Hella 358095821 Mass Air Flow Sensor Bolted/Bayonet Mount Without Housing

The Hella 358095821 is a direct-fit, OE-quality Mass Air Flow (MAF) Sensor featuring a bolted/bayonet mounting style and supplied without housing. This sensor element measures the volume and density of air entering the engine, delivering precise data to the engine control unit (ECU) to maintain optimal fuel-to-air ratios, combustion efficiency, and exhaust emissions control.

Engineered with hot-film sensor technology, the Hella 358095821 offers a broad dynamic measurement range for high air-mass measuring precision across a wide range of operating conditions. Hella's long-standing role as an original equipment supplier means this aftermarket part is built to the same exacting standards as the OEM component it replaces.

Key Features:

• Bolted/bayonet mounting style — designed to install directly into the existing airflow meter housing
• Supplied as a sensor element without housing for targeted replacement
• Hot-film MAF technology for high-precision air mass measurement
• Meets or exceeds OEM specifications for fit, form, and function
• Robust construction engineered for long service life in diverse operating environments
• Supports accurate exhaust gas recirculation (EGR) and fuel trim management
• Professional installation recommended

A failing mass air flow sensor commonly triggers DTCs P0101, P0102, or P0103 and may cause symptoms such as rough idle, poor acceleration, reduced fuel economy, or an illuminated check engine light. Replacing the sensor element with a quality Hella unit restores accurate engine management and helps return the vehicle to peak performance.
