How the 3MF429 Works

The MotoRad 3MF429 is a replacement MAF sensor that helps the engine management system calculate airflow entering the intake stream. Accurate airflow data supports proper fuel combustion, smoother drivability, and consistent engine response. This part cross-references Hyundai/Kia OE number 281643C100 for the same application.

What This Sensor Helps Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or stumble during acceleration
• Check engine lights related to mass air flow sensor performance
• Poor fuel metering from a worn or contaminated sensor
• Driveability issues on Hyundai Genesis, Sonata, Veracruz, and Kia Sedona, Optima, and Sorento models

Installation Notes

Verify connector style, terminal count, and vehicle application before installation. The 3MF429 uses a female connector with blade terminals and does not include mounting hardware or a bracket. Clean the intake tract and inspect the air filter housing before installing the new sensor to help prevent contamination from entering the replacement unit.
