Spectra Premium MA385 Mass Air Flow Sensor with Ceramic Circuit Board

The Spectra Premium MA385 is a fully new mass air flow (MAF) sensor engineered to original equipment (OE) fit, form, and function. Designed and validated by Spectra Premium's Canadian engineering team, this sensor delivers precise airflow measurement to support accurate fuel delivery and stable engine performance.

Key Features:

• Ceramic printed circuit board protected by silica gel coating for superior resistance to under-hood temperature extremes and road vibrations
• All-platinum resistance thermometer sensors for faster signal response and consistent voltage output
• Platinum connector reduces the number of connection points, improving reaction time to changes in airflow
• Eliminates rough-idle problems by providing reliable, stable voltage through the ceramic circuit board design
• Manufactured in a dust-free, controlled environment using precise electronic components and raw materials stored at constant temperature
• Built and tested under ISO 9001 and TS16949 quality management standards covering raw materials, production, final inspection, and shipment
• Each unit undergoes extensive computerized and road testing to verify real-world performance before leaving the facility
• 100% new construction — no remanufactured parts, no core charge required
• Comes as a complete assembly with all necessary accessories for straightforward installation

The MA385 meets or exceeds the performance of the original equipment sensor it replaces, making it a direct drop-in solution for restoring proper engine management function. Connector type is male oval with five spade terminals and a plastic housing.
