Wiper Blade Set Bosch Aerotwin A109S

Description

The Bosch Aerotwin A109S wiper blade set includes blades of 550 & 400 mm and boasts a frameless design.
A109S – an all-season set of wipers delivering crystal-clear vision in downpours, sleet, and heat for year-round reliability.

This Bosch A109S wiper blade set boasts an advanced asymmetric deflector, designed to deliver exceptional wipe quality in challenging environments.
An asymmetric spoiler is strategically positioned to channel airflow into targeted downforce 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 demanding high-speed scenarios.
Perfect for performance-driven drivers, this spoiler boosts wipe efficiency for dependable performance.

Frameless wiper blade unleashes a streamlined flat spine, calibrated for pinpoint wiping accuracy across multi-radius glass. A pre-curved spring-steel beam pairs with a premium silicone edge, ensuring a silent, streak-free sweep. Its low-drag aero spoiler boosts high-speed stability, while slide-in multi-adapter suits most makes and models 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.
