Hella 358095721 Mass Air Flow Sensor Bolted/Bayonet Mount Without Housing

The Hella 358095721 is an OE-quality replacement mass air flow (MAF) sensor featuring a bolted/bayonet mounting style and is supplied without housing. Designed to meet or exceed original equipment specifications, this sensor delivers the precise air mass measurements your engine management system depends on for accurate fuel delivery and stable combustion.

Key Features:

• Bolted/Bayonet Mount: Direct-fit installation using the vehicle's existing housing and mounting points
• Without Housing: Sensor element only — designed to replace the internal sensing element rather than the full assembly
• Hot-Film Sensor Technology: Provides high measuring precision across a broad dynamic range for accurate air-fuel ratio control
• OE-Level Quality: Manufactured to original equipment standards for consistent performance and long service life
• Robust Construction: Built to withstand demanding under-hood temperatures and environmental conditions

A failing mass air flow sensor can trigger diagnostic trouble codes such as P0101, P0102, or P0103 and cause symptoms including rough idle, poor acceleration, reduced fuel economy, and increased emissions. Replacing the sensor with a genuine Hella unit restores accurate airflow measurement and returns engine performance to factory specifications.
