Who makes the original Porsche water pumps?

[mountainman]

It has been my experience that anyone who makes a quality product that they can be proud of and stand behind are not ashamed to put their name on it. Would you buy a tire with no name, or a car or anything else. Why a waterpump? I have owned several businesses and have never sold anything with no name on it. I like to know what I am buying and that was the whole point of this post, not to find a cheaper product or another vendor who wants to sell his product. I want to know who made the water pump that Porsche used when they assembled the engine in their factory. Why is that so difficult to understand?
