Hitachi Auto Products MAF0139 Mass Air Flow Sensor

The Hitachi MAF0139 is a direct-fit, OE-grade Mass Air Flow (MAF) Sensor engineered to deliver precise air mass measurements to your vehicle's engine control module (ECM). As a genuine OE-equivalent replacement part, it meets the exact tolerances required by the original equipment manufacturer to ensure proper engine operation and emissions compliance.

Key Features:

• OE-Quality Engineering: Designed and manufactured to meet or exceed original equipment specifications for accurate, reliable performance
• Precision Sensing Elements: Advanced, precision-placed hot-wire sensing elements provide fast and accurate airflow readings to the ECM
• Tight Tolerance Operation: Functions within the strict error tolerances required by OE manufacturers, preventing the engine from running lean or rich
• Contaminant-Resistant Design: Housing designed to allow contaminants to exit the airstream before reaching the sensing elements, protecting accuracy and extending sensor life
• 100% Air Flow Tested: Every sensor is flow-tested and application-calibrated to ensure proper performance and emissions compliance
• Integrated IAT Sensor: Incorporates an intake air temperature (IAT) sensor for comprehensive air charge measurement
• Direct Fit Replacement: Plug-and-play installation with no modifications required

Hitachi Astemo (formerly Hitachi Automotive Systems) is a global OE supplier with decades of experience manufacturing precision engine management sensors. The MAF0139 mass air flow sensor is the trusted choice for restoring factory-level engine performance, fuel efficiency, and emissions control.
