Bosch Clear Advantage Wiper Blades offer excellent all-weather performance, featuring a patented beam design that reduces exposed metal for better resistance to ice and snow build-up. The graphite treated, natural rubber wiping edge reduces friction for a quiet and smooth wipe in all seasons. Simple 'Click-On' adapter system makes installation easy on Pin Arm (4.8mm/6.35mm), Hook Arm (9x3mm/9x4mm), Side Lock (22mm), Pinch Tab, Top lock (16mm/19mm), and BMW Top lock wiper arms. A built-in aerodynamic wind spoiler improves airflow while creating additional downforce to hold blade firmly against windshield, preventing blade lift-off. Uniform pressure along the entire blade length applied by the precision-tensioned steel inner spring ensures a smooth, even wipe.
