What is bolt on car?

Bolt-on car modifications are upgrades or changes that can be installed onto a car without any major modifications or structural changes. These modifications often require simply removing a component or parts and bolting on a new one. Examples of bolt-on modifications include air intakes, exhaust systems, suspension components, engine tuning modules, and cosmetic upgrades like body kits and spoilers. Since bolt-on modifications don't require any major modification to the car's chassis or structure, they are generally less expensive and easier to install than more involved modifications like engine swaps or turbocharger installations. Bolt-on modifications can be a great way to improve a car's performance, handling, and appearance without breaking the bank or taking on major mechanical work.
