Tuning cars involves modifying their performance and design characteristics beyond what is offered from the manufacturer. Common modifications include changing engine components like air filters or exhaust systems to increase power, upgrading brakes and suspensions for improved handling, and adding exterior modifications like spoilers, body kits, or new wheels and tires for aesthetic changes. The goal of tuning is to create a vehicle that performs better on the road or track while expressing an owner's unique style and preferences.
