Hella 009142021 Mass Air Flow Sensor OE Replacement

The Hella 009142021 is a direct-fit OE-quality mass air flow (MAF) sensor engineered to restore precise air measurement and optimal engine performance. Manufactured by Hella — a globally recognized OEM supplier of automotive electronics — this replacement MAF sensor is built to meet original equipment standards in fit, form, and function.

What It Does:

The mass air flow sensor measures the volume and density of air entering the engine. The engine control module (ECM) uses this data to calculate the correct fuel delivery for efficient combustion, maximizing engine power and fuel economy. A failed or degraded MAF sensor can cause rough idling, stalling, poor fuel economy, and an illuminated check engine light.

Key Features:

• OE-Quality Construction: Built to meet or exceed original equipment specifications for consistent, dependable performance
• High Measurement Precision: Advanced sensing technology delivers accurate air mass readings across the full operating range
• Direct Fit Replacement: Engineered for seamless plug-and-play installation with no modification required
• Durable Design: Robust construction withstands heat, vibration, and contaminants for a long service life
• OEM Cross-References: Replaces OEM part numbers including 13621432356 (BMW) and 2816437100 / 0K55813210 (Hyundai/Kia)

About Hella:

Hella is a German-engineered automotive supplier with over 120 years of experience developing electronics and lighting systems as a Tier-1 OEM partner to leading automakers worldwide. Their aftermarket parts leverage the same OE engineering expertise used in original production vehicles.

Professional installation is recommended. Always replace a faulty MAF sensor rather than attempting to clean it, as cleaning solvents can damage sensor insulation and lead to premature failure.
