Wells 5S2973 Mass Air Flow Sensor

The Wells 5S2973 Mass Air Flow Sensor is a direct-fit replacement component designed to restore proper engine management function in your vehicle. This sensor plays a critical role in measuring the amount of air entering the engine and transmitting that data to the Engine Control Module (ECM), which uses the information to calculate the precise fuel delivery needed for optimal combustion efficiency.

Key Features:

• Engineered and manufactured by Wells Vehicle Electronics, a trusted name with over 120 years of automotive electronics expertise
• Direct replacement design ensures proper fit and reliable performance
• Meets or exceeds OEM specifications for quality and durability
• Hot wire sensor technology provides accurate airflow measurement across varying conditions
• Helps maintain proper air-fuel ratio for optimal engine performance, fuel economy, and emissions control

Mass air flow sensors are essential engine management components that compensate for variations in altitude, temperature, and humidity to ensure the ECM receives accurate data about incoming air volume and density. A properly functioning MAF sensor helps prevent common drivability issues such as rough idling, hesitation, poor acceleration, and reduced fuel economy. The Wells 5S2973 provides reliable performance backed by Wells' commitment to manufacturing professional-grade vehicle electronics that eliminate known OEM design weaknesses.
