Cold air intake or Supercharger for '06 Chevy Cobalt?

[Jessica]

I'm working on my '06 Cobalt, I would like to get a performance chip, cold air intake, supercharger one of these or all. I'm not sure how much hp, power or torque I would gain from installing any of these. Any ideas of which of these or which company to buy from?

It is a choice of buying something that will work and make ponies, compared to
something that will set you back a couple of hundred dollars and do nothing
except look cool when you raise the hood...
