Hella 358166351 Mass Air Flow Sensor (MAF) - Direct OE Replacement

The Hella 358166351 is a direct-fit replacement Mass Air Flow (MAF) Sensor engineered to restore precise intake air measurement and proper engine management. Located between the air filter housing and the intake manifold, the MAF sensor continuously monitors the volume and density of air entering the engine, enabling the ECU to calculate and deliver the correct fuel-to-air mixture in real time.

Hella draws on its deep OE manufacturing expertise to produce aftermarket sensors that meet original equipment standards for fit, form, and function. This sensor features hot-film sensing technology for high air-mass measuring precision, supporting stable combustion, optimized fuel efficiency, and reduced emissions.

Key Features:

• Direct OE replacement — engineered to match original equipment specifications for a precise fit
• Hot-film sensor element delivers high measuring accuracy for reliable air-to-fuel ratio control
• Broad dynamic measurement range supports accurate exhaust gas recirculation (EGR) control
• Robust construction designed for consistent performance across diverse operating and environmental conditions
• Restores proper engine response, fuel economy, and throttle performance
• Manufactured by Hella, a globally recognized OE supplier to major automotive manufacturers

A failing MAF sensor can cause symptoms such as rough idle, hesitation, poor fuel economy, increased emissions, and stored fault codes. Replacing a worn or damaged sensor with a quality Hella unit helps restore engine efficiency and protects related emission and engine management components from downstream effects of inaccurate air mass data.
