Standard Motor Products MAS0274 Mass Air Flow Sensor MAF

The Standard Motor Products MAS0274 is a direct-fit replacement Mass Air Flow (MAF) sensor engineered to restore accurate airflow measurement and proper engine management. Built 100% new — never remanufactured — it eliminates the risk of leftover debris that can cause premature sensor failure.

Key Features:

• 100% New Construction: Never remanufactured, ensuring a clean, debris-free sensor right out of the box
• Custom Platinum RTD Sensing Element: Precisely matches OE airflow and temperature outputs for accurate ECU communication
• 100% Computer-Tested: Each sensor is validated to deliver accurate airflow readings under demanding engine conditions
• Correct Air/Fuel Ratio: Ensures the engine management system can maintain an optimal air/fuel mixture for clean, efficient combustion
• Enhanced Durability: Upgraded components with thicker walls and superior circuit reliability protect against Electro Static Discharge (ESD)
• No Moving Parts: Wear-free sensor design contributes to long service life
• OE-Matched Output: Engineered to precisely match original equipment specifications for seamless plug-and-play installation

The MAS0274 is part of Standard Motor Products' comprehensive MAF sensor lineup, covering more than 90% of all MAF-equipped vehicles. Proper MAF sensor function is critical — a failing sensor can trigger check engine lights, rough idle, poor fuel economy, and hesitation. Restoring accurate airflow data with a quality replacement sensor helps the ECM deliver the right fuel trim for peak engine performance.
