Description
Bosch Aerotwin A420S – frameless wiper blade set, 575 & 380 mm for maximum reach.
Experience crystal-clear visibility year-round with the A420S set of two all-weather wipers — built to fight off downpours, icy sleet, snow flurries, and scorching heat for nonstop performance.
The Bosch A420S set of wiper blades showcases an advanced asymmetric deflector, optimized for robust performance in high-speed scenarios.
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 a crystal-clear wipe even in strong crosswinds.
Perfect for performance-driven drivers, this spoiler enhances stability for lasting clarity.
Frameless windshield wiper blade delivers a modern tensioned beam, purpose-built to hold constant glass contact across complex windshield curves. A pre-curved spring-steel beam pairs with a advanced synthetic-rubber edge, producing a crystal-clear pass. Its wind-cheating contour boosts high-speed stability, while smart-fit mounting heads 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). Experience silent clarity – take your drive to the next level now.
