The Bosch Aerotwin AR16U is a single-piece front windshield wiper blade designed for vehicles that use a 400 mm length wiper. It features Bosch's Aerotwin system, which delivers even pressure distribution across the entire blade for consistent wipe performance.

What sets the Bosch Aerotwin AR16U apart
