Hitachi Auto Products MAF0027 Mass Air Flow Sensor

The Hitachi MAF0027 Mass Air Flow Sensor is engineered to deliver precise air flow measurement for optimal engine performance and fuel efficiency. This OE-quality sensor detects the amount of air entering the engine and transmits accurate data to the engine control unit (ECU) to calculate the proper air-to-fuel ratio, ensuring smooth operation and reduced emissions.

Key Features:

• Platinum wire sensing element responds rapidly to changes in air flow for enhanced engine efficiency
• Glass film coating protects the sensing element from contaminants and reinforces reliability
• Integrated induction air temperature sensor for maximum measurement accuracy
• Contaminant bypass ports allow moisture and impurities to exit the housing, reducing sensor contamination
• Welded connections instead of soldering for increased dependability and durability
• Manufactured to tolerances that meet or exceed OE specifications
• 100% air flow tested and calibrated for each specific application

As a Tier 1 OE supplier, Hitachi Astemo produces premium automotive sensors with rigorous quality control and precision manufacturing. This mass air flow sensor features heat and wear resistance, anti-corrosion properties, and is built to strict emissions regulatory standards for both reliability and longevity.
