Air Intake Hose Routing

[PINOYROADIE]

Does anyone know where I route the hose for the small nipple on the air intake tube?

I no longer have my S13 and now i'm helping my brother with his. He bought his car without a motor in it. Basically bare engine bay. I see alot of threads with vaccum line routing but I cant find anything about the routing of the lines that go to the air intake tube. I'm guessing because it's so simple to change out your stock for a cold air intake.... Unless there was never anything there to reference from.. I know one goes to the Valve cover. The other to the metal pipe that goes to the AIT.. I just don't know where the little nipple gets routed to.. Thanks in advance!

But on the stock intake there are three nipples as well.

1 on the Boot that goes to the Throttle Body and 2 on the hard plastic intake tube that crosses above the fan shroud.

This might help, apparently it goes to the PAIR valve (AIV) and t'd to a hard line under the intake mani. When I had my old ka setup the previous owner removed the PAIR valve, which I think most people do. There's other threads about it's purpose and removal incase you were wondering.

It should go to your egr valve
