Description
This 650 and 575 mm set of wipers Bosch Aerotwin AR991S is built with a frameless assembly.
AR991S – an all-weather wiper blade set built to handle rain, freezing rain, snow, and high temperatures with consistent, long-lasting performance.
This Bosch AR991S set of wipers boasts an asymmetric spoiler, designed to deliver exceptional wipe quality in diverse weather.
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 minimal noise and vibration even in turbulent weather.
Tailored for windy climates, it boosts wipe efficiency for dependable performance.
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 advanced synthetic-rubber edge, ensuring a crystal-clear pass. Its wind-cheating contour cuts lift at highway speed, while tool-free quick-click mount suits 95% of vehicles for rapid installation. 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.
Bosch Aerotwin – the flagship series from the renowned European automotive supplier Bosch. Wipers in this line boast an advanced frameless construction and are supplied to the plants of numerous leading vehicle makers. The wiping element is made from a multi-compound rubber, outperforming natural rubber in key properties. Spring rails are produced from a special “Evodium” alloy and maintain their original tension throughout the blade’s service life.
