Turbo inlet differences

Someone on FBM has a Corksport TI for sale. Looking at the connections on it, it does not match the TI CS is currently selling. It does match the connections for CS Stage II Short ram inlet pipe.

I currently have a K&N cold air intake on my car with the stock turbo inlet pipe. Will the Stage II inlet work with my K&N and is there are benefits of using the stage II inlet pipe vs getting the other inlet pipe CS offers?

The stage II that matches the one on FBM:

The other TIP CS sells:

From FBM:

 

The stage two moved some shit and needs an aftermarket sri the regular tip works with the stock airbox.

For your setup maybe you need to look at which connections are on a which piece and you might need to macgyver some shit
