I would say disregard below. I was worried after reading this but checked the part number on the werks racing website and it is the correct part, same as if you ordered replacement through them, so I purchased this one as cheaper through A-main. Mine arrived and it is a thing of beauty indeed, and the piston is domed just like the original one, it is most definitely the factory replacement part.

Werks 5-Port B5 Piston/Sleeve Set
this is not the same part that comes in the new b7 , the piston sleeve should have more machining around the the bottom edge of the sleeve and the piston itself should be domed , these are not !!!!
