RSG said:and...ok, I'm an idiot but what is the 4" metal tube supposed to hook into? I suppose it is inline with the turbo intake, but why? Is that the section that the stock system sucks the vapors into the turbo? If so, what happens to the turbo when it loses all that lubricant, is that a problem?
Anybody done this with the aFE intake tube to the turbo?
Its inline between the two factory rubber hoses.
Since you are rerouting the ccv tube out of the factory plastic connecting tube you are going to leave a large hole that must be plugged. You also will continue to have the air flow obstruction with the old tube. The 4" metal tube omits both these problems.
