Replacing the weather seals around a Honda NSX can provide several benefits. First, weather seals help to keep water, dust, and other debris out of the car, which can help preserve the car’s interior and keep it looking new. Second, weather seals help to keep the air conditioning and heating inside the car, which can improve the car’s energy efficiency and help keep the passengers comfortable. Third, weather seals also help to reduce road noise and wind noise, which can make for a more pleasant and relaxing driving experience. Fourth, weather seals can also help to prevent rust and corrosion, which can extend the car’s lifespan. Finally, weather seals can help to improve the overall seal of the car, which can prevent the entry of fumes and other pollutants.
