Wiper Blade Set Bosch Aerotwin RLE A399S

Description

Bosch Aerotwin RLE A399S – set of wipers developed using frameless construction, lengths 450 mm & 600 mm.
Bosch Aerotwin RLE A399S – an all-season set of wipers delivering crystal-clear vision in rain, snow, and extreme temperatures for year-round reliability.

The Bosch Aerotwin RLE A399S set of wiper blades features an asymmetric spoiler, engineered for exceptional wipe quality in challenging environments.
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 rapid commutes. The result is a crystal-clear wipe even in turbulent weather.
Perfect for performance-driven drivers, this spoiler enhances stability for a smoother drive.

Frameless windshield wiper blade delivers a streamlined flat spine, purpose-built to hold pinpoint wiping accuracy across multi-radius glass. A resilient metal spine pairs with a premium silicone edge, producing a whisper-quiet glide. Its wind-cheating contour boosts high-speed stability, 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). Experience silent clarity – take your drive to the next level now.
