The DELPHI Mass Air Flow (MAF) Sensor, part number AF10804-12B1, is engineered to precisely measure the amount of air entering your engine's intake system. This critical data is sent to the engine control unit (ECU) to determine the correct fuel injection rate, ensuring efficient combustion and optimal engine operation. Proper functioning of the MAF sensor is vital for maintaining fuel economy, reducing emissions, and preventing engine performance issues such as hesitation, stalling, or rough idling. DELPHI's commitment to quality means this sensor is built to meet or exceed original equipment specifications, providing reliable and consistent performance. Replacing a faulty MAF sensor with this DELPHI unit can restore your vehicle's power, improve throttle response, and help pass emissions tests. It is designed for a direct fit, simplifying the installation process for mechanics and DIY enthusiasts alike.
