This is a Genuine OEM Fuel Filter, identified by the Hyundai/Kia MOBIS part number 31911-02100. The search results confirm this is the correct factory-original fuel filter for the Hyundai Atos / Atoz series, which uses the smaller 1.0L and 1.1L gasoline engines manufactured in the late 1990s and early 2000s.
Unlike later models that use an in-tank filter, this part is an In-Line Filter, meaning it is installed externally, typically along the fuel line between the tank and the engine bay, making it relatively easier to access and replace.
MPI System Protection: Although these engines use an older Multi-Port Injection (MPI) system compared to modern GDI, clean fuel is still critical. This filter removes contaminants like dirt and rust particles that can damage the fuel pump and cause blockage in the fuel lines or injectors, leading to poor performance or hard starting.
Genuine Quality: Using the Genuine MOBIS Part ensures the filter housing is robust, the internal filtration medium has the correct micron rating, and the threaded fittings (M14x1.5) match the fuel lines perfectly, preventing leaks and maintaining proper fuel flow.
Fitment Assurance: The part number 31911-02100 is verified as the correct genuine in-line fuel filter for the Hyundai Atoz (1.0L/1.1L Gasoline models).
