The cobra kit includes all of the following, clutch kit Phase 2, exhaust mod, head work, jets, and cold air kit. As for the cold air kit I can tell you that it does work on my machine and when Dynoed showed HP increase from 2-4 HP and the instructions you get with it to install my grandmother could follow. For the cost it is probally the cheapest mod for the gain result.
