I bought the Heko wind deflectors for the Alfa Romeo Giulietta, since a few years earlier I had also bought them for the Alfa Romeo 147 and they fit perfectly (with more double-sided tape and more clips) and are still in excellent condition. However, the wind deflectors for the Giulietta did not go well, as they do not fit at all! They are much larger than all four windows. They do not fit at all lengthwise, so I tried very carefully to shorten the "lip" around the wind deflector. I had to cut and file more than 2 centimeters front and back, with the result that I reached the visible part (the curve). They eventually fit, but they did not sit properly, as they cut into the vertical window rubber on the driver’s and rear windows. I could not fit the passenger-side one and in the end I ruined it.... Also, even with the wind deflectors cut, the windows would not close all the way; the window would go down. I will try again by buying another brand. Unacceptable for one of the best companies in wind deflectors. I understand that I damaged them in order to make them fit/install, but I still have them and can send them for inspection if requested.
