i dont know about the Piaa's but Bosch wiperblade in certs are really good blades, we have them on the celica, and our camry...they so much better, and dont heat up like the stock ones under direct summer sun light.
Once you see the difference, you'll never go back. Silicone blades work so much better at wiping away the water. And after time, the stock ones you have will wear.. just give it time, you'll see what I mean.
