You will have to modify the plastic intake ducts that the factory airboxes hook up to, this is so the intake pipe can pass through. You will need a dremel or something similar to grind out the material you don't need.

There should be a procedure in the DIY section of this forum (also there is more than likely videos on youtube)

If you don't like the idea of cutting into your car then the Z1 system is the next best, they use silicon hoses that pass through that section and are flexible enough so that you don't have to modify anything. The afe takeda also have flexible piping.

Hope this helps!
