Who makes the original Porsche water pumps?

I withdraw the question. I can't believe that no one else considers this a reasonable question, and that no one seems to know the answer or even care. The thought seems to be that as long as a dealer sells it for $300 to $400 it's the best there is regardless of the manufacturer, but beware of everyone else. Just like saying my doctor says I need brain surgery and that's all I need to know, don't ask any other questions. I have seen doctors, lawyers, car dealers and people in all other walks of life that are dumb as a box of rocks and I see no reason not to get all the information I can before I make decisions.
