Beck/Arnley 158-1072 Mass Air Flow Sensor - Air Mass Sensor MAF

The Beck/Arnley 158-1072 is a direct-replacement mass air flow (MAF) sensor — also known as an air mass sensor — engineered to match OE form, fit, and function for foreign nameplate vehicles. The MAF sensor is a critical engine management component that measures the volume and density of air entering the intake, providing real-time data to the engine control unit (ECU) for precise fuel delivery and ignition timing.

Key Features:

• Matches original equipment specifications for form, fit, and function
• Built to withstand the demands of the engine environment
• Features corrosion-resistant terminals and protective coatings for long-term durability
• May come with or without housing depending on original equipment design
• Application-specific design for foreign nameplate vehicles — no modifications required
• Sourced through Beck/Arnley's global network of quality-vetted suppliers

A faulty or failing mass air flow sensor can trigger check engine lights, cause rough idle, reduce fuel economy, and lead to poor overall engine performance. The Beck/Arnley 158-1072 restores accurate airflow readings to the ECU, helping return the engine to peak efficiency. Beck/Arnley's product specialists validate each part against OE standards so you can install with confidence.
