• Poor visibility in rain, road spray, and seasonal weather changes

Confirm the vehicle’s front wiper configuration before ordering and match the blade length and OE-style profile to the existing setup. This part does not include adapters or quick-connect hardware, so verify that the factory arm connection matches the Bosch Aerotwin design before installation.
