Hella 358166021 Mass Air Flow Sensor (MAF) OE Replacement

The Hella 358166021 is a direct-replacement mass air flow (MAF) sensor engineered to meet or exceed original equipment specifications. The MAF sensor plays a critical role in engine management by precisely measuring the volume and density of air entering the intake, allowing the engine control unit (ECU) to calculate the correct fuel delivery for optimal combustion efficiency.

Key Features:

• OE-Level Quality: Manufactured to original equipment standards using Hella's proven sensor technology
• Hot-Wire Sensing Element: Delivers high flow measurement accuracy for responsive and reliable air mass readings
• Direct Fit Design: Engineered as a plug-and-play replacement requiring no modification for proper installation
• Durable Construction: Built to withstand the demands of long-term engine bay exposure and operating conditions
• Improved Engine Performance: Accurate air mass data supports optimal fuel injection, throttle response, and emissions control

A failing mass air flow sensor can trigger diagnostic trouble codes such as P0100, P0101, P0102, or P0103, and may cause symptoms including rough idle, poor fuel economy, hesitation under acceleration, or engine stalling. The Hella 358166021 restores factory-correct sensor function to resolve these issues.

Hella is a globally recognized OEM supplier with extensive expertise in automotive electronics and sensor technology, making this MAF sensor a trusted choice for professional technicians and experienced DIYers alike.
