Wiper Blade Set Bosch Aerotwin A821S

Description

Set of wipers Bosch Aerotwin A821S includes blades of 600 mm / 600 mm and offers a frameless construction.
Enjoy crystal-clear clarity year-round with the A821S set of two all-weather wipers — crafted to stand up to rainstorms, freezing rain, snow, and blazing sun without missing a beat.

The Bosch A821S wiper blade set offers an advanced asymmetric deflector, designed to deliver exceptional wipe quality in challenging environments.
An asymmetric spoiler is strategically positioned to channel airflow into optimal contact force while minimizing drag, applying extra pressure to the wind-facing edge so the blade hugs the glass during gusty conditions. The result is minimal noise and vibration even in turbulent weather.
Ideal for highway commuters, it enhances stability for a smoother drive.

Frameless wiper blade unleashes a streamlined flat spine, precision-engineered to maintain even line pressure across multi-radius glass. A resilient metal spine pairs with a advanced synthetic-rubber edge, ensuring a crystal-clear pass. Its wind-cheating contour reduces drag, 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 – elevate now.

Series Aerotwin – the top series from the renowned global automotive supplier Bosch. Wipers in the Aerotwin family offer an modern frameless construction and are supplied to the plants of many European vehicle makers. The wiping element is made from a high-tech composite rubber, outperforming natural rubber in key properties. Spring rails are produced from a special “Evodium” alloy and maintain their original tension throughout the blade’s service life.
