The Z tube is the intake tube from the 350Z, hence Z tube. The difference is, and you'll see this when you do the install, is that the G35's intake (G tube if you will) has a chamber to lessen the noise the intake makes; the Z tube doesn't. Its the same materials, same basic shape, the Z tube will increase noise at WOT. If that doesn't bother you, go ahead and get it. If it does, then its really not necessary, you won't get much power out of the Z tube compared to the G tube.
As for the tough rubber seals (probably the hardest part of the install), the side clamp that comes with doubles as a good tool to spread the rubber out a little to get them on, especially around the scoop on the car as it is quite a bit thicker than the heat shield. You'll see what I'm talking about when you get it.
