Description
The Bosch Aerotwin A963S comes as a frameless assembly set of wipers with 746 + 646 mm blades.
A963S – an year-round wiper blade set delivering crystal-clear vision in rain, snow, and heat for year-round reliability.
This Bosch A963S set of wiper blades showcases an asymmetric spoiler, designed to deliver reliable performance in all conditions.
An asymmetric spoiler is strategically positioned to channel airflow into focused windshield grip while reducing aerodynamic resistance, applying extra pressure to the wind-facing edge so the blade hugs the glass during gusty conditions. The result is reduced lift and chatter even in turbulent weather.
Ideal for highway commuters, this spoiler boosts wipe efficiency for a smoother drive.
Frameless replacement blade delivers a modern tensioned beam, purpose-built to hold even line pressure across complex windshield curves. A pre-curved spring-steel beam pairs with a advanced synthetic-rubber edge, ensuring a whisper-quiet glide. Its wind-cheating contour boosts high-speed stability, while smart-fit mounting heads suits 95% of vehicles 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 – elevate now.
Series Aerotwin – the premium line from the respected European automotive supplier Bosch. Wipers in the Aerotwin family offer an modern frameless construction and are supplied to the production lines of numerous leading vehicle makers. The wiping element is made from a high-tech composite rubber, offering better performance than natural rubber. Spring strips are produced from a special “Evodium” alloy and maintain their original tension throughout the blade’s service life.
