Holstein 2MAF0142 Mass Air Flow (MAF) Sensor

The Holstein 2MAF0142 is a direct-fit, 100% new Mass Air Flow (MAF) Sensor engineered to meet or exceed original equipment (OE) specifications. Designed as a plug-and-play replacement, this sensor restores accurate air mass measurement to the engine's intake system, helping the ECU (Engine Control Unit) precisely control fuel delivery for optimal combustion efficiency, throttle response, and emissions compliance.

Unlike remanufactured units, the Holstein 2MAF0142 is built entirely new from the ground up, ensuring consistent performance and long-term reliability from day one. Hot wire sensing technology detects both the volume and density of incoming air and transmits that data to the vehicle's engine management system in real time.

Key Features:

• 100% new construction — never remanufactured or rebuilt
• Meets or exceeds OE specifications for accurate, reliable airflow measurement
• Hot wire sensing element for fast, precise air mass detection
• Direct plug-and-play fitment — no modification required
• Backed by Holstein's 3-year / 36,000-mile warranty
• Restores proper fuel trim, idle quality, and throttle response
• Helps eliminate MAF-related diagnostic trouble codes (DTCs)

A failed or contaminated MAF sensor can cause rough idle, poor fuel economy, hesitation, and check engine lights. Replacing it with the Holstein 2MAF0142 returns the engine management system to factory-level accuracy, supporting smooth operation across all RPM ranges.
