The shell is mostly aluminum or plastic, with a pleated paper core or nylon mesh inside.Every drop of oil sucked by the engine is sieved by it first to prevent the injector, oil pump and precision carburetor from being scratched or clogged by particles.Regular replacement can make the throttle smoother, cold start faster, and extend the life of the oil pump.After off-road or long-distance riding, the filter element is prone to dust accumulation. It is recommended to check every 2000-3000 kilometers and change it when you see the color darken.Choose the filter element and make sure that the shape of the interface matches the flow rate. When installing, pay attention to the arrow pointing to the engine, so that the car can drink “clean oil” all the way.
