If I may make a suggestion.
Before modifying to any extent, I suggest learning about what you have before wanting to change what you have. In due time you'll learn more then you ever expected. But instead of looking for a quick performance fix, take 5, learn about your vehicle.
I also second/third the need for FULL TUNE UP. Nothing will yield more results then a proper tune up. This alone will help you discover things about your car. If you have to take the tune up slowly, so be it. If you wish to upgrade plugs, wires, filters etc while doing your tune up, so be it.
If I were you, upgrading your intake before taking care of the basics, is just foolish.
