Bosch Mass Air Flow Sensor

The Bosch Mass Air Flow Sensor (MAF sensor, also called an air mass meter) measures the volume and density of air entering the engine. It sends that data to the engine control unit (ECU). The ECU uses the signal to calculate the correct fuel delivery for efficient combustion, smooth running and responsive performance.

Key Features:

• Accurately measures intake airflow so the ECU can maintain the proper air-fuel ratio
• Hot-film sensing technology for fast, precise response across operating conditions
• Built to meet original equipment specifications for fit, function and reliability
• Designed for durability against heat, vibration and the under-hood environment
• Helps support fuel economy, emissions control and drivability

A failing mass air flow sensor can cause rough idle, hesitation, poor fuel economy, stalling or a check engine light. Replacing it with a Bosch sensor helps restore proper engine management. Bosch is a long-time original equipment supplier to automakers worldwide, and its aftermarket parts are built to the same quality standards.
