Hella 7.22184.25.0 Pierburg OEM Air Mass Flow Sensor (MAF)

The Hella 7.22184.25.0 is a Pierburg OEM-quality Mass Air Flow (MAF) sensor, also known as an air mass sensor or air flow meter, engineered to meet original equipment manufacturer specifications. Manufactured under Hella's Pierburg brand, this sensor is built to the same standards as the factory-installed component it replaces.

The mass air flow sensor measures the volume and density of air entering the engine's intake system. This data is relayed to the engine control unit (ECU), which uses it to calculate the precise air-fuel mixture needed for optimal combustion, engine efficiency, and emissions compliance.

Key Features:

• Pierburg OEM-quality construction — meets or exceeds original equipment specifications
• Precise air mass measurement for accurate ECU fuel-trim calculations
• Supports proper engine performance, fuel economy, and emissions control
• Direct-fit replacement designed for straightforward installation
• Manufactured by Hella, a globally recognized Tier 1 automotive supplier

A failing or contaminated MAF sensor can cause rough idling, poor fuel economy, hesitation, or a check engine light. Replacing it with a quality Pierburg unit like the 7.22184.25.0 restores accurate air metering and helps bring engine performance back to factory standards.
