Can the car engine be modified?

[DiCharlotte]

Engine modifications are possible. Modification principles: Relevant officials from the vehicle management office have made it clear that as long as the modifications do not affect driving safety, they are not prohibited and can pass the annual inspection. Market response: The two important principles of modification are safety and practicality. 'Modifications' are usually basic, such as adding a bumper, spoiler, car stickers, or replacing the audio system, high-voltage wires, spark plugs, etc. Precautions: According to modification experts from car manufacturers, replacing the headlights with xenon lights is safe for driving itself, but drivers must adhere to the regulation of switching from high beam to low beam when approaching oncoming vehicles within about 100 meters at night, so as not to affect the visibility of other vehicles. As for installing a sunroof, since it alters the structure and load-bearing capacity of the car's roof, reducing safety performance, it is best not to modify it.
