Bosch 0 280 218 09B Hot Film Air Mass Meter MAF Sensor

The Bosch 0 280 218 09B is a hot-film air mass (HFM) sensor designed to provide precise measurement of intake air mass for optimal engine performance and fuel efficiency. This sensor measures the engine's air intake independently of air temperatures and density, providing data that forms the basis for metering the amount of fuel injected into the engine.

Key Features:

• Uses heated sensor membrane technology where intake air flows over the sensor, creating temperature differences between measurement fields that are calculated into accurate air mass readings
• Complete unit with sensing elements paired and calibrated with housing on the production line to ensure precise operation
• Features patented design that increases robustness against water and particulate damage while reducing sensor drift
• Ensures low levels of harmful emissions with greater fuel efficiency and improved engine performance
• 100% new sensor, not remanufactured, ensuring highest quality and longest service life

Achieving the right air-fuel ratio ensures that the engine operates efficiently, which in turn reduces emissions. This Bosch OE-quality mass air flow sensor is engineered to deliver the precise calibration and function required for trouble-free operation and emissions compliance. Signs of a failed mass airflow sensor may include rough idle, a rise in fuel consumption, increased harmful emissions, and poor drivability.
