The PIAA Si-Tech (Silicone Technology) Flat Wiper Blade is an all-season, durable wiper blade that incorporates PIAA's patented silicone rubber. 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 and greatly reduced ice and snow build-up.

The wiper design and blade compound ensure even greater visibility by coating the windshield with silicone to promote continuous water beading in inclement weather. Water beads up into droplets at low speeds that are easily removed by ordinary wiping. And at higher speeds, wind pressure pushes the water off the windshield, often without even requiring wiper use. The silicone coating also reduces drag and eliminates annoying and inefficient chattering and squeaking, regardless of the shape of the windshield, to provide greater comfort for both driver and passenger. And the best part: the PIAA Si-Tech Flat Wiper Blades reapply the silicone coating every time the wipers are used.

PIAA wiper blades maintain a sharp, clean edge and offer better resistance to all climates (heat, ozone, ultra-violet) - clearly outperforming the industry standard rubber blade.

In order to accommodate a wide range of wiper attachment methods, the PIAA Si-Tech wiper comes complete with two wiper arm adapters. Simply select the correct adapter for your vehicle and attach as shown.

    Hard to figure which clips to use on the news wiper blade. It took me awhile to figure the correct clips to use on the new wiper blades and from there, it was pretty much easy to install.

    Could’ve saved a bunch of money by purchasing rain-x blades. They’re just as good. Also, the K4 uses a standard j-hook blade so any wiper blade will work. Ignore the compatibility advice on the website because it’ll state that most wiper blades will not work.
