Wiper Blade Set Bosch Aerotwin A621S

Description

Bosch Aerotwin A621S – frameless wiper blade set, 650 / 500 mm for optimal coverage.
Engineered for year-round use, the wiper blade set Bosch Aerotwin A621S maintains optimal contact and smudge-free wiping across both blades in any weather.

The Bosch Aerotwin A621S wiper blade set showcases an high-performance asymmetric fin, built to provide unmatched clarity in challenging environments.
An asymmetric spoiler is strategically positioned to channel airflow into focused windshield grip while minimizing drag, applying extra pressure to the wind-facing edge so the blade hugs the glass during highway speeds. The result is reduced lift and chatter even in turbulent weather.
Tailored for windy climates, it boosts wipe efficiency for lasting clarity.

Frameless replacement blade delivers a sleek beam profile, purpose-built to hold pinpoint wiping accuracy across complex windshield curves. A pre-curved spring-steel beam pairs with a premium silicone edge, ensuring a silent, streak-free sweep. Its wind-cheating contour cuts lift at highway speed, while tool-free quick-click mount 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). Go beam, drive clear – order today.

Wipers in the Aerotwin family boast an advanced frameless construction and are supplied to the assembly lines of numerous leading vehicle makers.

Spring elements are produced from a special “Evodium” spring steel and maintain their original tension throughout the blade’s service life.
