How should the air go in?

I took the engine killer off the Shovel and put the super E on but I didn't have a small air cleaner ( I hate those teardrop S&S ones ). So I got this crazy idea to make one out of an amp gauge face plate off this three faze generator we are scraping. Here are some shots from the garage tonight, almost done.

I need to put a filter element in and rap the outer screen and on it goes.
It's going to look bad ass, I like the glass window on it.
