Standard Motor Products MF21287N Blue Streak Mass Air Flow Sensor

The Standard Motor Products MF21287N is a 100% new Blue Streak Mass Air Flow (MAF) Sensor designed to deliver precise airflow measurement and OE-quality performance. Unlike remanufactured alternatives, this sensor features a custom-designed platinum RTD sensing element that accurately measures the amount of air entering the intake manifold and communicates clearly with the Engine Control Module (ECM).

Key Features:

• 100% new construction—never remanufactured, eliminating leftover debris that can cause sensor failure
• Custom-designed platinum RTD sensor provides highly accurate airflow readings under all operating conditions
• Manufactured with upgraded components including thicker walls and improved RTD lead joints
• Undergoes extensive choked airflow testing, salt and chemical contamination testing, and on-vehicle road and vibration testing
• Temperature RTD sensors match OE specifications more closely than competitor diodes
• Designed to withstand extreme vibration without RTD component failure
• Ensures proper air/fuel ratio for optimal engine performance, fuel economy, and reduced emissions

Standard Motor Products manufactures these sensors at their IATF 16949 and ISO 14001-certified facility with onsite engineering, design, and test labs to guarantee precise OE output matching. This sensor is engineered to outperform remanufactured and lower-quality aftermarket alternatives in vehicle road testing, airflow accuracy, and high-temperature degradation resistance.
