What is wind buffeting, and does the AWE Foiler™ Wind Diffuser actually fix it on the GR Supra?

Wind buffeting is the low-frequency thumping or pressure sensation that builds inside the cabin when driving at speed with one window down. On the GR Supra it is particularly noticeable and can make open-window driving genuinely uncomfortable. The AWE Foiler™ Wind Diffuser is a platform-specific solution designed to redirect airflow at the door opening, eliminating that pressure buildup. AWE tested and confirmed it works at speeds up to 130mph with windows up or down, on the street and at the track.

Will the AWE Foiler™ Wind Diffuser fit the 2.0L four-cylinder A90 GR Supra?

Yes. The AWE Foiler™ Wind Diffuser fits all A90 and A91 GR Supra models from 2020 through 2025, covering both the 3.0L and 2.0L applications. The set includes both driver and passenger side Foilers with die-cut adhesive, and fitment is backed by AWE's Perfect Fitment guarantee.

How is the AWE Foiler™ Wind Diffuser installed, and will it damage the paint on my GR Supra?

Installation is straightforward; the Foilers attach via included die-cut 3M adhesive pads that are contoured specifically for the recessed base of the Foiler. No drilling, no modification, and no tools required. The recessed base is designed to accommodate the adhesive thickness for a flush, clean fit. For best adhesion, clean and degrease the mounting surface thoroughly before applying.

Does the AWE Foiler™ Wind Diffuser introduce any wind whistle on the GR Supra with windows up?

No, and that was a specific design goal. AWE's earlier Foiler™ designs for other platforms were found to introduce a wind whistle with windows up on the GR Supra during in-house testing, so AWE built a completely new, platform-specific design for the A90/A91. The result addresses both problems; no buffeting with windows down, and no whistle with windows up, confirmed up to 130mph.

AWE Tuning Foiler Wind Diffuser for A90/A91 Toyota GR Supra

The AWE Foiler™ Wind Diffuser for the GR Supra is a bespoke design built from the ground up for this platform; not a carryover from previous iterations. AWE’s earlier Foiler™ designs, originating on Porsche 991 models, worked well for those platforms, but testing on the GR Supra revealed that designs following that same approach introduced a wind whistle with windows up while solving buffeting with windows down. AWE addressed both problems at once with a platform-specific design that eliminates buffeting with the windows down and avoids introducing whistle with them up, tested and confirmed up to 130mph. The result is a clean, unobtrusive profile that mirrors the existing mirror trim and looks factory from every angle; no carbon weave, no oversized wings, and none of the premium markup that comes with other options on the market. Installation is a matter of peeling and sticking the included die-cut adhesive, and the recessed base ensures a flush, secure fit from day one.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
