Presenting the AWE Foiler™ Wind Diffuser. The simple, elegant, and proven solution to wind buffeting in Porsche 991/981/718s. What’s wind buffeting? You know that sound that makes it feel like your head is going to implode when driving your Porsche at speed with one window down? That’s called wind buffeting. It happens when you're moving fast, and it’s quite the issue on the new generations of Porsche Boxster/Cayman and 911. So instead of just letting our brains melt under the pressure of wind buffeting, we did something about it. The AWE Foiler™ Wind Diffuser boasts an unobtrusive yet elegant design. Crafted from UV-stabilized injection-molded plastic, the Foiler™ Wind Diffuser complements Porsche styling without calling unwanted attention. Installation is a breeze with AWE’s user-friendly, bolt-on design. Wind buffeting is defeated, and you can continue to go fast. Passenger and driver's side Foiler™ Wind Diffusers included, as well as all hardware needed for installation. Roll down your window and wave goodbye to wind buffeting.

Installation Instructions
  • UV-stabilized injection-molded plastic for the perfect OE-style look
  • Allows for “single window” down driving without buffeting
  • Combats buffeting, both on the track and on the street
  • Includes driver’s side and passenger side fitments
  • Simple, quick installation
  • Perfect OE-like fitment

Why Drivers Choose FAST of West Chester

  • I can't recommend this place enough. Being able to trust a shop in the performance world is big. The 2hr drive to get there, is worth knowing the job will be done right. Very happy to have found this shop, to
    support my builds going forward.

    Donald Wojnar

  • I recently had the pleasure of working with FAST of West Chester for some performance upgrades on my 2022 WRX, and the experience was nothing short of exceptional. I opted for a Borla S-Type exhaust and Cygnus Coilovers, and the team at FAST nailed the installation, fitment, and setup to a T.

    Adam Cranston

  • The team at FAST are excellence in every way. First, I consulted with Dave on mods for my HPDE track car. He listened and advised me on the best parts & mods to achieve my goals. He was patient & gave me space to research the options presented & worked with me through several changes before we built. Second, the build execution was flawless, proper heat shielding, bracing and poly everywhere. All components worked as advertised.

    Bryce Budd

  • This place has been my go to shop for all things Subaru. From simple service to performance parts and tuning, they have been top notch.

    William Brunell

  • Excellent shop. They installed a Cobb Stage 2 DP and Whiteline Sway bars and end links on my 2013 WRX. The work was done right and clean. The estimate was accurate. They were very knowledgeable, friendly and gave me the straight scoop on exactly what I was getting for the money
    and what I needed to get where I want to be with it. I'd recommend them
    to any car enthusiast.
