Wiper Blade Set Bosch Aerotwin RLE A399S

Description

Bosch Aerotwin RLE A399S – set of wipers featuring frameless assembly, lengths 450 mm & 600 mm.
With its weather-resistant construction, the set of wipers A399S guarantees clear visibility from sub-zero temperatures to sweltering conditions.

The Bosch A399S set of wiper blades showcases an advanced asymmetric deflector, built to provide unmatched clarity in all conditions.
An asymmetric spoiler is strategically positioned to channel airflow into optimal contact force while minimizing drag, applying extra pressure to the wind-facing edge so the blade hugs the glass during gusty conditions. The result is minimal noise and vibration even in strong crosswinds.
Perfect for performance-driven drivers, it enhances stability for lasting clarity.

Frameless replacement blade delivers a sleek beam profile, calibrated for constant glass contact across today’s sculpted windshields. A resilient metal spine pairs with a premium silicone edge, producing a whisper-quiet glide. Its low-drag aero spoiler cuts lift at highway speed, while tool-free quick-click mount 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 – shop today.
