Adjusts air flow
By attaching it to the rear of the hood, you can achieve various benefits by adjusting the airflow around the vehicle.
Insect Repellent: In summer insects stick on the windshield and are difficult to remove dirt in order to improve the situation.
Reduces Glass Stains: Reduces dust, light rain and snow buildup to protect your windshield and hood from scratches and dirt.
Improved wind noise/squeak: The wiper will crush the air and produce a flattening sound while riding, allowing air to pass through and reduce wind noise and squeaks around the wiper.
Especially during high speed driving
