I sold a stock upper and lower intake on ebay about a week ago. I have had the intakes for a couple years and to my knowledge they we unmodified. The buyer sent me a message that the upper intake had been polished.
Here is what the buyer said. " I bought this manifold because it was listed as origenal, and not port polished. And its polished, on top of that its over polished. for proper fuel atamizattion ports should never be sanded past 80 grit . this looks like 120. its not worth what I paid. max Ill pay is 200.00.
I just want to know if the part about fuel atomization is true?
