The DELPHI AF10500-12B1 Mass Air Flow (MAF) sensor is engineered to precisely measure the volume and density of air entering your vehicle's engine. This critical data is transmitted to the engine control unit (ECU) to calculate the correct amount of fuel to inject for optimal combustion. Accurate air flow readings are essential for maintaining engine performance, fuel efficiency, and reducing emissions. A malfunctioning MAF sensor can lead to poor acceleration, rough idling, increased fuel consumption, and illuminated check engine lights. This DELPHI MAF sensor is designed to meet or exceed original equipment specifications, ensuring reliable and consistent performance. Its robust construction and advanced sensing technology provide durability and accuracy, helping to restore your engine's performance to its intended state.
