Delphi ES10568 Oxygen Sensor Lambda Sensor - O2

The Delphi ES10568 is a direct-fit oxygen sensor (O2 sensor / lambda sensor) engineered to OE specifications. The oxygen sensor monitors the level of oxygen in the exhaust stream, providing critical feedback to the engine control unit to maintain the optimal air-to-fuel ratio for clean, efficient combustion. An underperforming or failed O2 sensor can result in increased fuel consumption, elevated emissions, and a triggered check engine light.

Key Features:

• OE-Grade Planar Technology: Delphi planar sensors deliver faster activation times and reach operating temperature in as little as six seconds, enabling quicker closed-loop operation and reduced cold-start emissions.
• Patented Contamination-Resistant Coating: Delphi's proprietary sensor coating provides superior resistance to silicone, phosphorous, and other fuel and oil additives — a leading cause of O2 sensor failure.
• E85 / Alcohol-Fuel Compatible: The unique sensor coating is designed for lifetime operation with E85 and other alcohol-based fuel blends.
• High-Temperature Water Seal: Protects the ceramic sensing element against water intrusion, extreme heat, vibration damage, and wire corrosion to preserve long-term signal accuracy.
• Direct-Fit OE Connector and Harness: Includes a vehicle-specific OE-style connector and correct wire length for a straightforward, plug-and-play installation without splicing.
• Anti-Seize Compound Included: High-temperature anti-seize compound is pre-applied or included in the box to prevent the sensor from seizing in the exhaust bung over time.
• Always New — Never Remanufactured: Every Delphi oxygen sensor is built new to OE standards and tested for accurate, reliable readings right out of the box.

Delphi is a global OE supplier to the world's top automakers, bringing over 100 years of engineering experience to every aftermarket part. The ES10568 is also sold under the suffix ES10568-12B1 (European/lambda market variant).
