Description
Bosch Aerotwin A392S – wiper blade set featuring frameless assembly, lengths 700 mm & 575 mm.
A392S provides dependable, year-round windshield cleaning, thanks to dual blades that effortlessly combat frost, snow buildup, and rainstorms.
This Bosch A392S wiper blade set offers an asymmetric spoiler, crafted to ensure superior visibility 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 fast-paced drives. The result is a smudge-free wipe even in turbulent weather.
Perfect for performance-driven drivers, this spoiler boosts wipe efficiency for dependable performance.
Frameless wiper blade delivers a sleek beam profile, calibrated for even line pressure across complex windshield curves. A pre-curved spring-steel beam pairs with a advanced synthetic-rubber edge, ensuring a silent, streak-free sweep. Its low-drag aero spoiler cuts lift at highway speed, while tool-free quick-click mount 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). Experience silent clarity – upgrade now.
