The DELPHI AF10365-12B1 Air Mass Meter is a critical component for modern engine management systems. It precisely measures the volume and density of air entering the engine, providing vital data to the Engine Control Unit (ECU). This accurate measurement allows the ECU to calculate the correct amount of fuel to inject, ensuring optimal combustion. By maintaining the correct air-fuel ratio, the AF10365-12B1 contributes to improved fuel economy, reduced emissions, and consistent engine power delivery. Crafted with high-quality materials and engineered to meet stringent standards, this air mass meter offers reliable performance and durability. Replacing a faulty air mass meter can resolve issues such as rough idling, poor acceleration, increased fuel consumption, and check engine lights.
