Hella 358095841 Mass Air Flow Sensor Bolted/Bayonet Mount Without Housing

The Hella 358095841 is a replacement mass air flow (MAF) sensor designed for direct installation into a vehicle's original air intake housing. This sensor-only unit uses a bolted/bayonet mounting style and ships without an external housing, making it an ideal solution for vehicles where the original housing is in serviceable condition and only the sensing element requires replacement.

How It Works:

The mass air flow sensor is positioned between the air filter housing and the intake manifold. It continuously measures the volume and density of air entering the engine and transmits this data to the engine control unit (ECU), which uses it to calculate the precise fuel injection quantity needed for optimal combustion. This real-time measurement directly affects throttle response, fuel efficiency, and exhaust emissions.

Key Features:

• Hot-film sensor technology for high air-mass measuring precision
• Bolted/bayonet mounting — installs directly into the OEM air intake housing
• Without housing — sensor element only; retains the vehicle's original intake housing
• Engineered to OEM quality standards, drawing on Hella's original equipment manufacturing expertise
• Consistent performance across a broad dynamic measurement range
• Supports accurate exhaust gas recirculation (EGR) system control
• Built for long service life with robust sensor construction

Symptoms of a Failing MAF Sensor:

• Poor fuel economy or rough idle
• Hesitation or stumbling during acceleration
• Engine stalling or hard starting
• Check engine light with DTCs such as P0101, P0102, or P0103
• Increased exhaust emissions
