As many of you know I am building a motor for my S3. I ordered "Motronic" pistons from Vick Auto only to find out (thanks RJ) that they are not but older Borga style and they could not even tell me the manufacturer! I told them they advertised them as Motronic but they were full of nothing but double talk and started having a fit about me sending them back and would not supply me with a shipping label. I personally will NEVER do business with them again. I was warned that they sell inferior parts and this is a perfect example. Do buy from these losers.
