Is it illegal to stick diamonds on the original car emblem?

[Jesse]

Sticking diamonds on the original car emblem is not illegal: The following is an introduction to the hazards of car modifications: 1. Carbon fiber engine hood modification: This is the most dangerous modification. The original hood can deform and bend in stages during a collision, while modified parts may directly pierce the windshield, causing accidents. 2. Installing a mushroom head exhaust pipe: A mushroom head exhaust pipe can reduce intake inertia, leading to decreased low-speed torque, increased fuel consumption, and reduced low-speed power. 3. Upgrading to a large exhaust system: This reduces exhaust backpressure, resulting in decreased low-speed torque, and the engine exhaust valves may burn out easily due to extremely high temperatures. 4. Replacing with platinum spark plugs: Any new spark plug, whether it's an expensive platinum one or a cheap one costing a few dollars, will initially improve engine performance because the insulation of a new, uncontaminated spark plug is good. However, after a few days of use, it will return to its original state.
