The DELPHI AF10230-12B1 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 then sent to the engine control unit (ECU) to determine the correct amount of fuel to inject for efficient combustion. Proper functioning of the MAF sensor is vital for maintaining engine performance, fuel economy, and reducing emissions. A faulty MAF sensor can lead to various drivability issues, including rough idling, hesitation, stalling, and poor acceleration. Replacing a worn or malfunctioning sensor with a high-quality part like this DELPHI unit helps restore your engine's optimal performance. This sensor is designed to meet or exceed original equipment specifications, ensuring a reliable fit and function. Its robust construction is built to withstand the harsh conditions within the engine bay, providing long-lasting service.
