You know that sound that happens when your window is down at speed that makes it feel like your head is going to implode? That’s called wind buffeting. It happens when you’re moving fast, and it’s quite the issue on the newest generation of Porsche Boxster, Cayman, and 911 Carrera models.

Made by AWE Tuning, this diffuser boasts an unobtrusive yet elegant design. Crafted from UV stabilized injection-molded plastic, it complements Porsche styling without calling unwanted attention. Once installed, driving with the windows open will be more comfortable and more quiet. A simple solution to a common gripe among Porsche owners.

    Can you say 10,000% profit margin? Yea, they work, but WAY WAY WAY overpriced. These should be a $12 item, tops.
    Works - but quality lacking

    Ok - install was ok - not that complex - but only 2 small screws - easily will drop in the door panel. They are very thin plastic and not sure how they are going to hold up. They do lower the impact of the reverb of the air at higher speeds. For almost 100 these are overpriced.
    Not helpful if you have a cabriolet

    I was hoping these would cut back on the buffeting with the top down, but windows up. It did not seem to make much of a difference. The installation was simple.
    Worth it! Installation easy on the second door;)

    What most other reviewers said about effectiveness, to wit: buffeting gone, fit/finish very good (one poster mentioned a gap but check your stock triangles before removal and you'll see the oem's have the same gap), worth it. For early 991's , installation isn't hard but it's not plug/play like on newer 911's. Getting the four plastic trip pieces and four bolts off is a breeze after you've done it once. Removing and reinstalling the door is also simple once you've done it once. My only caveat is to make sure you fully connect the blue multiprong door plug before reinstalling the door. There's a little purple plastic hinge that kind of ensures it's fully pushed in, but the first time I did it none of my door/window functions worked. Took door off again and saw that I hadn't pushed the blue plug in all the way. Once it's in, you'll know it by how far in it goes. I could now install two AWE's diffusers in under 10 mins per side. If you're in the Bay Area and want to avoid the learning curve on an early 991.1 (i.e., door removal required), drop by and I'll help you out!

    They really do work

    Completely worth the price, they almost completely remove all buffeting at any speed when the passenger window is closed and the driver's window is open. Unless you have a very early 981, the install takes 5-10 minutes per side, and if you do it right, anyone will think they are OEM. Too bad Porsche doesn't install them from the factory.

    I know what your thinking $80 for two pieces of plastic, but I can tell you they really do work. If you want to get rid of the wind buffeting and drive with one or two windows open at any speed this is the only way to do it. I have a 991.1 and before the wind diffusers I needed to open the sunroof with the windows open. They fit well also.

    Pretty straightforward easy installation and they do lessen the wind buffeting at speed...but way over priced for what they are. Should be no more than $50
    Works

    I was a bit skeptical. However, it works well. Easy install. It should be a factory OEM option. When I track my 991.2 GT3 they require windows down. The buffeting was intolerable until now. Highly recommend.
    They work

    Installation easy. Passenger side fits good but not as well as the driver's side. Cuts out wind issues especially at HPDE events.
    Ok but not great
    (Calgary) | May 30th, 2020
    Plastic feels flimsy compared to OEM. Fit was good on driver side, but there is a bigger gap on the passenger side. Installation is very easy. It does reduce buffeting at highway speeds. But, when the widows are up I can now hear a whistling noise. It's not loud but still audible. TBH I'm not sure I'll keep these on or not.
