Wiper Blade Set Bosch Aerotwin A309S

Description

Bosch Aerotwin A309S wiper blade set boasts a frameless assembly and includes 650 + 475 mm blades.
A309S provides enduring, year-round windshield cleaning, thanks to dual blades that effortlessly combat frost, snow buildup, and heavy downpours.

This Bosch A309S set of wipers delivers an asymmetric-style spoiler, designed to deliver reliable performance 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 gusty conditions. The result is reduced lift and chatter even in demanding high-speed scenarios.
Perfect for performance-driven drivers, this spoiler enhances stability for a smoother drive.

Frameless replacement blade delivers a sleek beam profile, precision-engineered to maintain even line pressure across multi-radius glass. 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 smart-fit mounting heads suits 95% of vehicles 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.

Series Bosch Aerotwin – the top series from the renowned European manufacturer Bosch. Wipers of this range boast an advanced 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, outperforming natural rubber in key properties. Spring rails are produced from a special “Evodium” spring steel and maintain their original tension throughout the blade’s service life.
