Car Accessories That Reduce Noise
Some exterior accessories cut noise: U-shaped door-edge seals close gaps that whistle at speed, and well-fitted trim reduces flutter. They will not silence a worn cabin, but they help.
Seal the gaps
U-channel rubber seals around door edges reduce wind whistle on the highway.
Manage expectations
These trim wind noise, not engine or tire roar; pair with good tires for best effect.
