Bosch AeroTwin with patented Power Protection Plus technology, Bosch Aerotwin wiper blades provide excellent wiper performance under any weather condition, quiet wiping, and an increase in service life. Bosch Aerotwin wiper blades feature customised spring strips made of high-tech, Evodium steel. These spring strips ensure consistent high pressure across the entire length of the blades, pushing the blades on to the windscreen to avoid any wet patches during operation that could inhibit your vision — and it does it all without juddering or squeaking. Combined with an aerodynamic design that reduces windage, the Aerotwin wiper blades provide the most silent operation possible.
