Wiper Blade Set Bosch Aerotwin A638S

Description

Bosch Aerotwin A638S comes as a frameless construction set of wipers with 650 and 530 mm blades.
The wiper blade set A638S offers uninterrupted, all-weather performance for both blades in rain, snow, and extreme heat.

This Bosch A638S set of wiper blades offers an asymmetric-style spoiler, engineered for superior visibility in all conditions.
An asymmetric spoiler is strategically positioned to channel airflow into enhanced blade pressure while reducing aerodynamic resistance, 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 turbulent weather.
Tailored for windy climates, it enhances stability for a smoother drive.

Frameless replacement blade offers a sleek beam profile, purpose-built to hold pinpoint wiping accuracy across complex windshield curves. A pre-curved spring-steel beam pairs with a premium silicone edge, producing a whisper-quiet glide. Its low-drag aero spoiler boosts high-speed stability, while slide-in multi-adapter 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). Go beam, drive clear – buy today.

Series Bosch Aerotwin – the premium series from the respected global automotive supplier Bosch. Wipers in the Aerotwin family boast an advanced frameless construction and are supplied to the plants of numerous 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.
