I have a 2001 Hyundai accent automatic 1.5l. I recently have gotten an interest in cars/car modding. This is my first car and I think it would be cool to mod it. I want to leave the exterior as stock as possible. I want to add inside components to increase horsepower and speed in general. Ive looked at cold air intakes and catalytic converters as well as exhaust systems. I really don't know where to find parts and the practicality of doing this. Should I just save and invest in a different/easier car to mod or keep this one and take it on as a project? Any help?
