Bosch Hot Film Mass Air Flow Sensor

The Bosch Hot Film Mass Air Flow Sensor (also called a MAF sensor or air mass meter) measures the amount of air entering the engine so the engine control unit can calculate the right fuel delivery. Accurate airflow readings support smooth idle, responsive acceleration, good fuel economy and controlled emissions.

Key Features:

• Hot film sensing technology that measures intake air mass directly
• Fast response to changes in airflow for consistent engine management
• Built to meet or exceed original equipment requirements for fit, form and function
• Durable housing and electronics designed to withstand underhood heat, vibration and contaminants
• Backed by Bosch's long history as an original equipment supplier to automakers worldwide

A failing mass air flow sensor can cause symptoms such as rough idle, hesitation, stalling, poor fuel economy or a check engine light. Replacing it with a quality Bosch sensor helps restore proper engine performance and driveability. Select the child item that matches your application for the correct part number.
