Bosch 0280218371 Hot Film Air Mass Meter Sensor

The Bosch 0280218371 is an original equipment quality hot film air mass meter (MAF) sensor designed to accurately measure the mass of air entering the engine's intake system. This precision sensor provides the engine control unit with critical real-time data about intake air mass, enabling optimal fuel injection timing and quantity for efficient combustion and reduced emissions.

Key Features:

• Hot film technology with heated sensor membrane for precise air mass measurement
• Integrated electronic module calculates air mass from temperature differential
• Digital signal processing with ASIC ensures accuracy throughout service life
• Measures air mass based on intake airflow over heated resistors on ceramic substrate
• Less sensitive to contamination compared to hot-wire designs
• Direct replacement for original equipment specifications
• Plug-in sensor design for straightforward installation

Bosch is a global leader in mass airflow sensor technology, manufacturing original equipment sensors for automotive manufacturers worldwide. This sensor helps ensure low emissions levels, improved fuel efficiency, and optimal engine performance. Signs of a failing MAF sensor may include rough idle, increased fuel consumption, poor drivability, or elevated emissions.
