I would be interested to know if the dealer can give you that info. A few people have asked, and the dealer can only provide a part #, clean, and check resistance across the terminals. They have no need to know that since on a stock motor there would be no need to change the size. After contacting Bosch, they would not even give out that info. The best thing to do is to take them to a shop that can bench test the injectors.
