This is a Genuine OEM Fuel Filter, identified by the Hyundai/Kia MOBIS part number 31112-A70A0. This filter is a factory-original component designed for the fuel pump assemblies of Hyundai and Kia vehicles built on the modern compact platform, featuring the 1.6L and 1.8L Gasoline Direct Injection (GDI) and Multi-Port Injection (MPI) engines.
The filter's function is critical, especially in high-pressure GDI systems:
GDI Protection: The small, highly precise injectors used in GDI engines are extremely susceptible to clogging and damage from fuel contaminants. This in-tank filter ensures the fuel is meticulously cleaned before it reaches the high-pressure fuel pump and the injectors.
Pressure Integrity: As it is integrated with the fuel pump module (and often includes the pressure regulator), using the Genuine MOBIS Part is essential. It guarantees the correct sealing, flow rate, and pressure stability required by the Engine Control Unit (ECU) for reliable starting and maximum engine efficiency.
Cross-Platform Consistency: The commonality of the 31112-A70A0 part number across the Elantra MD, Veloster, and K3 (Cerato) highlights the shared engineering and fuel system architecture between these popular models.
Fitment Assurance: The part number 31112-A70A0 is verified as the correct genuine in-tank fuel filter for the Hyundai Elantra MD, Kia K3, and Hyundai Veloster gasoline engine models.
