Wiper Blade Set Bosch Aerotwin AR991S

Description

Bosch Aerotwin AR991S – frameless set of wipers, 650 mm / 575 mm for clear visibility.
Tackle every season head-on—the AR991S two-pack wiper blades offers weather-resistant construction, ensuring spotless visibility in any condition.

The Bosch AR991S set of wipers boasts an asymmetric spoiler, built to provide unmatched clarity in all conditions.
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 reduced lift and chatter even in turbulent weather.
Tailored for windy climates, it boosts wipe efficiency for lasting clarity.

Frameless windshield wiper blade delivers a modern tensioned beam, precision-engineered to maintain constant glass contact across multi-radius glass. A resilient metal spine pairs with a advanced synthetic-rubber edge, producing a whisper-quiet glide. Its low-drag aero spoiler reduces drag, while tool-free quick-click mount 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 – get today.
