Now ive come to a hitch.... here goes:
the original piping between the intake plenuim and AFM there are 2 pipes going into it, 1 from the rocker cover, and the other from somewhere. Check picture.
Now i want to know do i need to still use these with the turbo engine, by plumbing them into the new pipe work? or can i bypass them??
What do they do anyway?
