Motorad 1MF238 Mass Air Flow Sensor | OEM-Spec MAF Replacement

The Motorad 1MF238 is a direct-fit 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 MAF sensor readings are critical for calculating the correct fuel injection quantity, supporting optimal combustion efficiency, fuel economy, and reduced emissions.

Key Features:

• Proprietary NTC Technology — Matches OE resistance for the most precise signal to the ECU, resulting in an optimal fuel-to-air mixture
• Platinum-infused hot wire element — Minimizes corrosion and ensures a stable, consistent reading over the life of the sensor
• Double wire bonding — Upgraded construction protects against signal degradation and failure caused by engine vibration
• Contamination-resistant design — Engineered to reduce particulate buildup that can skew airflow readings
• 100% tested — Every unit undergoes thermal cycle and sonic nozzle testing to verify performance and durability before leaving the factory
• Meets or exceeds OEM specifications — Manufactured at IATF 16949-certified facilities for consistent quality control
• Limited lifetime warranty — Backed by Motorad's confidence guarantee on all engine management products

The Motorad 1MF238 MAF sensor installs as a direct OEM replacement, restoring factory-accurate airflow measurement without the need for additional calibration. It is an ideal solution for resolving symptoms such as rough idle, poor fuel economy, hesitation under acceleration, or a stored mass air flow sensor fault code.
