Hitachi Auto Products MAF0120 Mass Air Flow Sensor

The Hitachi Auto Products MAF0120 is a premium mass air flow (MAF) sensor designed to deliver precise air flow measurements for optimal engine performance and fuel efficiency. This genuine OE-quality sensor measures the amount and characteristics of air entering the engine, sending accurate data to the engine control unit (ECU) to calculate the exact fuel-to-air ratio needed for efficient combustion.

Key Features:

• 100% air flow tested for ideal performance and calibrated for each specific application
• Precision sensing elements with glass-coated platinum wire for enhanced durability and rapid response
• Specially designed housing with contaminant bypass port to protect sensing elements from debris
• Protected circuitry and welded connections (not soldered) for increased reliability
• Optimized air passages for accurate readings even with EGR systems
• 8-pin blade terminal connector configuration
• Meets or exceeds OE specifications and strict emission standards

Hitachi's advanced manufacturing process ensures tight error tolerances, preventing engines from running lean or rich due to incorrect air flow data. The sensor's precision elements are designed to provide quick, reliable readings to the ECM for consistent engine performance and reduced emissions. Ideal replacement for GM vehicles including select Buick, Cadillac, Chevrolet, and GMC models.
