Filters and drain plugs for motor oil of scooters. Are you going to change the motor oil of your scooter? Then you should always install a new oil filter. These are full of waste from the motor oil. You do not want this waste in your block and that is why you have to install a new and clean filter. All Vespa/Piaggio models have the same oil filter. All China/GY6 scooters also have the same filter. So that is nice and easy! So you do not have to search for which filter you need.
