The easiest modification is to get a cold or warm air intake system. If you go to you will find some help on choosing places to find this performance item. You will also get a discount when you order through the site by clicking on the ad banners or text links and purchasing it that way. But, you can still call first and get tech help on what would be the best system for your car. I would reccomend using the retailer called HorsePower Freaks. You will find them under retailers in the main drop down menu or just click the link on the home page.
