Delphi AF10531 Mass Air Flow Sensor OE-Grade Replacement

The Delphi AF10531 is a direct-fit, OE-grade mass air flow (MAF) sensor engineered to restore accurate airflow measurement to your engine management system. Delphi draws on over 100 years of original equipment manufacturing experience as a Tier 1 supplier to the world's leading automakers, ensuring every aftermarket component meets or exceeds the same standards as the part that came on the vehicle from the factory.

The mass air flow sensor plays a critical role in your vehicle's fuel management system by measuring the volume and density of air entering the engine. This data is relayed to the engine control module (ECM), which uses it to calculate the precise fuel delivery needed for optimal combustion. A faulty MAF sensor can result in rough idle, poor fuel economy, hesitation under acceleration, and illuminated check engine lights — symptoms this Delphi replacement is designed to eliminate.
