Wiper Blade Set Bosch Aerotwin A843S

Description

Bosch Aerotwin A843S – frameless wiper blade set, 550 and 550 mm for comprehensive coverage.
Elevate exceptional clarity year-round with the A843S two-pack wiper blades — crafted to fight off heavy rain, freezing rain, snowfall, and blazing sun effortlessly.

This Bosch A843S set of wiper blades showcases an high-performance asymmetric fin, crafted to ensure exceptional wipe quality in diverse weather.
An asymmetric spoiler is strategically positioned to channel airflow into targeted downforce while reducing aerodynamic resistance, applying extra pressure to the wind-facing edge so the blade hugs the glass during gusty conditions. The result is a crystal-clear wipe even in turbulent weather.
Tailored for windy climates, this spoiler boosts wipe efficiency for a smoother drive.

Frameless replacement blade offers a sleek beam profile, precision-engineered to maintain even line pressure across multi-radius glass. A resilient metal spine pairs with a premium silicone 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 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.
