Kram; First I am a Newby to water cooled Porsches. I can see that you spend a lot of time updating/improving your car so I am sure you have done a lot of research. The point I was attempting to make (excuse my brevity in previous posts) was that this is not a part to gamble with, since severe damage can result from cheap/inferior parts. The OP was looking on Ebay! Caveat Emptor is not worth saving a few bucks. While the Genuine part I was shipped is indeed made by Pierburg, I can rest assured it is Genuine and a quality part. Remember there are a lot of newby like me that look to this forum for guidance. "Porsche, accept no substitute!" Edit; Unless it is made better! Thanks to LN engineering and Jake .
