Bosch 0280218340 Hot-Film Mass Air Flow Sensor

The Bosch 0280218340 is a premium-grade hot-film air mass meter (MAF sensor) engineered to OEM standards for precise engine management. This sensor utilizes advanced hot-film technology to accurately measure the mass of air entering the engine, providing critical data to the engine control unit (ECU) for optimal fuel injection timing and air-fuel ratio control.

Key Features:

• Hot-film technology measures air mass independently of temperature and density
• Precision sensor membrane with integrated digital signal processing
• Compact, lightweight design simplifies installation
• Durable housing built to withstand harsh environmental conditions and extreme temperatures
• Direct replacement for OEM part number 06A906461L
• Engineered specifically for Audi and Volkswagen applications

The sensor operates by measuring temperature differences across a heated membrane as intake air flows over it. An integrated electronic module calculates the air mass from these measurements and transmits accurate data to the ECU, enabling precise fuel metering for improved performance, fuel efficiency, and reduced emissions. Backed by Bosch's reputation for quality and reliability, this mass air flow sensor helps restore peak engine performance and smooth operation.
