Nitrous kit.
Pod filter!!!!!! And some fully sick chromies
buy a new car. If you want fast....that's the only way. Everything else (cold air intake, fart pipe, etc) will NOT make the car any faster.....except for the fact your wallet is lighter. The only REAL way to make that car fast is to spend big $ and have a blower installed, plus new timing and fuel maps. But then, you've got a faster slow car. Basically, you just made a joke of yourself. If you want fast, simply buy fast.
edit- yes, you could also install a nitrous kit....which would add (safely) 75 hp. But, why? You'll still have a fairly slow car, but you'll be doing damage to the engine.

I have a 2005 mazda 3s sedan. I want to start modding it and turn it into a cool little tuner car I guess you could say. Speed and looks. What do I need to do and are there any websites where I could find parts. Like americanmuscle.com but for cars like that. I'm born into an american muscle family so I'm not sure about anything when it comes to foreign cars but I feel like trying something new.
