Both the Toyota GR Supra and the BMW Z4 are fantastic representations of modern 2-seater sports coupes, designed to bring you pure driving joy in a sleek and stylish package. With their bold, flowing lines, these cars make a statement that's hard to ignore, almost to the point of being daring. However, this striking exterior doesn't quite carry over to the driving experience or engine sounds, which can feel a bit underwhelming. Take the factory air box, for instance—while it gets the job done, it leaves a lot to be desired in terms of airflow and performance. Plus, it includes an intake resonator that mutes those thrilling turbo and intake sounds that performance enthusiasts crave.

Enter the Dinan carbon fiber intake, which addresses these shortcomings head-on. This intake system is designed to flow a whopping 58% more air than the stock setup, leading to snappier throttle response and a noticeable boost in power. It also removes the intake resonator, allowing those exhilarating sounds to shine through. If you're considering upgrading to a high-powered build—think upgraded turbo and fueling—this intake is a game-changer that won’t hold you back.

To achieve this impressive airflow, Dinan has reimagined the entire lower box of the intake system, not just the lid. This redesign maximizes the available space in the engine bay, accommodating a 40% larger, custom, free-flowing filter. Dinan’s engineers also wanted to add a secondary inlet to fully utilize the expanded air box and filter surface area. They conducted extensive testing on various shapes, sizes, and locations for this inlet to ensure it wouldn’t inadvertently raise air temperatures—something that can be a common issue with open-air intakes. The final design features carefully patterned openings on the opposite side from the engine, striking the perfect balance between increased volume and maintaining optimal turbo inlet temperatures, no matter the driving conditions.

With the added airflow, you can expect improved throttle response and a max gain of +13 WHP and +14 lb-ft of torque on a completely stock vehicle. If you’re already working with a modified setup, the Dinan intake will help you push the limits of your power potential even further. For those looking to build a more powerful and robust system, complete with turbo and fueling upgrades, this intake ensures you won’t hit any roadblocks. Plus, the secondary air inlets and sound slot on the lid make the intake system more audible, letting you truly appreciate the turbo spool and blow-off valve sounds—quite a contrast from Dinan's traditional sealed systems, where those sounds tend to be muffled.

And let’s not forget about aesthetics! The Dinan intake system is crafted from stunning 2x2 gloss twill carbon fiber, enhancing the visual appeal under the hood. Paired with aluminum Dinan strut braces and a matching carbon fiber engine cover, your engine bay will be just as eye-catching as the exterior of your vehicle. It’s a cohesive style that combines performance with a touch of flair.
