The item "Oil filter screen Active" is an oil filter screen for Active mopeds. The screen filter traps large particles in the oil and keeps them from reaching the components that are lubricated under pressure.
The screen should be washed and inspected at every oil change. Replace it if the mesh is clogged with carbon or metal shavings, or if the screen is torn or deformed. When replacing it, inspect the neighboring parts of the assembly: they often wear out together.
