Oil filter tool with 12 Points fits early B063428 and early 2A000668 series filters with the 12 point housing design.
Note: In typical Guzzi fashion, these oil filters do not always have the same housing. Early filters were 12 point housings requiring 12 point filter tools. Later, they switched to 14 flat housings requiring an oil filter tool with 14 flats. We cannot know version will be inside the next case of filters. For that reason, to cover your bases, you might want to have both filter tools on hand. Sometimes you'll need one type to get the old filter off, and another type to put the new filter on.
