Description
Bosch Aerotwin AR644S – wiper blade, 700 mm long, developed using a frameless design.
Built for every season, the Bosch Aerotwin AR644S windshield wiper resists extreme weather and road salt to keep your view perfectly clear.
The Bosch Aerotwin AR644S wiper blade boasts an asymmetric spoiler, crafted to ensure resilient performance in high-speed scenarios.
An asymmetric spoiler is strategically positioned to channel airflow into optimal contact force while reducing aerodynamic resistance, applying extra pressure to the wind-facing edge so the blade hugs the glass during rapid commutes. The result is reduced lift and chatter even in strong crosswinds.
Perfect for performance-driven drivers, this spoiler enhances stability for a smoother drive.
Frameless replacement blade unleashes a sleek beam profile, calibrated for pinpoint wiping accuracy across multi-radius glass. A pre-curved spring-steel beam pairs with a advanced synthetic-rubber edge, producing a silent, streak-free sweep. Its low-drag aero spoiler cuts lift at highway speed, while smart-fit mounting heads suits most makes and models for rapid installation. 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.
Series Aerotwin – the premium line from the respected global manufacturer Bosch. Wiper blades in this line offer an modern frameless construction and are supplied to the assembly lines of numerous leading vehicle makers.
