That (22680AD200) is the correct part number for the Mass air flow meter assembly for 2000-2001. From the end of 2001 to August 2004 they used 22680AD201. Either of those part numbers are suitable. Those part numbers are for a complete assembly. You can also purchase just the sensor itself which is usually the problem. Part number is 22680AD21A or 22680AD210.
Note this information I have is for Australian spec vehicles and may differ in Europe as I do not have access to Euro information.
