Make TOPRAN

This Mass Air Flow (MAF) sensor from TOPRAN is designed to accurately measure the volume and density of air entering your vehicle's engine. Proper air measurement is essential for the engine control unit (ECU) to calculate the correct amount of fuel to inject, ensuring efficient combustion and optimal performance. Replacing a faulty MAF sensor can resolve issues such as rough idling, poor acceleration, increased fuel consumption, and check engine lights. This part ensures your engine receives the precise air-fuel ratio it needs to run smoothly and efficiently, contributing to better overall drivability and emissions control.
