Motorad 3MF257 Mass Air Flow Sensor With Housing Assembly

The Motorad 3MF257 is a direct-fit Mass Air Flow (MAF) Sensor with Housing Assembly, engineered to precisely measure the volume and density of air entering the engine. This data is relayed to the ECU to calculate the correct fuel injection quantity, ensuring optimal combustion efficiency, smooth idle, and responsive throttle performance.

Key Features:

• Proprietary NTC Technology – Matches OE resistance characteristics to deliver the most accurate signal to the ECU, resulting in an optimal air/fuel mixture
• Platinum-Infused Hot Wire Sensor – Resists corrosion and maintains a stable, consistent airflow reading over the life of the sensor
• Double Wire Bonding – Upgraded internal construction protects against signal degradation and failure caused by engine vibration
• Contamination-Resistant Design – Engineered to minimize the accumulation of debris and contaminants that can cause erratic readings or sensor failure
• 100% Tested – Every unit undergoes thermal cycle testing and sonic nozzle flow testing to verify performance and durability before leaving the facility
• OEM-Grade Quality – Designed and manufactured to meet or exceed OEM specifications at IATF 16949-certified facilities
• Complete Assembly – Includes the MAF sensor and housing for a straightforward, plug-and-play installation
• Limited Lifetime Warranty – Backed by Motorad's confidence warranty on all engine management products

The Motorad 3MF257 MAF sensor with housing is the ideal replacement for a failed or contaminated factory mass airflow sensor. A faulty MAF sensor can trigger a check engine light, cause poor fuel economy, rough idling, or hesitation on acceleration — this assembly restores proper engine management and drivability.
