Standard Motor Products MAS0366 Mass Air Flow Sensor MAF

The Standard Motor Products MAS0366 is a 100% newly manufactured Mass Air Flow (MAF) sensor designed to deliver precise airflow measurements to your vehicle's Engine Control Unit (ECU). By accurately reporting the volume of air entering the intake, the MAF sensor enables the ECU to calculate and maintain the correct air/fuel ratio for clean, efficient combustion.

Unlike remanufactured alternatives, this sensor is built entirely from new components, eliminating the risk of leftover debris contamination that can compromise sensor accuracy and lead to premature failure. Manufactured in Germany and calibrated to extremely tight OE specifications, the MAS0366 is engineered to restore factory-level engine performance right out of the box.

Key Features:

• 100% New Construction – No remanufactured parts; zero risk of debris-related sensor failure
• OE-Calibrated Accuracy – Manufactured to tight OE tolerances for precise airflow output under all operating conditions
• Custom Platinum RTD Sensing Element – Upgraded sensing technology for superior accuracy and durability
• Made in Germany – Built to exacting quality standards
• Direct-Fit Replacement – Engineered for a drop-in installation with no modifications required
• Computer-Tested – Each unit is tested to ensure accurate ECU communication under demanding conditions

A failing MAF sensor can trigger check engine lights, cause rough idling, poor acceleration, and reduced fuel economy. Replacing it with a precision-built unit like the MAS0366 restores proper engine management and helps prevent long-term drivetrain issues.
