Description
Bosch Aerotwin A991S – set of wipers, 600 mm + 400 mm, built with frameless technology.
From sleet-covered streets to blistering summer afternoons, the A991S twin-blade wiper set keeps your windshield perfectly clean — and your drive safe.
This Bosch A991S set of wiper blades boasts an asymmetric-style spoiler, optimized for unmatched clarity in diverse weather.
An asymmetric spoiler is strategically positioned to channel airflow into optimal contact force while minimizing drag, applying extra pressure to the wind-facing edge so the blade hugs the glass during rapid commutes. The result is minimal noise and vibration even in strong crosswinds.
Tailored for windy climates, it boosts wipe efficiency for lasting clarity.
Frameless windshield wiper blade delivers a sleek beam profile, purpose-built to hold pinpoint wiping accuracy across today’s sculpted windshields. A pre-curved spring-steel beam pairs with a premium silicone edge, ensuring a silent, streak-free sweep. Its wind-cheating contour boosts high-speed stability, while slide-in multi-adapter 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 – buy today.
Bosch Aerotwin – the top series from the trusted German group Bosch. Windshield wipers of this range offer an advanced frameless construction and are supplied to the plants of numerous European vehicle makers. The wiping element is made from a high-tech composite rubber, offering better performance than natural rubber. Spring rails are produced from a special “Evodium” alloy and maintain their original tension throughout the blade’s service life.
