Bosch 3 397 014 891 (A891S) AeroTwin Front Wiper Blades (Pair)

Under normal driving conditions, Bosch AeroTwin wiper blades should be replaced every 12 to 18 months. Because they feature a patented dual‑synthetic rubber compound and a custom‑contoured Evodium tension spring, they resist UV degradation and extreme weather significantly better than standard conventional blades. You should replace them immediately if you notice streaking, juddering, or unwiped sections on your windscreen.

Yes. Bosch is a leading Original Equipment Manufacturer (OEM) for the world’s top vehicle brands. The A891S AeroTwin blade is an OE‑Equivalent replacement. This means it is engineered to exactly match the factory specifications, aerodynamic profile, and windscreen curvature of the vehicle it was designed for.

Fitting your new blades takes less than a minute. Bosch AeroTwin blades come equipped with a pre‑assembled, vehicle‑specific adapter system. There is no need to swap clips or force parts together. Simply slide the old blade out of the wiper arm, and click the new Bosch adapter into place until you hear a firm 'click'.
Note: Always clean your windscreen thoroughly before fitting new blades.

If a brand‑new set of premium wipers is squeaking, the issue is almost always a contaminated windscreen rather than the blade itself. Road grime, tree sap, and old car‑wash wax create an invisible film that prevents smooth operation.
How to fix it: Clean the glass thoroughly using a dedicated automotive glass cleaner. Wipe down the actual rubber edge of the new blade with a damp cloth to remove any transit dust.
