Intelligent Tension Strip Curved Strips Fit Perfectly on Windshield Allows even pressure to be applied to the windshield and greatly reduces wiping unevenly. By reducing the ground pressure of about 25% (compared to our company) compared to previous products, it has improved abrasion resistance and a longer life. The aerodynamic form spoiler reduces the appearance of air resistance and provides negative lift. Improved windshield adhesion to ensure a reliable wipe off even at high speeds and greatly reduces wind noise. Easy to install using a dedicated installation adapter for easy installation. *NOTE* When the wiper arm is elevated, the wiper blade is easier to fall off than the arm. Please be careful of dropping. Aero Twin wiper blades do not have replacement rubber settings. Compatible models: Volkswagen Touran (2006-later vehicles) Lancia Delta R
