Wiper Blade Set Bosch Aerotwin A420S

Description

The Bosch Aerotwin A420S set of wipers comes with frameless design and includes 575 & 380 mm blades.
Built for every season, the set of wipers A420S stands up to harsh weather and deicing chemicals to keep your view perfectly clear.

This Bosch A420S wiper blade set features an high-performance asymmetric fin, designed to deliver 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 a smudge-free wipe even in demanding high-speed scenarios.
Tailored for windy climates, it enhances stability for lasting clarity.

Frameless wiper blade delivers a modern tensioned beam, calibrated for pinpoint wiping accuracy across multi-radius glass. A resilient metal spine pairs with a premium silicone edge, producing a crystal-clear pass. Its wind-cheating contour reduces drag, 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.
