Wiper Blade Set Bosch Aerotwin A109S

Description

This 550 & 400 mm Wiper Blade Set Bosch Aerotwin A109S features a frameless assembly.
Bosch Aerotwin A109S – an all-season set of wipers delivering crystal-clear vision in rain, snow, and extreme temperatures for round-the-clock reliability.

This Bosch Aerotwin A109S set of wipers showcases an asymmetric spoiler, crafted to guarantee exceptional wipe quality in diverse weather.
An asymmetric spoiler is strategically positioned to channel airflow into focused windshield grip while reducing aerodynamic resistance, applying extra pressure to the wind-facing edge so the blade hugs the glass during fast-paced drives. The result is a crystal-clear visibility even in strong crosswinds.
Tailored for windy climates, this spoiler enhances stability for lasting clarity.

Frameless replacement blade delivers a sleek beam profile, calibrated for constant glass contact across today’s sculpted windshields. A resilient metal spine pairs with a premium silicone edge, ensuring a whisper-quiet glide. Its wind-cheating contour boosts high-speed stability, while slide-in multi-adapter 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). Go beam, drive clear – buy today.

Aerotwin – the premium series from the renowned European automotive supplier Bosch. Wiper blades in this line boast an advanced frameless construction and are supplied to the assembly lines of numerous 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.
