Motorad 1MF442 Mass Air Flow Sensor OE Replacement

The Motorad 1MF442 is a direct-fit OE replacement mass air flow (MAF) sensor engineered to precisely measure the volume of air entering the engine and relay that data to the engine control unit (ECU). Accurate airflow measurement is critical for proper fuel trim, smooth idle, and efficient combustion — making a quality MAF sensor essential to overall engine performance.

Key Features:

• Proprietary NTC Technology — matches OE resistance values to deliver the most precise signal to the ECU, supporting an optimal air/fuel mixture
• Platinum-infused hot wire sensor — resists corrosion and maintains consistent, stable readings over the life of the sensor
• Double wire bonding construction — added durability against vibration-induced signal failures
• Contamination-resistant design — engineered to minimize the effects of dirt, oil, and debris on sensor accuracy
• 100% thermal cycle and sonic nozzle tested — every unit is tested prior to shipment to ensure reliable, worry-free performance
• Meets or exceeds OEM specifications — manufactured at IATF 16949-certified facilities to the same standards as original equipment
• Limited lifetime warranty — backed by Motorad's confidence in their engine management product line
