Car tuning refers to the process of modifying a vehicle's performance and appearance to enhance its capabilities or aesthetics. This can involve adjustments to the engine, suspension, exhaust system, and other components to improve speed, handling, and fuel efficiency. Tuning can also include cosmetic changes, such as custom paint jobs, upgraded wheels, and interior modifications. Enthusiasts often use aftermarket parts to achieve their desired results, and tuning can be tailored to specific driving styles, whether for racing, off-roading, or daily commuting.
