Bosch 0 280 218 09J Hot-Film Air Mass Sensor

The Bosch 0 280 218 09J is a precision hot-film air mass sensor (MAF) designed to measure the exact volume of air entering the engine for optimal fuel combustion and engine performance. As an original equipment manufacturer (OEM) quality component, this sensor provides accurate air mass flow readings to the engine control unit (ECU) to ensure proper air-fuel ratio management.

Key Features:

• Hot-film sensor technology for precise air mass measurement
• Complete sensor and housing assembly, factory calibrated for accurate readings
• OE quality construction ensures proper function and emission compliance
• Micromechanical sensor element design for reliable performance
• High-quality materials with robust design for long service life
• Direct replacement for original equipment specifications

This air mass sensor helps maintain efficient fuel combustion, optimal engine performance, and proper emission levels. The sensor and housing are calibrated together as a complete unit to ensure precise operation throughout the sensor's service life. Symptoms of a failing MAF sensor may include rough idle, increased fuel consumption, poor drivability, and elevated emissions.
