Standard Motor Products MAS0287 Mass Air Flow Sensor MAF

The Standard Motor Products MAS0287 is a direct-fit, 100% new Mass Air Flow (MAF) sensor engineered to restore precise airflow measurement and reliable engine management performance. Unlike remanufactured alternatives, this sensor is never rebuilt from used components, eliminating the risk of residual debris that can disrupt ECM communication and cause drivability problems.

Key Features:

• 100% New Construction — never remanufactured, ensuring a clean, debris-free sensing element from day one
• Custom-Designed Platinum RTD Sensor — precisely matches OE airflow and temperature outputs for accurate ECM readings
• Airflow-Calibrated — every unit is calibrated to deliver accurate airflow readings under demanding engine conditions
• Thicker Walls and Upgraded Components — built to meet or exceed OE structural standards and withstand extreme vibration
• OE-Quality Signal Output — communicates accurately with the Engine Control Module (ECM) to maintain proper air/fuel ratio, fuel economy, and power
• Rigorously Tested — subjected to choked airflow, salt and chemical contamination, and on-vehicle road and vibration testing

The MAS0287 mass airflow sensor is a precision replacement component that plugs directly into the vehicle's intake air stream, measuring the volume and density of air entering the intake manifold. This data is relayed to the ECM to calculate the correct fuel injection quantity for clean, efficient combustion. Replacing a faulty MAF sensor can resolve symptoms such as poor idle, rough running, hesitation, reduced fuel economy, and illuminated check engine lights related to MAF fault codes.
