Wiper Blade Set Bosch Aerotwin A821S

Description

Bosch Aerotwin A821S – wiper blade set made with frameless assembly, lengths 600 mm / 600 mm.
A821S provides resilient, year-round windshield cleaning, thanks to dual blades that effortlessly combat ice, snow, and heavy downpours.

The Bosch A821S set of wiper blades features an advanced asymmetric deflector, designed to deliver enduring performance in challenging environments.
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 turbulent weather.
Perfect for performance-driven drivers, it boosts wipe efficiency for a smoother drive.

Frameless windshield wiper blade offers a modern tensioned beam, calibrated for pinpoint wiping accuracy across today’s sculpted windshields. 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 tool-free quick-click mount 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.
