Bosch 028021800W Hot-Film Air Mass Meter MAF Sensor

The Bosch 028021800W is a precision-engineered hot-film air mass meter (MAF sensor) designed to deliver accurate airflow measurements for optimal engine performance and emissions control. This OE-quality sensor utilizes advanced hot-film technology to measure intake air mass and transmit critical data to the engine control unit (ECU) for precise fuel injection calibration.

Key Features:

• Hot-film sensor technology provides accurate airflow measurement across extensive operating ranges
• Factory-calibrated with housing to ensure precise operation and emissions compliance
• Integrated electronic module calculates air mass from temperature differential and transmits signal to ECU
• Sealed housing design protects sensitive sensor elements from contamination
• OE-specification construction ensures proper fit and reliable function
• Helps maintain optimal air-fuel ratio for improved fuel efficiency and reduced emissions

This Bosch mass air flow sensor features a heated sensor membrane that measures airflow by detecting temperature changes as air passes over it. The integrated electronics process this data and send accurate readings to the engine management system, enabling precise fuel delivery and ignition timing. As an original equipment manufacturer component, this MAF sensor meets strict OE specifications to ensure trouble-free operation and proper emissions compliance.
