Description
Bosch Aerotwin A843S – set of wipers featuring frameless design, lengths 550 mm & 550 mm.
From sleet-covered streets to sun-baked highways, the A843S set of two all-weather wipers keeps your windshield spotless — and your drive safe.
The Bosch A843S wiper blade set features an asymmetric-style spoiler, engineered for superior visibility in diverse weather.
An asymmetric spoiler is strategically positioned to channel airflow into focused windshield grip while minimizing drag, applying extra pressure to the wind-facing edge so the blade hugs the glass during rapid commutes. The result is a streak-free visibility even in demanding high-speed scenarios.
Tailored for windy climates, this spoiler boosts wipe efficiency for lasting clarity.
Frameless windshield wiper blade delivers a sleek beam profile, precision-engineered to maintain constant glass contact across multi-radius glass. A pre-curved spring-steel beam pairs with a premium silicone edge, producing a silent, streak-free sweep. Its low-drag aero spoiler cuts lift at highway speed, 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). Go beam, drive clear – get today.
Series Bosch Aerotwin – the premium line from the renowned German manufacturer Bosch. Windshield wipers in the Aerotwin family feature an advanced frameless construction and are supplied to the plants of many leading 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” spring steel and maintain their original tension throughout the blade’s service life.
