Bosch ICON blades use exclusive tension spring arcing technology to create a fit that is custom-contoured to the curvature of each side of the windshield. The correct blade for a particular vehicle is based on a combination of the blade length and the curvature of the windshield. Driver side always has an “A” part number. Passenger side can have an “A” or “B” part number depending on the vehicle. Blades with a “B” part number have a greater curvature specifically designed to wrap around the passenger side window for greater visibility and clarity. Bosch continues its innovation and leadership with the ICON OE Multi-Clip connector, which offers a like-for-like OE replacement. The Multi-Clip features a flexible connector system, simplifying the installation process for all types of vehicles. Reference the Bosch Wiper Blade catalogue or ask your auto parts professional for the exact part numbers for your vehicle.
