Ok, a quick questions.

On the center iron, right near the oil fill tube and dipstick, there is another nipple that points straight back towards the firewall over housing #2. What does this connect to stock?

Thanks!

N/a turbo ? S4 or S5? Might not be universal so that info might help a little too.

 

If i remember correctly....i think it circulates back into the intake.

 

That's the nipple to intake fresh air from the TID for the PCV system.
