The DELPHI Mass Air Flow (MAF) Sensor, part number AF10407-12B1, is engineered to precisely measure the amount of air entering your engine's intake manifold. This critical data is then sent to the engine control unit (ECU) to calculate the correct amount of fuel to inject, leading to improved fuel efficiency and reduced emissions. Proper functioning of the MAF sensor is vital for maintaining smooth engine operation. A faulty sensor can lead to various drivability issues, including rough idling, hesitation, stalling, and a decrease in overall power. Replacing a worn or malfunctioning sensor with a reliable DELPHI unit like the AF10407-12B1 can restore your vehicle's performance and efficiency. DELPHI is a trusted name in automotive components, known for producing high-quality parts that meet or exceed original equipment specifications. This MAF sensor is designed for a direct fit, ensuring a straightforward installation process. Ensure your engine receives the correct air-fuel mixture for optimal combustion and longevity.
