- Steel-finish metal housing for high-temperature service
- Bosch part number 13860 for OE-style replacement identification
Product Details
Bosch’s Actual OE Oxygen Sensor line draws on decades of original-equipment development, including narrowband sensor designs that improve light-off response and lambda measurement accuracy. Bosch 13860 uses a heated sensing element and optimized heater control to deliver consistent signal output under changing exhaust temperatures and vibration loads. For Mercedes-Benz E320 owners searching for an upstream oxygen sensor replacement, Bosch 13860 provides the OE-style fit and sensor behavior expected in emission control service.
This part cross-references Mercedes-Benz 0005408917 for the same application. Bosch 13860 is a direct-fit choice for the 1997 Mercedes-Benz E320, upstream, when replacing a worn or slow-switching sensor.
What It Helps Address
- Check engine light related to oxygen sensor performance
- Rich or lean fuel trim conditions caused by inaccurate exhaust feedback
- Slow closed-loop response during warm-up and normal driving
- Reduced emissions control from an aging upstream sensor
- Unstable idle or drivability concerns tied to air-fuel ratio correction
Installation Notes
Install Bosch 13860 in the threaded upstream oxygen sensor location on the 1997 Mercedes-Benz E320. Confirm connector shape, wire count, and thread size before installation, and route the harness away from exhaust heat and moving components. Use proper oxygen sensor service tools to avoid damaging the sensor body or threads.
Quality Assurance
Bosch supplies this Actual OE Oxygen Sensor line with OE-proven design principles, including ceramic sensing elements, durable heater control, and high-temperature-resistant materials. Bosch 13860 is built to meet the demands of emission control service on the Mercedes-Benz E320 and similar OE applications.
