Delphi ES10820 Oxygen Sensor O2 Sensor OE Replacement

The Delphi ES10820 is a direct-fit OE replacement oxygen sensor (O2 sensor / lambda sensor) engineered to restore precise exhaust gas monitoring and proper air-fuel ratio management. As a global OE manufacturer, Delphi builds every sensor to the same standards used in original vehicle production, delivering proven reliability in an aftermarket part.

Key Features:

• Patented planar sensor technology for fast activation and accurate exhaust oxygen measurement, supporting efficient engine performance
• Patented protective sensor coating shields the sensing element from silicone, phosphorous, and other fuel and oil additive contamination that can trigger check-engine lights or cause premature failure
• High-temperature water seal resists water intrusion, extreme heat, vibration damage, and wire corrosion to preserve signal accuracy and sensor longevity
• Direct-fit OE connectors and wire harness for straightforward, no-splice installation right out of the box
• High-temperature anti-seize compound included (pre-applied or in-box) to prevent the sensor from seizing in the bung
• Validated for all fuel types, including ethanol blends such as E85
• OE-tested to 150,000 miles, plus 2,000 hours of severe thermal testing

A failing O2 sensor can cause the engine to burn up to 25% more fuel and emit harmful exhaust pollutants. Replacing it with a quality OE-grade sensor like the Delphi ES10820 helps maintain optimal combustion efficiency, reduces emissions, and keeps the check-engine light off.
