s5 intake with s4 engine vac problem?
 

I am trying to run a s5 na intake on my s4 na. I have been trying to use the vac diagrams but there are some things that I can't figure out. Like how to re route the bac and where I connect the vac spider. I will post pics tomorrow. Can anyone shed some light?

I think I have a link saved on my other computer. I`ll find and post it later today.

Im doing the same thing right now. I just used the small hose from the old hard line that went to the bac, and hooking it up straight to the air intake pipe. i hav eno clue what im gonna do fo rht erest of the stuff, but as of right now, i have a minor vacuum leak, so i am trying to trace that down first, before i worry about the other stuff.

Both the spider and input for the BAC attach to the small intake tube sticking out the bottom of the intake tube between the AFM and the throttle body.

thx icemark but I was also wondering how other people reran the hose that goes to thermowax?
anyone have pictures?

What I did was use the hose that comes from the front of the motor to the bac, and reversed it onto the thermowax.

Then just ran a new hose from the front of the motor to the bac.

I should have been more clear, I am looking for a picture of the upper and lower intake mani because I still can't figure some of the vac hoses out like the fuel injector air bleeds and some small others. Icermark you have answered my original question and made it even more simple for me thx man.

all the air bleeds (Fuel injectors and oil injectors) all feed to that line on the intake tube.

two more questions

what do I do with the large vac tube coming out the back of the upper intake(next to vdi)

and what do I do with the tube coming off the left side of the lower intake mani(while lookin at it on the engine)

thx icemark for the otherquestions the answers were right in front of me.

, cap it off.

Hmm I think you mean the other small line, next to the big one??? That I used for the cruise control.

the one that kind of goes up in the air, I will go take pics
