A frameless wiper that delivers all-season performance by eliminating snow and ice build-up. The Si-Tech's modern design creates more pressure points across the entire length of the blade delivering a streak-free wipe, superior visibility and smooth, chatter-free operation. Plus it features PIAA's patented silicone rubber that continually reapplies an active silicone coating on the windshield, making the windshield water repellent. Rain simply beads up and repels off easily by wind pressure in high speed or by ordinary wiping. Make your driving experience safer with PIAA wiper blades.
