Description
The Bosch Aerotwin A851S set of wipers includes blades of 600 + 450 mm and boasts a frameless assembly.
A 851 S delivers universal, round-the-year durability—dual blades clearing away sleet, blizzard conditions, and road debris for a clear windshield on every drive.
The Bosch A 851 S wiper blade set features an asymmetric-style spoiler, crafted to guarantee superior visibility in high-speed scenarios.
An asymmetric spoiler is strategically positioned to channel airflow into targeted downforce while reducing aerodynamic resistance, 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.
Tailored for windy climates, it enhances stability for dependable performance.
Frameless replacement blade unleashes a modern tensioned beam, purpose-built to hold even line pressure across today’s sculpted windshields. A resilient metal spine pairs with a advanced synthetic-rubber edge, ensuring a crystal-clear pass. 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). Experience silent clarity – elevate now.
Aerotwin – the flagship line from the renowned German group Bosch. Wipers in the Aerotwin family offer an modern frameless construction and are supplied to the plants of many European vehicle makers. The wiping element is made from a multi-compound rubber, offering better performance than natural rubber. Spring rails are produced from a special “Evodium” alloy and preserve their original tension throughout the blade’s service life.
