Audi A4 B9/8W PIAA Si-Tech Silicone Wiper (24" / 20")

The PIAA Si-Tech (Silicone Technology) Flat Wiper Blade, a modern, frameless design that delivers all-season performance, thanks to PIAA’s patented silicone impregnated rubber blades. The key to the PIAA Si-Tech’s performance is its frameless design that creates more pressure points across the entire length of the blade for streak-free wiping. Moreover, the design eliminates snow and ice build-up. It is heat and ozone resistant, and its silicone rubber continually reapplies an active silicone coating on the windshield, assuring streak-free, quiet operation.
