I suggest you do a lot of reading up here (advanced search is your friend; learn to use it and you will be giving yourself the best help available) before you go spending any money on "easy bolt on mods that will increase HP/TQ ", especially since you have minimal experience. Bottom line is that there is a fairly limited amount available without forced induction, and what little there is of it comes at a relatively poor HP per $$ ratio.

Thanks for all the suggestions. I think ill just drop some better air filters in and leave the engine alone.
I did upgrade the speakers with Alpine 6.5 component set in the front and Alpine 6.5 in the rear, it sounds much better!

You must not have the Bose system? I thought from past cars with the Bose they make it difficult to swap speakers since they all back then had an amp to drive each speaker.

I did not have the Bose system. There are threads available on here that explain how to upgrade the Bose system though.
