Holstein Mass Air Flow Sensor Assembly

The Holstein Mass Air Flow Sensor Assembly (MAF sensor) is a direct-fit replacement for a worn or failed original air flow sensor. It measures the amount of air entering the engine and sends that data to the engine control unit (ECU). The ECU uses it to calculate air-fuel ratio, so the sensor helps with engine performance, fuel economy and emissions control.

Key Features:

• Direct-fit replacement designed to match the original equipment part
• Full assembly format for straightforward service replacement
• Aftermarket design intended to meet or exceed OE specifications
• Supplies air flow data used for fuel delivery and ignition timing
• Electrical connector for plug-and-play installation

Common Reasons to Replace:

• Rough idle or hesitation
• Inaccurate air metering that affects fuel delivery
• Check engine light from the air flow sensor circuit
• Sensor contamination or wear
