Hella 358166271 Mass Air Flow Sensor MAF

The Hella 358166271 is a direct-replacement mass air flow (MAF) sensor engineered to OE specifications. Located between the air filter housing and the intake manifold, the MAF sensor continuously measures the volume and density of air entering the engine, providing real-time data to the engine control unit (ECU) for precise air/fuel mixture calibration.

Key Features:

• Direct OEM-quality replacement for a precise drop-in fit
• Measures intake air mass for accurate fuel delivery calculations
• Supports proper EGR system functionality as a control gateway
• Engineered to maintain functional accuracy throughout the full product lifespan
• Manufactured by Hella, a globally recognized OE supplier to major vehicle brands
• Helps restore proper engine performance, fuel efficiency, and emissions compliance

A failing MAF sensor can cause symptoms including rough idle, loss of power, poor fuel economy, increased emissions, and illuminated check engine lights. Replacing a worn or contaminated sensor with the Hella 358166271 restores accurate air mass readings and helps protect related engine management and emissions components from cascading faults.
