Definetely go with an intake. You can get the pipe from a few places... Check out SPmotorsport.com. You'll need a maf adapter, from SP as well. ANd pick up a K&N RU3530. Very popular choice. Next i would say go with an svt exhaust... Or maybe some other type of cat back. There are many other things you can do, use the search and check the stickies.
