Does replacing a car door have any impact?

[SanAthena]

Replacing a car door mainly has two impacts: color difference in the paint and reduced sound insulation. The details are as follows: 1. Color difference in the paint If the door is replaced at an external repair shop, the repainted door may show a color difference compared to the original factory door. If a door replacement is necessary, it is best to have it done at a 4S shop. 2. Reduced sound insulation Similarly, if the door is not replaced through official channels, issues may arise in the assembly process or details, leading to air leakage or increased noise during high-speed driving, which reduces the car's sound insulation and affects the comfort inside the car.
