Wiper Blade Set Bosch Aerotwin A404S

Description

Bosch Aerotwin A404S wiper blade set comes with frameless assembly and includes 700 / 340 mm blades.
Built for every season, the wiper blade set A404S stands up to harsh weather and deicing chemicals to keep your view perfectly clear.

This Bosch A404S wiper blade set offers an asymmetric spoiler, built to provide unmatched clarity in challenging environments.
An asymmetric spoiler is strategically positioned to channel airflow into enhanced blade pressure while minimizing drag, applying extra pressure to the wind-facing edge so the blade hugs the glass during highway speeds. The result is reduced lift and chatter even in turbulent weather.
Tailored for windy climates, this spoiler enhances stability for dependable performance.

Frameless wiper blade offers a modern tensioned beam, calibrated for even line pressure across multi-radius glass. A pre-curved spring-steel beam pairs with a premium silicone edge, producing a silent, streak-free sweep. Its low-drag aero spoiler cuts lift at highway speed, 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.

Aerotwin – the flagship line from the trusted European manufacturer Bosch. Windshield wipers in this line offer an advanced frameless construction and are supplied to the assembly lines of many 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 maintain their original tension throughout the blade’s service life.
