and deposit trap overcoat protects the element against poisoning
- Dual-coated platinum interface and ceramic element designed for quick light-off and response times
Quick facts
- Part: NTK 25616 O2 sensor
- Also called: oxygen sensor
- Fits: 2003-2011 Mercedes-Benz G55 AMG V8 5.5L and other vehicles
- Condition: New
A worn sensor can show up as a check engine light, rough running or a change in fuel economy. Before you replace this sensor, rule out wiring damage, an exhaust leak near it and misfires, since each can set off similar codes.

Frequently Asked Questions
Does the NTK 25616 fit the 2003-2011 Mercedes-Benz G55 AMG V8 5.5L?
Yes. NTK 25616 fits the 2003-2011 Mercedes-Benz G55 AMG V8 5.5L, and that vehicle takes one sensor.
Is this NTK OE type oxygen sensor heated?
Yes. NTK 25616 is a heated, narrow-band switching zirconia sensor with a 7/8" (22 mm) hex and an M18 - 1.5 thread.
What protects the ceramic element of this sensor from contamination?
A 3-stage contaminant-resistant plasma jet and deposit trap overcoat protects the element against poisoning. The interface is dual-coated platinum.
Can a check engine light point to a worn O2 sensor?
It can be one cause, since OBDII watches this sensor's signal for fuel delivery and catalytic converter problems. A shop can read the codes and test the sensor.
What testing does the NTK 25616 go through?
Development includes vibration and thermal shock testing, and the sensor is also tested during manufacturing.
