The DELPHI Mass Air Flow (MAF) Sensor, part number AF10300-12B1, is engineered to precisely measure the amount of air entering your engine's intake manifold.

Proper functioning of the MAF sensor is vital for maintaining optimal engine performance, fuel economy, and emissions control. A faulty sensor can lead to various drivability issues, including rough idling, hesitation, stalling, and reduced power. Replacing a worn or malfunctioning MAF sensor with a quality part like this DELPHI unit can restore your vehicle's performance and efficiency.
