Wiper Blade Set Bosch Aerotwin A638S

Description

Bosch Aerotwin A638S – wiper blade set blades of 650 mm + 530 mm, featuring a frameless construction.
Engineered for year-round use, the wiper blade set A638S maintains optimal contact and crystal-clear wiping across both blades in any climate.

The Bosch A638S set of wipers incorporates an high-performance asymmetric fin, built to provide exceptional wipe quality in challenging environments.
An asymmetric spoiler is strategically positioned to channel airflow into optimal contact force while reducing aerodynamic resistance, 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 strong crosswinds.
Tailored for windy climates, it boosts wipe efficiency for dependable performance.

Frameless wiper blade delivers a sleek beam profile, precision-engineered to maintain pinpoint wiping accuracy across complex windshield curves. A pre-curved spring-steel beam pairs with a advanced synthetic-rubber edge, producing a silent, streak-free sweep. Its low-drag aero spoiler cuts lift at highway speed, while smart-fit mounting heads 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). Go beam, drive clear – order today.

Bosch Aerotwin – the top series from the respected European automotive supplier Bosch. Windshield wipers in this line feature an modern 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 elements are produced from a special “Evodium” alloy and preserve their original tension throughout the blade’s service life.
