Bosch Hot Film Air Mass Meter Sensor

The Bosch Hot Film Air Mass Meter Sensor, also called a mass air flow (MAF) sensor or MAF 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. This helps the engine run efficiently, produce steady power, and keep emissions low.

Key Features:

• Hot film measuring technology: A heated sensing element gives an accurate electronic reading of intake air mass.
• Quick response: The sensor reacts fast to changes in airflow. This supports smooth throttle response and stable idle.
• Engineered for OE-level performance: Bosch is a leading original equipment supplier, and its air mass meters are built to meet demanding automotive standards.
• Durable construction: The housing and electronics are designed to withstand engine bay heat, vibration, and long service life.
• Plug-and-play replacement: Each sensor is made to replace the original unit. Installation is usually simple.

A failing air mass sensor can cause rough idle, hesitation, poor fuel economy, stalling, or a check engine light. Replacing it with a Bosch hot film air mass meter can help restore proper engine management and drivability. Choose the correct part number for your application.
