Standard Motor Products MF20040 Mass Air Flow MAF Sensor

The Standard Motor Products MF20040 Mass Air Flow (MAF) Sensor is a 100% new, never remanufactured precision component designed to measure the amount of air entering the intake manifold and communicate this critical data to the Engine Control Module (ECM). This sensor plays a vital role in achieving the proper air/fuel ratio for optimal engine performance, fuel economy, and reduced emissions.

Key Features:

• 100% new construction with no leftover debris that can cause sensor failure
• Custom-designed platinum flow RTD sensors that precisely match OE outputs
• Temperature RTD sensors engineered to match OE specifications more closely than competitor diodes
• Computer-tested to ensure accurate airflow readings under all engine conditions
• Hybrid electronic circuitry provides reliable, wear-free sensor life
• Thicker walls and upgraded components for enhanced durability
• Exceeds aftermarket competition in pull strength of RTD lead joints
• Manufactured at IATF 16949 and ISO 14001-certified facilities

Standard Motor Products MAF sensors undergo rigorous choked airflow testing and calibration, salt and chemical contamination testing, and on-vehicle road and vibration testing to ensure they perform flawlessly under all operating conditions. The platinum RTD sensor design resists breakdown under extreme vibration and outperforms competitors in vehicle road testing, air flow testing, and high-temperature degradation scenarios.
