Bosch Mass Air Flow Sensor MAF

The Bosch Mass Air Flow Sensor (MAF), also called a MAF sensor or air mass meter, measures the amount of air entering the engine. It sends that data to the engine control unit (ECU). The ECU uses the signal to calculate fuel delivery and ignition timing, which helps the engine run efficiently and keeps emissions under control.

Key Features:

• Measures intake air mass accurately so the ECU can manage the air-fuel ratio
• Helps support smooth idle, steady acceleration, and good fuel economy
• Uses hot-film sensing technology, which Bosch has long applied in air mass measurement
• Built to meet original equipment quality standards for dependable, long-lasting performance
• Designed for direct replacement of a worn or contaminated sensor

Why Replace a MAF Sensor:

A failing mass air flow sensor can cause rough idle, hesitation, stalling, poor fuel economy, or a check engine light. Installing a quality replacement helps restore proper engine management and drivability.
