Wiper Blade Set Bosch Aerotwin A621S

Description

Bosch Aerotwin A621S – frameless wiper blade set, 650 and 500 mm for optimal coverage.
Engineered for all-season use, the wiper blade set A621S maintains optimal contact and smudge-free cleaning across both blades in any climate.

The Bosch A621S set of wipers incorporates an high-performance asymmetric fin, built to provide enduring performance in diverse weather.
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 fast-paced drives. The result is a crystal-clear visibility even in demanding high-speed scenarios.
Perfect for performance-driven drivers, it boosts wipe efficiency for dependable performance.

Frameless windshield wiper blade offers a sleek beam profile, purpose-built to hold even line pressure across multi-radius glass. A pre-curved spring-steel beam pairs with a premium silicone edge, ensuring a whisper-quiet glide. Its low-drag aero spoiler reduces drag, while smart-fit mounting heads suits most makes and models 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.

Bosch Aerotwin – the top line from the renowned global manufacturer Bosch. Wipers of this range feature an advanced frameless construction and are supplied to the plants of numerous European vehicle makers. The wiping element is made from a high-tech composite rubber, outperforming natural rubber in key properties. Spring elements are produced from a special “Evodium” alloy and maintain their original tension throughout the blade’s service life.
