How do I remove the lower intake manifold?

[Dadspathfinder]

Hello, I'm currently removing my lower intake manifold in order to get to my knock sensor. I've had already removed my fuel rails, and screws/allenwrenches that bolts the lower manifold down. However, I am running into a tiny problem. There happens to be a little piping that the lower intake have that somewhat attached or plugs into a metal wall facing the direction of the radiator fan.

How do I get this off? I've been trying to rock this manifold loose by shaking it back and forth. But, it's not coming off because there isn't enough room.... and the screws that holds it in place requires you to lift directly straight up and I cant do that with the piping attached to the wall. See pictures.
