Discovery Channel's "Storm Chasers" clear their windshields with the Bosch Icon™ wiper blades. The Bosch 422 series blades come equipped with dual precision-tensioned springs, a trademarked micro wiping edge, a patented bracket-less wiper blade system and an aerodynamic wind spoiler to help keep the blades from lifting off the windshield during storms or at speed.
The only difference between these wiper blades is where they install on the vehicle. The Bosch 422A installs on the driver side and the Bosch 422B installs on the passenger side.
Bosch developed the first electric windshield wiper system in 1926 and have been manufacturing blades ever since. These blades fit a wide variety of models of domestic and foreign-made vehicles, from Acura, Chevrolet and GMC to Toyota, and many in between.
Made with a special "fx" dual-rubber compound, Bosch blades, according to the manufacturer, provide a flexible soft layer of rubber that reduces chatter on the windshield, while providing better resistance to ice and snow buildup with their bracket-less design.
