I got my z tube in today and just installed it. When I got through putting everything back together, I noticed there was an extra vacuum hose next to the throttle body. Does anybody know where this goes?

 

what size it?

 

thats a coolent line btw.

 

A coolant line that plugs into the stock intake tube?

 

You said it was next to the tb

 

Oh big is it?

 

It's close to the throttle body, to the right of the intake tube. It's about half an inch opening.

 

that plugs into the Z tube...

 

There's no where to plug it in to...

 

Nevermind, I found it. The stock one is on top and the z tube one is on bottom. I couldn't see it because I was working in the dark, so when you said it plugs into the z tube, I went and felt around for it, and voila. haha, sorry guys.

 

honest mistake i guess. i was thinking it was one of the smaller hoses connected to the tb that you might have knocked of on accedent.

 

Ahh, I know what you're talking about. Thanks for the help everyone, really appreciate it.
Next step: MREV2 and 5/16 ISO Thermal spacer.

 

Try and pick those up used if you can, you'll save a bunch of money. And from my experience a spacer is a spacer... as long as its not damaged.

 

You're saying I don't have to get the ISO Thermal Spacer? The regular spacer would be just fine and add about the same amount of hp?

 

The ISO thermal part prevents heat from the tb from entering the the plenum. I say its worthwhile, since the plenum stays noticably cooler.
