Hella 009149491 Mass Air Flow Sensor MAF OE-Quality Replacement

The Hella 009149491 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 MAF sensor continuously measures the volume and density of air entering the engine, allowing the engine control unit (ECU) to calculate and deliver the precise fuel quantity needed for optimal combustion.

Built on Hella's deep OE manufacturing expertise, this sensor features hot-film sensor technology for high air-mass measuring precision, ensuring accurate fuel-to-air ratio control. A properly functioning MAF sensor is critical to maintaining engine power, fuel economy, throttle response, and emissions compliance. A faulty or degraded sensor can cause rough idle, reduced performance, increased fuel consumption, and potential damage to related emission components such as the EGR valve and particulate filter.

Key Features:

• Manufactured to OE specifications for precise fit and reliable performance
• Hot-film sensor technology delivers high air-mass measurement accuracy
• Supports stable combustion efficiency and proper exhaust emissions management
• Robust construction designed for long service life in varied operating conditions
• Direct OEM-style connector for straightforward installation
• Backed by Hella's OE engineering know-how as part of Forvia, the world's seventh-largest automotive supplier

Hella recommends replacing a dirty or faulty MAF sensor rather than cleaning it to ensure reliable long-term results. Professional installation is advised. Always consult your vehicle manufacturer's service manual before replacing this component.
