Description
Bosch Aerotwin A004J – frameless wiper blade set, 650 + 600 mm for full-span coverage.
A004J – an year-round wiper blade set delivering crystal-clear vision in downpours, snow, and heat for year-round reliability.
This Bosch A004J set of wipers boasts an asymmetric-style spoiler, built to provide superior visibility in diverse weather.
An asymmetric spoiler is strategically positioned to channel airflow into enhanced blade pressure while minimizing drag, applying extra pressure to the wind-facing edge so the blade hugs the glass during rapid commutes. The result is a crystal-clear visibility even in turbulent weather.
Tailored for windy climates, it enhances stability for a smoother drive.
Frameless replacement blade delivers a modern tensioned beam, calibrated for pinpoint wiping accuracy across today’s sculpted windshields. A resilient metal spine pairs with a advanced synthetic-rubber edge, producing a whisper-quiet glide. Its low-drag aero spoiler cuts lift at highway speed, while slide-in multi-adapter suits most makes and models 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 – take your drive to the next level now.
Series Bosch Aerotwin – the flagship series from the trusted German automotive supplier Bosch. Windshield wipers in this line boast an advanced frameless construction and are supplied to the production lines of numerous European vehicle makers. The wiping element is made from a high-tech composite rubber, outperforming natural rubber in key properties. Spring strips are produced from a special “Evodium” spring steel and maintain their original tension throughout the blade’s service life.
