Wiper Blade Set Bosch Aerotwin A422S

Description

The Bosch Aerotwin A422S wiper blade set includes blades of 650 and 400 mm and boasts a frameless design.
Built for every season, the set of wipers A422S stands up to harsh weather and road salt to keep your view perfectly clear.

This Bosch A422S set of wiper blades incorporates an asymmetric spoiler, built to provide exceptional wipe quality in challenging environments.
An asymmetric spoiler is strategically positioned to channel airflow into enhanced blade pressure while minimizing drag, applying extra pressure to the wind-facing edge so the blade hugs the glass during fast-paced drives. The result is reduced lift and chatter even in demanding high-speed scenarios.
Perfect for performance-driven drivers, it boosts wipe efficiency for a smoother drive.

Frameless replacement blade delivers a sleek beam profile, precision-engineered to maintain even line pressure across multi-radius glass. A resilient metal spine pairs with a premium silicone edge, producing a whisper-quiet glide. 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). Go beam, drive clear – purchase today.
