Will the Top Secret GT-R M17 Aero Bonnet fit if I don't install the M17 front bumper kit?

Yes, the Aero Bonnet mounts on CBA, DBA, and EBA R35 GT-R models without the M17 front bumper kit. On chassis built before the V-motion update, though, running it alone leaves the hood's press lines out of step with the factory grille. Top Secret recommends pairing it with the kit so the lines read correctly front to back.

Why doesn't the stock R35 hood work with the M17 bumper kit?

The factory hood on earlier R35 GT-R chassis was designed before Nissan introduced the V-motion grille with the M17 facelift kit. The stock press lines don't follow that shape, so bolting the M17 bumper on without this Aero Bonnet leaves a visible mismatch between hood and grille.

Does the Aero Bonnet include a rain guard?

Yes, every Top Secret GT-R M17 Aero Bonnet ships with a rain guard for wet-weather driving. It's sold as a single hood panel; the M17 full bumper kit is a separate purchase and is not included.

What do the ducts on the Aero Bonnet actually do?

The ducts on the Top Secret Aero Bonnet are placed to pull heat out of the engine bay during sustained high-load driving, like repeated track sessions. Better heat dissipation under the hood helps protect components exposed to elevated temperatures on a GT-R pushed hard on circuit.

Description

Top Secret Aero Bonnet for R35 Nissan GT-R (2008-2023)

Nissan’s M17 facelift kit brought the V-motion grille to the R35 GT-R, and the Top Secret GT-R M17 aero bonnet so CBA, DBA, EBA, and 4BA chassis can run that front-end look without the hood’s press lines fighting the new grille shape. Beyond the styling fix, the bonnet is built for how these cars actually get driven. Ducting is placed to pull heat out of the engine bay during sustained high-load runs, which is where a GT-R doing repeat track sessions puts more strain on the engine bay than one doing weekend cruises. A rain guard is included for regular street use. The panel is available in FRP with a carbon fiber NACA duct section, or in full carbon fiber for a lighter build.

Features

Press lines traced through the V-motion grille shape from the M17 facelift
Ducting placed to move heat off the engine bay
Rain guard included
Choice of FRP with a carbon fiber NACA duct section, or full carbon construction

Nissan GT-R: CBA-R35, DBA-R35, EBA-R35, 4BA-R35 | 2008-2023

Notes

Not compatible on 2024-2025 facelift EBA GT-R models
If installed alone on a CBA or DBA (2008-2016) model, the hood’s press lines will not fully align with the factory grille shape unless installed alongside the Top Secret M17 front bumper kit
All FRP is delivered unpainted, and all Top Secret carbon is delivered in its raw state and will require prep and application of a UV resistant clear coat and/or PPF

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.
