This is a Genuine OEM Fuel Filter, identified by the Hyundai/Kia MOBIS part number 31112-J3001. This filter is a factory-original component designed for the fuel pump assemblies of the later generation Hyundai Elantra (AD chassis) and related compact models, specifically those equipped with the reliable 1.6L and 2.0L Gasoline engines from approximately 2017 onwards.
The function of this in-tank filter is essential for the advanced fuel injection systems:
GDI System Protection: Modern GDI engines have extremely fine injector nozzles and require high, stable fuel pressure. The filter's primary job is to remove the smallest particulate contaminants, preventing catastrophic damage to the fuel pump motor and injector fouling.
Pressure Integrity: Located inside the fuel tank and integrated into the fuel pump module, the Genuine MOBIS Part guarantees the exact fitment, sealing, and filtration capacity needed to maintain the precise fuel pressure dictated by the engine's ECU, which is crucial for optimal performance and fuel efficiency.
Correct Revision: This part number represents a specific revision for the fuel pump assembly used in these models, differentiating it from earlier generations of the Elantra/Cerato.
Fitment Assurance: The part number 31112-J3001 is verified as the correct genuine in-tank fuel filter for the Hyundai Elantra AD 1.6cc (primarily 2017+ models) and the newer Kia Cerato K3 1.6cc.
