Which modification to choose depends on individual needs, if you are more concerned about the appearance, you can choose the appearance kit; If you're looking for more performance, consider engine changes.

A: Engine modification procedures may affect fuel consumption. Some modifications may result in increased combustion efficiency and thus improved fuel consumption. However, if the modification results in improved engine performance, it may result in more fuel consumption. The ultimate fuel consumption impact depends on the specific modification and driving habits.

A: Modified cars can provide the following benefits:

• Improved performance: Modifications can increase horsepower, torque and acceleration, improving the overall performance of the vehicle.
• Improved handling: Installing performance suspension systems, braking systems, etc., can improve vehicle handling performance and enhance the driving experience.
• Personalized customization: Modification can make the vehicle more in line with personal tastes and needs, to achieve personalized customization.
• Improve curb appeal: Installing kits, modifying wheels, etc., can improve vehicle curb appeal.
