Detailed Description
Delphi ES10574 is an emission control sensor engineered for vehicles that require a heated O2 sensor with the listed connector and thread specifications. It is a direct replacement option for Mercedes-Benz E320, S320, and SL320 models in the fitment data, including 1995-1996 Mercedes-Benz E320 front and rear, 1996 Mercedes-Benz S320 rear, and 1996 Mercedes-Benz SL320 rear.

This part cross-references Bosch (e.g., 13597, 13599) for the same application.
What It Helps Address
- Check engine light related to oxygen sensor performance
- Incorrect air-fuel ratio readings
- Rough idle or hesitation caused by faulty exhaust feedback
- Failed emissions inspection tied to sensor output issues
- Slow sensor response from an aging heated oxygen sensor
Installation Notes and Tips
Verify the sensor position before ordering, since the fitment includes front and rear locations. Confirm connector shape, wire count, and thread size against the original part on your Mercedes-Benz E320, S320, or SL320. Follow the vehicle service procedure for exhaust sensor removal and installation, and route the harness away from heat and moving components.
Quality Assurance
Delphi draws on more than 100 years of OE experience and supplier knowledge used by major automakers, with that heritage carried into its aftermarket parts. The ES10574 is built to meet the application requirements listed above for Mercedes-Benz emissions service.
