Bosch Mass Air Flow Sensor MAF Hot Film Technology

Bosch Mass Air Flow (MAF) sensors with hot film technology measure the amount of air entering the engine so the engine control unit can calculate the correct fuel delivery. Also called an air mass meter or MAF sensor, this component helps support smooth idle, responsive acceleration, efficient fuel use and low emissions.

Key Features:

• Hot film sensing element: Measures intake air mass directly, which gives the engine management system accurate input across operating conditions.
• Fast response: Reacts quickly to changes in airflow so the ECU can adjust the fuel mixture as needed.
• Integrated electronics: Converts the airflow measurement into a signal the engine control unit can use.
• Bosch quality: Bosch is a leading OE supplier of engine management components. Its sensors are built to meet demanding durability and accuracy requirements.

A worn or contaminated MAF sensor can cause rough idle, hesitation, poor fuel economy, stalling or a check engine light. Replacing it with a quality Bosch sensor helps restore proper air metering and engine performance. Select the variant that matches your application by its individual part number.
