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.

    Just buy it

    after experiencing the wind baffling when driving at 45-55mph with the driver side window down, the wind diffuser now has a smooth flow of are around the drivers window up well pass 55mph. I can now drive with the window down and enjoy the weather and sounds. Looks like like factory and installed in less than 10 min with basic tools.
    Great Upgrade

    Great upgrade! Installed on my GT4 in about 10 minutes for each side. Can drive at 75 with passenger window up and no buffeting. Significantly reduced buffeting on the track. I damage the passenger side when installing. Called the manufacturer, sent them a picture and two days later a new one was delivered. Great service!
    My fault, connectors missed

    I purchased a mirror on June 22, 2017. I tried to install it recently, but I found out that the connectors (4 connectors for connecting to 911) were missing. If you don't mind, can I buy only four connectors in the picture?
    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.

    Installed this item two days ago. I was a little hesitant at first as I am not the most mechanical inclined individual, but I can follow directions. Twenty minutes and was done. Looks great and works even better. Love driving with the windows down and hear the tunes.

    Easy to install and they do a very good job reducing the wind noise. As always great service from Suncoast.

    Was very pleased with the results. Able to drive at high speeds and enjoy having the windows down with very little buffeting inside the car. Unless your looking for them you wouldn't notice the change vs the stock window triangle pieces.
    Nice looking pieces, but...

    I ordered this kit hoping my 2012 1/2 991 would be an easy job. When I downloaded the instructions, I discovered that there are Early and Later 991's and that one is easy, the other is much harder, with no way to know until you start taking it apart. I took my car to my dealer and they pulled the inside wing cover as I watched, and it was clear that my car would need to have the door panels completely removed to install these winglets. They estimated $200... per side...to do the work. So I boxed it up and took it home. Sadly for me it was more than 3 weeks from my order date to the dealer visit so I cannot return it (20 day limit). If you have an "early" 991 you are in for a lot of extra expense unless you are comfortable dealing with airbags, and have all the required tools to disassemble the door panels, and the skill to safely put it all back together.
    Works great

    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.
