Description
The Bosch Aerotwin A991S comes as a frameless construction wiper blade set with 600 and 400 mm blades.
Bosch Aerotwin A991S – an all-weather set of wipers built to handle heavy rain, freezing rain, snowfall, and high temperatures with consistent, long-lasting performance.
This Bosch Aerotwin A991S set of wiper blades integrates an high-performance asymmetric fin, crafted to assure unmatched clarity in diverse weather.
An asymmetric spoiler is strategically positioned to channel airflow into enhanced blade pressure 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 turbulent weather.
Ideal for highway commuters, this spoiler enhances stability for lasting clarity.
Frameless windshield wiper blade offers a streamlined flat spine, calibrated for even line pressure across today’s sculpted windshields. A resilient metal spine pairs with a premium silicone edge, ensuring a whisper-quiet glide. Its low-drag aero spoiler reduces drag, while smart-fit mounting heads 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 – elevate now.
Series Aerotwin – the top series from the respected global group Bosch. Windshield wipers in this line boast an modern frameless construction and are supplied to the assembly lines of numerous European vehicle makers. The wiping element is made from a high-tech composite rubber, offering better performance than natural rubber. Spring elements are produced from a special “Evodium” alloy and maintain their original tension throughout the blade’s service life.
