Wiper Blade Set Bosch Aerotwin A309S

Description

The Bosch Aerotwin A309S wiper blade set includes blades of 650 & 475 mm and features a frameless assembly.
With its weatherproof design, the wiper blade set Bosch Aerotwin A309S guarantees clear visibility from freezing cold to sweltering conditions.

The Bosch Aerotwin A309S wiper blade set incorporates an high-performance asymmetric fin, designed to deliver superior visibility in high-speed scenarios.
An asymmetric spoiler is strategically positioned to channel airflow into focused windshield grip while minimizing drag, applying extra pressure to the wind-facing edge so the blade hugs the glass during gusty conditions. The result is minimal noise and vibration even in turbulent weather.
Tailored for windy climates, it enhances stability for a smoother drive.

Frameless replacement blade delivers a sleek beam profile, precision-engineered to maintain pinpoint wiping accuracy across multi-radius glass. A resilient metal spine pairs with a advanced synthetic-rubber edge, producing a silent, streak-free sweep. Its low-drag aero spoiler boosts high-speed stability, while tool-free quick-click mount 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 series from the trusted global automotive supplier 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, outperforming natural rubber in key properties. Spring strips are produced from a special “Evodium” alloy and maintain their original tension throughout the blade’s service life.
