Wiper Blade Set Bosch Aerotwin A109S

Description

The Bosch Aerotwin A109S set of wipers includes blades of 550 / 400 mm and boasts a frameless design.
Engineered for year-round use, the wiper blade set A109S maintains perfect contact and clear wiping across both blades in any climate.

The Bosch A109S wiper blade set showcases an asymmetric spoiler, engineered for exceptional wipe quality in challenging environments.
An asymmetric spoiler is strategically positioned to channel airflow into optimal contact force while minimizing drag, applying extra pressure to the wind-facing edge so the blade hugs the glass during rapid commutes. The result is minimal noise and vibration even in demanding high-speed scenarios.
Tailored for windy climates, this spoiler boosts wipe efficiency for dependable performance.

Frameless replacement blade offers a streamlined flat spine, calibrated for constant glass contact across today’s sculpted windshields. A resilient metal spine pairs with a advanced synthetic-rubber edge, producing a crystal-clear pass. Its wind-cheating contour cuts lift at highway speed, while smart-fit mounting heads 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). Experience silent clarity – upgrade now.
