Wiper Blade Set Bosch Aerotwin AR503S

Description

Bosch Aerotwin AR503S – set of wipers, 500 mm + 475 mm, available in a frameless version.
Built for every season, the set of wipers AR503S stands up to extreme weather and deicing chemicals to keep your view perfectly clear.

This Bosch AR503S set of wipers boasts an asymmetric-style spoiler, optimized for exceptional wipe quality in all conditions.
An asymmetric spoiler is strategically positioned to channel airflow into targeted downforce while minimizing drag, applying extra pressure to the wind-facing edge so the blade hugs the glass during highway speeds. The result is a smudge-free wipe even in strong crosswinds.
Tailored for windy climates, this spoiler enhances stability for a smoother drive.

Frameless replacement blade unleashes a modern tensioned beam, precision-engineered to maintain constant glass contact across multi-radius glass. A resilient metal spine pairs with a advanced synthetic-rubber edge, producing a whisper-quiet glide. Its low-drag aero spoiler boosts high-speed stability, while tool-free quick-click mount 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 – take your drive to the next level now.
