Detailed Product Overview

Bosch 3397014206 is part of the OE Style Blade line, a product line focused on factory-style replacement fitment and straightforward installation on supported vehicles. This Bosch Aerotwin Wiper Blade uses a beam-style profile rather than a traditional framed design, which helps maintain even pressure along the windshield for consistent wiping performance. The all-season EPDM blade material is selected for everyday driving conditions, while the attached spoiler/aerofoil supports stable operation during highway use.
