Bosch Aerotwin Wiper Blade Set A173S – Dacia Sandero II Facelift (2016–2020) 550/475mm

Bosch Aerotwin A173S Wiper Blade Set – Dacia Sandero II Facelift (2016–2020)

⚠️ ATTENTION – Strict compatibility by year of manufacture: This set is exclusively compatible with Dacia Sandero II Facelift manufactured between 2016 – 2020, factory-equipped with Bayonet (slide-on) attachment. Sandero II models produced before 2016 (2012–2015) have J-Hook attachment and are NOT compatible. Sandero III (from 2021) uses VATL/Clips attachment and is not compatible.

Bosch Aerotwin A173S (long code: 3397014173) represents the premium standard in automotive wiper blades. The package contains two jointless blades with an integrated spoiler: 550 mm for the driver and 475 mm for the passenger, with factory pre-installed Bayonet adapters.

Why is Bosch Aerotwin different from any other wiper?

1. Jointless Technology

A173S is a single piece — two elastic Evodium premium steel rails, pre-tensioned to the curvature of the Sandero's windshield. Equal pressure on every millimeter, from -20°C to +40°C. Does not freeze in winter.

2. Twin Technology (Two Rubber Compounds)

The ultra-flexible base ensures smooth articulation. The wiping lip treated with graphite and Teflon — eliminates squeaking and resists concentrated windshield washer fluids.

3. Integrated Aerodynamic Spoiler

The faster you go, the harder the airflow presses the wiper against the windshield. The wind becomes your ally.

4. Factory-Integrated Bayonet Attachment

Adapter molded directly into the metal structure — no play, no vibration, no risk of detaching from the arm at 130 km/h.
