Wiper Blade Bosch Aerotwin Upgrade AR17U

The Bosch Aerotwin Upgrade AR17U boasts a frameless construction and measures 425 mm for reliable performance.

Frameless wiper blade offers a modern tensioned beam, calibrated for constant glass contact across complex windshield curves. A pre-curved spring-steel beam pairs with a advanced synthetic-rubber edge, ensuring a silent, streak-free sweep. Its low-drag aero spoiler cuts lift at highway speed, while smart-fit mounting heads suits 95% of vehicles for hassle-free fitting. The frameless build shrugs off snow and ice, eliminates corrosion points, and hugs modern glass shapes for superior visibility. Drawbacks: higher upfront cost, refill inserts are non-serviceable, plastic adapters may embrittle in severe cold, and clamping force declines slightly on very flat windshields. Rinse with pH-neutral soap every three months and replace every 12–24 months (6–12 months in extreme climates). Experience silent clarity – upgrade now.
