Holstein Mass Air Flow Sensor

The Holstein Mass Air Flow (MAF) Sensor line offers direct-fit replacement air mass sensors. They measure the amount of air entering the engine and send that data to the engine control module (ECM/ECU). The ECM uses it to calculate fuel delivery and air-fuel ratio, which helps with engine performance, fuel efficiency, and emissions control.

Key Features:

• Direct-fit replacement for worn or failed OE mass air flow sensors
• Engineered to meet or exceed original equipment specifications
• Hot-wire or hot-film sensing element for accurate airflow measurement
• Supplies the data the engine management system needs for fuel injection and ignition timing
• Quality-tested for reliable operation and long service life
• OE-style electrical connectors for secure connections

A failing MAF sensor can cause rough idle, hesitation, poor acceleration, reduced fuel economy, and a check engine light. Replacing it with a Holstein sensor helps restore smooth, efficient engine operation. Holstein Parts supplies replacement sensors and engine management components for professional technicians and DIY installers. Choose the child item that matches your application.
