Bosch 997-606-125-01 Mass Air Flow Sensor MAF

The Bosch 997-606-125-01 is a high-precision mass air flow (MAF) sensor designed to accurately measure the volume of air entering the engine. This critical sensor provides real-time data to the engine control unit (ECU) to calculate the optimal air-fuel ratio for efficient combustion and performance.

Key Features:

• Genuine Bosch OEM quality sensor with precise platinum wire or thick film ceramic measuring elements
• Bosch part number 0-280-218-09F (0280218-09F / 028021809F)
• Hot-film air mass sensor technology for accurate, density-independent measurements
• Direct replacement for OEM specifications ensuring proper fitment and function
• Integrated ambient temperature sensor for enhanced accuracy

Symptoms of a Failing MAF Sensor:

• Rough idle or engine hesitation
• Poor fuel economy and increased emissions
• Black smoke from exhaust
• Reduced acceleration or engine surging
• Hard starting or check engine light illumination

A properly functioning mass air flow sensor is essential for maintaining optimal engine performance and preventing excessive fuel consumption that can lead to cylinder wear. Regular inspection and replacement every 60,000-90,000 miles is recommended for peak performance.
