Bosch 13-62-8-658-527 Hot-Film Air Mass Sensor MAF

The Bosch 13-62-8-658-527 is a hot-film air mass sensor (HFM) designed as original equipment for BMW vehicles equipped with N63 engines. This essential component accurately measures the amount of air entering your engine, providing critical data to the engine control unit for optimal fuel delivery and combustion efficiency.

Key Features:

• Complete unit with sensing elements paired and calibrated with the housing on the production line to ensure precise operation
• Integrated electronic module calculates the air mass from temperature difference and transmits the result to the electronic engine control unit
• Weighs approximately 133 grams (0.29 lbs)
• Cross-references with Bosch part number 0280218417

Signs of a failed mass airflow sensor may include rough idle, a rise in fuel consumption, increased harmful emissions, and poor drivability. Replacing a faulty MAF sensor with this OEM Bosch unit restores proper engine performance and fuel economy. This is the original equipment mass air flow sensor used by BMW on the N63 engines found in 550i, 650i, 750i, Alpina B6, Alpina B7, X5, and X6 models.
