Hella 358166281 Mass Air Flow Sensor MAF

The Hella 358166281 is a direct-fit replacement mass air flow (MAF) sensor engineered to OEM quality standards. Positioned between the air filter housing and the intake manifold, the mass air flow sensor measures the volume and density of incoming air, providing critical real-time data to the engine control unit for precise air/fuel mixture adjustment and optimal combustion efficiency.

Key Features:

• OEM-Level Quality: Manufactured with Hella's original equipment expertise, ensuring precise fit and reliable performance that meets or exceeds factory specifications
• High Measurement Accuracy: Advanced hot-film sensing technology delivers consistent, precise airflow readings for optimized fuel injection and engine management
• EGR System Compatibility: Functions as a control reference for the exhaust gas recirculation (EGR) system, supporting emissions compliance
• Durable Construction: Built for long service life under varied operating conditions, maintaining consistent output over time
• Direct Plug-In Fitment: Designed as a drop-in replacement using the vehicle's original housing and connector — no modification required

A failing mass air flow sensor can trigger diagnostic trouble codes such as P0100, P0101, P0102, or P0103, and may cause symptoms including rough idle, engine stalling, reduced acceleration, poor fuel economy, and increased emissions. Hella recommends replacing a dirty or defective MAF sensor rather than attempting to clean it, for a reliable long-term repair.
