Beck/Arnley 158-1811 Air Mass Sensor – OE Replacement Mass Air Flow Sensor

The Beck/Arnley 158-1811 Air Mass Sensor is a direct-fit OE replacement mass air flow (MAF) sensor engineered to restore proper engine management and fuel delivery performance. Designed specifically for foreign nameplate vehicles, this sensor meets original equipment specifications for form, fit, and function.

The mass air flow sensor — also commonly called an air mass sensor or MAF sensor — measures the volume and density of air entering the engine and sends that data to the ECU. A failing MAF sensor can cause rough idle, poor fuel economy, hesitation under acceleration, or a check engine light. Replacing it with an OE-quality unit like this Beck/Arnley part restores accurate air metering and proper engine operation.

Key Features:

• Matches OE form, fit, and function for a precise, trouble-free installation
• Constructed to withstand the harsh conditions of an engine environment
• Features corrosion-resistant terminals and protective coatings for long-term durability
• May be supplied with or without housing depending on original equipment design
• Sourced through Beck/Arnley's global network of vetted OE-quality suppliers
• Application-specific design ensures accurate air mass measurement for your vehicle
