Vehicles with metal bow windscreen wipers and so-called conventional hook wiper arms can also be retrofitted with Aerotwin flat blade wipers. The upgrade program includes the Aerotwin with pre-assembled adapter: simply hook it in, snap it in, and it's ready to go. Perfect wiping performance at every point of the windscreen thanks to high-tech spring rail and aerodynamically optimised profile. Minimal wind noise due to less airflow attack surface. Improved winter suitability, as ice cannot freeze on metal frames and joints. Easy wiper change due to pre-mounted adapter for vehicles with hook wiper arms. Innovative design. Integrated aerodynamic spoiler. Longer service life. Uniform wear due to uniform contact pressure. Particularly resistant to insects and stubborn dirt.
