Most of that crap is for emissions. You can chunk 80% of it. The big ones you need are...
-The brake booster is the one you really have to worry about.
make sure ALL the lines are hooked up to your vacume tree (on the firewall next to the master cylender).
-Fuel regulator vacume line. This one is a small one.
Those are the one two I hooked up on my new intake. I don't have a Cobra intake, but as far as vacume, we should have the same. Hope this helps you out.
