My car is stock. My budget is 1000 dollars, can anyone tell me some mods that l can install on this car to make it faster. thanks a bunch.

For a thousand dollars start asking around the DYNOMETER shops. They know which exhaust and air intakes make the biggest gains. Sometime just by reworking the fuel tables and spark advance curves there is power to be made. Cold air intake exhaust is just about your budget limit right now. Dyno time some times get is expensive but it is necessary to see just what it is making stock and with exhaust installed and air intake. .
