ACDelco GM Genuine Parts Mass Air Flow Sensor

The ACDelco GM Genuine Parts Mass Air Flow Sensor (MAF sensor) measures the volume and density of air entering the engine. It sends this data to the engine control module (ECM/PCM). The module uses the signal to calculate fuel delivery and ignition timing, which helps the engine run efficiently and respond smoothly.

Key Features:

• Genuine GM Parts engineering from ACDelco, GM's original equipment parts brand
• Gives the engine computer accurate airflow readings for proper air-fuel mixture control
• Helps maintain fuel economy, throttle response, and emissions performance
• Built to meet original equipment specifications for fit, function, and durability
• Replaces a worn, contaminated, or failed MAF sensor, which can cause rough idle, hesitation, stalling, poor fuel economy, or a check engine light

A new mass air flow sensor can help restore factory-level engine performance and drivability. Choose the specific part number that matches your application from the available options in this product line.
