Wiper Blade Set Bosch Aerotwin A420S

Description

This 575 / 380 mm Wiper Blade Set Bosch Aerotwin A420S features a frameless assembly.
Engineered for all-season use, the set of wipers Bosch Aerotwin A420S maintains optimal contact and smudge-free cleaning across both blades in any weather.

This Bosch Aerotwin A420S set of wipers boasts an high-performance asymmetric fin, designed to deliver superior visibility in diverse weather.
An asymmetric spoiler is strategically positioned to channel airflow into targeted downforce while minimizing drag, applying extra pressure to the wind-facing edge so the blade hugs the glass during gusty conditions. The result is a streak-free visibility even in strong crosswinds.
Tailored for windy climates, it boosts wipe efficiency for a smoother drive.

Frameless replacement blade offers a modern tensioned beam, precision-engineered to maintain constant glass contact across multi-radius glass. A resilient metal spine pairs with a premium silicone edge, producing a silent, streak-free sweep. Its low-drag aero spoiler reduces drag, while slide-in multi-adapter 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). Experience silent clarity – elevate now.
