Wiper Blade Set Bosch Aerotwin RLE A423S

Description

Set of wipers Bosch Aerotwin RLE A423S comes with frameless assembly and includes 650 + 400 mm blades.
Built for every season, the wiper blade set A423S resists extreme weather and road salt to keep your view perfectly clear.

The Bosch A423S set of wiper blades features an advanced asymmetric deflector, built to provide superior visibility in high-speed scenarios.
An asymmetric spoiler is strategically positioned to channel airflow into enhanced blade pressure while reducing aerodynamic resistance, 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.
Ideal for highway commuters, this spoiler boosts wipe efficiency for lasting clarity.

Frameless replacement blade offers a modern tensioned beam, calibrated for even line pressure across multi-radius glass. A pre-curved spring-steel beam pairs with a premium silicone edge, ensuring a silent, streak-free sweep. Its low-drag aero spoiler 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.
