To the people using the 5th gen TB and 4th gen IACV, i know you can take the air from the mid-pipe to the IACV, but where on the 00VI upper intake manifold does the air go back in, i have seen that maxS has made a custom hole right next to the TB by using a 90 degree elbow and some have done something else. Anybody have any suggestions on what the easiest route might be. i looked through all the threads and people talk about the 4th gen IACV gets the air from the mid-pipe goes through the IACV and then to the upper manifold, yet no detailed pics or explanations. any help would be great. thanks

 

I would do the 90* elbow like MaxS if you really wanna keep the IACV (when we did s0ber's we didn't use an IACV, we just rised the idle speed and it runs with no starting/idling problems at all).

 

when running the 90 degree elbow, it replaced an already existing elbow, what is that existing elbows function? because i dont wanna remove it and realize later on that i'll need it

 

Its just another vacuum sticking out... Which you can replace, im using it for my EGR/EVAP vacuum source
