Motorad 3MF174 Mass Air Flow Sensor With Housing Assembly

The Motorad 3MF174 is a direct-fit mass air flow (MAF) sensor with housing assembly, engineered to accurately measure the volume and density of air entering the engine and relay that data to the engine control unit (ECU). This precise airflow data allows the ECU to calculate and deliver the optimal fuel-to-air mixture, supporting efficient combustion, proper throttle response, and reduced emissions.

Key Features:

• Proprietary NTC Technology matched to OE resistance for the most precise signal to the ECU, resulting in an optimal fuel/air mixture
• Platinum-infused hot wire sensor minimizes corrosion and ensures a consistently stable reading over time
• Double wire bonding construction protects against signal degradation and failures caused by engine vibration
• 100% thermal cycle and sonic nozzle tested to verify performance and durability prior to leaving the factory
• Contamination-resistant design engineered to withstand harsh under-hood environments
• Meets or exceeds OEM specifications — manufactured at IATF 16949-certified facilities
• Limited lifetime warranty backed by Motorad
