Hella 358166251 Mass Air Flow Sensor MAF

The Hella 358166251 is a direct-fit replacement Mass Air Flow (MAF) sensor engineered to OE specifications. The MAF sensor measures the volume and density of air entering the engine and relays this data to the engine control unit (ECU), enabling precise fuel delivery calculations for optimal combustion efficiency.

Key Features:

• OE-Level Accuracy: Engineered to meet or exceed original equipment specifications for reliable, factory-correct performance
• Hot-Film Sensor Technology: Provides high-precision air mass measurement across a broad dynamic range for accurate fuel-to-air ratio control
• Robust Construction: Built for long service life and consistent performance across diverse operating and environmental conditions
• Direct Replacement: Designed as a plug-and-play replacement for the original MAF sensor — no modification required
• Improved Engine Response: Restores proper throttle response, fuel economy, and idle stability by delivering accurate airflow data to the ECU

Symptoms of a Failing MAF Sensor:

• Rough or unstable idle
• Hesitation or stumble during acceleration
• Reduced fuel economy
• Check engine light with DTCs such as P0100, P0101, P0102, or P0103
