Standard Motor Products MAS0372 Mass Air Flow Sensor MAF

The Standard Motor Products MAS0372 is a direct-fit, 100% new mass air flow (MAF) sensor engineered to restore accurate airflow measurement and reliable engine performance. Unlike remanufactured alternatives, this sensor is never rebuilt from used cores, eliminating the risk of leftover debris contamination that can lead to premature sensor failure.

Key Features:

• 100% New Construction — Never remanufactured, ensuring no residual debris or contamination from prior use
• OE-Matched Airflow Calibration — Factory-calibrated to deliver precise airflow readings that the Engine Control Module (ECM) requires for correct air/fuel ratio management
• Platinum RTD Sensing Element — Custom-designed platinum Resistance Temperature Detector (RTD) sensor for highly accurate and stable output signals
• Upgraded Construction — Features thicker walls and enhanced internal components for improved durability over standard replacement parts
• Extensive Testing — Computer-tested and subjected to rigorous durability and environmental testing to ensure performance under demanding real-world conditions
• Direct Fit — Designed as a drop-in replacement to OE specifications for a straightforward installation

A failing mass air flow sensor can trigger symptoms such as rough idle, poor acceleration, reduced fuel economy, engine stalling, and an illuminated check engine light. Replacing a worn or faulty MAF sensor with the MAS0372 restores proper communication between the intake airflow and the ECM, supporting clean combustion and optimal engine efficiency.
