As everyone else has been saying it obviously points toward the firewall. What I did was cut the runners and added about 30 degrees downward so the plenum fits under the hood. Otherwise it's way to high.
Here's before cut
Here's after 30 degree
After you get all the moch up shit done, you'll need to change your tps wires because it'll read backwards, make your own throttle cable and bracket, rewire the gtir IF you want iacv, and you'll obviously have to go topfeed. If you don't know how or don't want to sync itb's don't bother with the setup. You're going for performance and it comes at a cost of maintenance.

Great post - that sums it up. Note: cheapest way to do it (if you can fab stuff for free) is to use GSXR1000 throttle bodies on a stock (cut) plenum. The GTI-R setup is much cleaner though, and the plenum is the right shape for the ITBs/etc.
Sync'ing throttle bodies is not a huge deal, and makes an enormous difference in performance/smooth idle - just a vacuum gauge and a screwdriver
