Airtex 5S2728 Mass Air Flow Sensor MAF MF21027

The Airtex 5S2728 is a direct-fit, OE-replacement Mass Air Flow (MAF) Sensor, also cross-referenced as MF21027. Designed to restore accurate airflow measurement and proper engine management, this sensor is engineered to meet or exceed original equipment specifications for a precise, reliable fit.

The MAF sensor monitors the volume and density of air entering the engine and transmits this data to the Engine Control Unit (ECU). The ECU uses this signal to calculate the correct air-fuel mixture, ensuring optimal combustion efficiency, fuel economy, and emissions performance. A faulty or failing MAF sensor can cause rough idle, poor acceleration, increased fuel consumption, and illuminate the Check Engine light.

Key Features:

• Direct OEM replacement — engineered to match original equipment specifications
• Restores proper air-fuel ratio calibration and engine performance
• Helps eliminate rough idle, hesitation, and poor fuel economy associated with MAF sensor failure
• Plug-and-play installation with no modifications required
• Cross-references: MF21027
• Manufactured by Airtex Automotive Division, a trusted name in OE-replacement sensors and fuel system components

The Airtex 5S2728 MAF sensor is built for durability and long service life, making it an ideal choice for professional technicians and DIY mechanics seeking a reliable, cost-effective replacement solution.
