## Description

Bosch Clear Advantage Wiper Blades feature a patented beam design that reduces exposed metal for greater resistance to ice and snow build-up for improved all-weather performance. The blended natural rubber blade, with graphite treated wiping edge, reduces friction for a quiet and smooth wipe in all seasons. Clear Advantage wiper blades include an aerodynamic wind spoiler that creates downward force which ensures superior windshield contact for consistent wiping at higher speeds. The versatile Click-On adapter system - compatible with most vehicles - ensures quick and easy installation. Included adapters fit: 9x3mm Hook, 9x4mm Hook, 4.8mm (3/16 inch) Small Pin, 6.35mm (1/4 inch) Large Pin, Side Lock, 16mm Narrow Top Lock (select lengths only), 19mm Large Top Lock, BMW Top Lock, Pinch Tab.

Review: My car loves them - This wiper blade works great and gives a clean, streak free wipe. It fits perfectly and installs quickly with no hassle. The beam design keeps consistent pressure across the windshield, even in heavier rain. It runs quietly and handles water really well. Solid quality from Bosch and a noticeable upgrade over standard blades. Would definitely buy again.
Review: Fit driver's side on our Subaru 2023 Outback. - As described. Easy to install once you correctly determine the type of wiper arm you have. They work very well. Happy with the purchase.
