Delphi AF10781 Mass Air Flow Sensor MAF Sensor

The Delphi AF10781 Mass Air Flow Sensor is a direct-fit, all-new MAF sensor engineered to OE specifications — delivering the same precision and reliability as the original equipment part it replaces. Also commonly referred to as an air meter or MAF sensor, this unit measures the volume and velocity of air entering the engine's intake system and relays that data to the engine control module (ECM).

Key Features:

• All-new construction — never remanufactured; built with calibrated, all-new components to eliminate the risk of contamination or inaccurate readings
• OE-calibrated performance — tested and calibrated using highly accurate OE equipment to meet or exceed original equipment specifications
• Fast response time — typically less than 15 milliseconds to 90% of flow change for precise, real-time air measurement across a wide range of ambient temperatures
• Dual heated elements — allows integration into any platform's air/fuel system regardless of ducting assembly configuration
• Multiple sensing elements — eliminates sensitivity to supply voltage fluctuations and noise on power ground lines
• Cold-weather rated — cold sealing rated to -50°C for reliable performance in extreme conditions
• Includes installation hardware — ships with a driver bit and screws to streamline installation
• Protected packaging — arrives in a plastic clamshell to safeguard sensitive sensing elements during shipping and handling

By providing the ECM with continuous, accurate information on airflow, the Delphi AF10781 helps optimize the air-fuel ratio, supporting improved fuel economy, reduced emissions, and responsive engine performance. With over 100 years of OE manufacturing experience and more than 50 million MAF sensors delivered across 500+ vehicle applications, Delphi is a trusted name in engine management technology.
