Will universal modification parts affect the performance of the car?

‌General modified parts have many effects on car performance, depending on the type and quality of the modified parts. ‌

Specific effects of different modified parts on car performance ‌Throttle controller‌: can adjust the throttle opening and reaction speed, improve the vehicle's sensitivity at low speed and power output at high speed, and help save fuel‌. ‌Soundproof cotton‌: absorbs and isolates sound waves, reduces noise, and improves driving comfort‌. ‌Air filter‌: filters impurities and dust. Choosing a suitable air filter can improve intake efficiency and thus power‌. ‌Spark plug‌: affects engine power and fuel consumption. Regularly replacing high-quality spark plugs can improve the ignition effect and save fuel‌. ‌Thermostat‌: controls coolant flow and temperature. Choosing a suitable thermostat can optimize engine performance and fuel consumption‌. ‌Battery‌: provides power reserve and starting current. Choosing a high-quality battery can ensure a stable power supply and a fast start‌. ‌Brake system‌: Modifying the brake system can improve the braking effect. Choosing reliable parts from big brands and having them operated by professional technicians can ensure safety and performance‌.
‌Wheels and tires‌: Replacing the appropriate wheels and tires can improve handling performance, braking effect, and driving stability, but improper replacement may increase fuel consumption and damage vehicle stability‌.
Positive and negative effects of modification on vehicle performance ‌Positive effects‌: Reasonable modification can significantly improve the power, handling, and fuel economy of the vehicle while improving the driving experience and comfort. For example, high-performance air filters and exhaust systems can increase engine power and torque, and upgrades to the suspension system can improve handling performance and stability‌.
‌Negative effects‌: Improper modification may lead to problems such as increased fuel consumption and decreased vehicle stability. For example, wheels that are too heavy or of inappropriate size will increase rolling resistance, leading to increased fuel consumption; inappropriate suspension settings may reduce comfort‌.
Modification suggestions and precautions ‌Choose high-quality modified parts‌: High-quality modified parts from regular manufacturers usually improve vehicle performance, while low-quality modified parts may hurt vehicle performance‌.
‌Professional installation‌: It is recommended to choose a professional technician to perform the modification to ensure the modification's effect and safety. Unprofessional installation may cause performance degradation or even safety hazards‌.
‌Legal and compliant‌: Car modification must be carried out under the premise of legality and compliance. Uncompliant modifications may affect the safety and reliability of the vehicle and even violate traffic regulations‌.
