Auto tuning is a hobby or pastime that involves modifying and customizing vehicles to improve their appearance, performance, and sound. It involves applying different aesthetic and technical enhancements to the car with the aim of making it a unique and eye-catching piece.
In terms of aesthetics, auto tuning seeks to enhance the vehicle's appearance by installing body kits, spoilers, side skirts, rear diffusers, and other elements that provide a more aggressive and sporty look.
Regarding technical improvements, auto tuning aims to increase the car's performance through modifications to the engine, suspension, exhaust system, brakes, and other components. This can include changes to the air intake, engine power, electronic management, and modifying the exhaust systems to achieve a more aggressive sound, among others.
