The Bosch Aerotwin AR550S windshield wiper is a modern flat blade wiper that is particularly suitable for retrofitting older vehicle models such as Audi, Ford, or Dodge. Compared to conventional bracket wipers, the latest flat blade technology is significantly superior. The bracketless flat blade wipers operate without any joints, as their spring rails are individually tailored to the geometry of the windshield for each vehicle type. This ensures optimal wiping performance.
