See my thread to check out how i've set up my ze.....
Sprintah - Given where the ZE thottle body sits (start of the intake) the whole inlet tract sees full vacuum. So anything flexible will be sucked in. Use metal bends and SHORT silicone or rubber joiners where needed.
Frontmount ICs are good. Throttle response and idle are affected but you can easily live with it. Just don't go silly with size.
