Bosch Aerotwin A843S is a front wiper blade set featuring the dual-blade Aerotwin design with an integrated aerodynamic spoiler that keeps the blade pressed evenly against the glass at speed, reducing lift, streaking, and wind noise. The set includes both driver and passenger side blades with OE-style quick-release adapters for a direct bolt-on fit.

Fitment: Mercedes-Benz C-Class (W205/S205) and GLC-Class (X253/C253), front axle application, matching the source chassis range (W205, C253, X253).
