I was snoopin around on the net and came across this, I don't know if anyone has seen these before but I thought they were pretty sick. They got a full aluminum intake manifold that bolts on like a 70mm throttle body and even without a tune the power increase is really noticeable from what I can tell in the video.

Well it has been dyno tested. And it hurts low end. Top end its a sick *** intake. So its more for guys going for F/I set ups. Now looks it is the sickest. And it makes it pretty easily possible to mount a Supercharger for the 4.6 stangs on there.
