Standard Motor Products MAS0473 Mass Air Flow Sensor MAF

The Standard Motor Products MAS0473 is a direct-fit replacement Mass Air Flow (MAF) sensor engineered to restore precise airflow measurement and reliable communication with your vehicle's Engine Control Module (ECM). Designed as a new — not remanufactured — unit, this sensor delivers the accuracy and durability needed for proper engine management and fuel efficiency.

Key Features:

• New, not remanufactured: Eliminates concerns about debris or wear from prior use that can compromise sensor performance and cause drivability issues
• Airflow-calibrated: Factory-calibrated to ensure accurate airflow measurement across a wide range of operating conditions and ambient temperatures
• Platinum RTD sensing element: Custom-designed proprietary sensing element provides precise airflow output signals to the ECM
• Enhanced construction: Features thicker walls and upgraded internal components for improved durability over standard aftermarket alternatives
• OE-style fit: Designed for a direct plug-and-play installation with no modifications required
• Strict quality standards: Manufactured and validated to meet or exceed original equipment specifications

A failing MAF sensor can trigger a Check Engine light, cause poor fuel economy, rough idling, hesitation under acceleration, or an incorrect air/fuel mixture. The Standard Motor Products MAS0473 restores accurate airflow data to the powertrain control system, helping your engine achieve the optimal air/fuel ratio for maximum efficiency and performance.
