Description
This 500 + 475 mm Wiper Blade Set Bosch Aerotwin AR503S features a frameless assembly.
Engineered for all-season use, the set of wipers Bosch Aerotwin AR503S maintains perfect contact and crystal-clear cleaning across both blades in any weather.
The Bosch Aerotwin AR503S wiper blade set integrates an advanced asymmetric deflector, designed to deliver exceptional wipe quality in diverse weather.
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 minimal noise and vibration even in demanding high-speed scenarios.
Ideal for highway commuters, this spoiler boosts wipe efficiency for a smoother drive.
Frameless replacement blade offers a modern tensioned beam, purpose-built to hold constant glass contact across today’s sculpted windshields. A resilient metal spine pairs with a premium silicone edge, producing a silent, streak-free sweep. Its low-drag aero spoiler boosts high-speed stability, 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.
