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.

    Worth it

    A little pricey for two pieces of plastic but they work. Took just a small amount of finish work to get them to fit perfectly. Had to remove the door panel to install but not difficult and worth the extra effort.

    I received the items in a reasonable amount of time and was accurately filled. Thanks Suncoast. Installation was straight forward, however the company should have included the interior trim tool which would be inexpensive. In the instructions it stated there maybe a gap once installed due to different applications, however the gap was very uneven and varied from side to side. Because of this it doesn't look like an OEM piece. I haven't been able to test its effectiveness but assume it'll work just fine based on the previous reviews.
    A useful upgrade, but installation can be tricky

    These work well. But, depending on the model/build of the Boxster you have, they can be tricky to install. Suncoast supplies directions, but I had to have mine installed by by my mechanic.

    Not inexpensive , but effective! Easy to install on my 2015 Cayman GTS. Cuts buffeting by at least 80%. It's a pleasure to drive at 70+mph again with the window(s) down.
