Hella 358166121 Mass Air Flow Sensor

The Hella 358166121 Mass Air Flow (MAF) Sensor is a precision-engineered component designed to accurately measure the volume and density of air entering the engine intake system. This sensor plays a critical role in engine management by providing real-time data to the vehicle's electronic control unit (ECU), enabling optimal fuel delivery and combustion efficiency.

Key Features:

• Direct-fit replacement sensor designed to meet or exceed OEM specifications
• Hot-wire or hot-film sensing element for precise air mass measurement
• Engineered to withstand harsh underhood temperatures and contaminants
• Provides accurate signals across all engine operating conditions
• Helps maintain proper air-fuel ratio for optimal performance and emissions
• Quality construction from Hella, a trusted OEM supplier to major automotive manufacturers

Mass air flow sensors are essential for modern fuel-injected engines, ensuring proper engine performance, fuel economy, and emissions control. A failing MAF sensor can cause poor acceleration, rough idle, decreased fuel economy, or illuminated check engine lights. This Hella sensor delivers reliable performance and precise measurements to keep your engine running at peak efficiency.
