I love how all the noobs are preeching about how "headers" and "Cold air intakes" are mods that add any kind of power lol. The fact of the matter is, like fathergoat says your gonna get MAYBE 15hp max. As far as teh differene between CAI and short ram, its negliable, that is untill your CAI, making 1 extra hp, decides to make a new life for its self as a straw, and you get a paper weight for a motor. Now the other guy, who claims to know how much he made to the flywheel before and after his coldairintake, im EXTREMLY curius how you figured those numbers, as engine dynos are not all together common and definenently not cheap enough to justify finding the power of CAI.
At 16, with all seriusness, make the car FUN to drive, because if you have a fast car your gonna do one or both of 2 things. Wreck the car and kill someone else, or your self, OR Drive like an absolute douch and rack up so many tickets your insurance will be bending you over even your driving a Geo Metro. So get a nice stereo, keep the car clean, and enjoy the car for what it is, slow commuter
