I picked up most of my stuff on the bay. If you take your time you can find some good deals and everything you need

Prices to look for:
< 80$ for the nose piece
< 80-100$ for the box (make sure to get the right part#) I took a chance on a box that had the v6 nose piece on it already and it was the wrong one so basically I over paid for the nose.
I paid 37 each for the tubes new at a MB dealer.
Throttle body is a separate mod.

Had mine apart last night for cleaning, K&N install and some mods. I did not remove the ribs like bjames, they extent into the middle of the box and kind of guide the air to the hole in the back. You can separate the entire thing and get rid of the ribs throughout though if you really wanted. Figured they are not going to make or break the mod so just left em.
