I did some investigation into intake runners this morning,for my TDI they would need to be 3 feet long to have effect at the lowest rpm possible, around 4100 rpm.
The max rpm i drive is 2150, at my hwy speed & shift at 1500 to 1700 rpm.
Now i know why some hot rods have huge piped intake runners, I assume the headers/ exhausts work in conjunction.
