Which vehicles does the Eventuri Carbon Intake System fit?

The Eventuri Carbon Intake System fits the 4.0T twin-turbo V8, covering the Audi RSQ8 (2020-2026), Audi SQ7 and SQ8 (2020-2024), Lamborghini Urus (2019-2024), Porsche Cayenne Turbo (2020-2024), and Bentley Bentayga (2019-2024). It is not compatible with models using electronic wastegates, so confirm your intake configuration before ordering.

How much power does it add?

Eventuri's published figures show gains of 14 to 20 hp and 17 to 21 lb-ft on a stock tune, rising to 25 to 28 hp and 20 to 23 lb-ft at Stage 1. An independent dyno test by Eurocharged Canada confirmed consistent gains across a broad rpm range. Actual results vary with your ECU calibration and supporting mods.

What makes this intake different from the factory setup?

Eventuri redesigned the full inlet tract rather than working around OEM limits. A taller airbox lid makes room for a larger flow collector and higher-capacity cone filters, while the carbon turbo inlets gain up to 43% more cross-sectional area. Dimpled internal surfaces cut boundary-layer friction, reducing pressure loss so the turbos spool faster and run lower wastegate duty cycles.

What is it made of, and how is it installed?

Each component is made from 100% prepreg carbon fiber with no fiberglass, giving strong, precise parts with ultra-smooth internal surfaces. The system uses the factory mounting points, but professional installation is recommended given the engine bay complexity. It runs two Eventuri Type L2 cone filters (part EVE-1046-FTR) when replacements are needed.

Can I return it, and is it covered by a warranty?

No, this item is not eligible for return, so verify fitment and your intake configuration before buying. It is covered by warranty, and damage-in-transit support is fully provided, so a system that arrives damaged will be handled. An emissions compliance notice applies, which is worth reviewing for your region.

Description

Eventuri Carbon Intake System for 9YX Porsche Cayenne Turbo / Audi RSQ8 / Bentley Bentayga / Lamborghini Urus

Eventuri’s 4.0TFSI V8 EA825 intake has undergone a complete redesign, optimizing the entire air inlet track to enhance the performance of the twin turbos. Each component was carefully developed to maximize airflow without creating counter-drag effects, resulting in exceptional performance improvements. The airbox lid features a raised central section, allowing for larger components like the flow collector and bigger filters, eliminating obstructions that typically restrict systems using stock lids. With a 43% increase in cross-sectional area compared to the original design, the turbo intakes now include dimpled inner surfaces, reducing friction along the boundary layers and creating an “air cushioning” effect. This design minimizes pressure loss, allowing for higher airflow volumes before the wastegate duty cycle engages, ultimately delivering greater overall performance.

Enlarged Airbox Lid

The initial challenge in significantly increasing the intake volume was the airbox lid. The factory-installed version has a limited opening for the flow collector and restricted access to the filter elements. To overcome this, engineers designed an elevated section at the center of the cover, providing additional space for a larger system collector and substantial filters made from prepreg carbon. These filters are precisely fitted to match the original design while maintaining the factory mounting points for seamless installation.

Carbon Flow Collector & Filters

The flow collector, which directs airflow from the filters to the turbo inlets, was initially limited by its factory design. After addressing this restriction, the revised version showed a significant increase in internal volume. This improvement allowed for the use of higher-capacity cone filters, offering greater airflow and a larger surface area for improved air particle filtration.

Turbo Inlets

The most limiting component of the stock system is the turbo inlets. The OEM inlets not only have reduced internal volume, but also feature two flexible sections, with one located right before the turbine. This section is prone to disruption when exposed to pressure differentials during engine acceleration, causing turbulence. Although flow guides are installed at the outlet to mitigate this, they do not fully eliminate turbulence and present additional obstacles for air passage. To address this, Eventuri has eliminated one of the flexible sections, increasing the inlets’ capacity and reducing airflow resistance, which helps the turbos spool more quickly and efficiently.
Eventuri could have finalized the designs at an earlier stage but chose to push beyond conventional boundaries by incorporating an innovative dimpled formation within the internal structures. The theory behind this approach suggests that small indentations can enhance fluid flow by reducing frictional losses along the tube, improving overall efficiency.
Extensive research and development was conducted to simulate various shapes and sizes before arriving at an optimized design that significantly improves airflow through the intakes. This sophisticated design was made possible through advanced manufacturing techniques, which offer the precision needed to achieve such results—something traditional methods would have lacked. The introduction of dimples creates an “air cushion” effect, reducing surface friction and allowing the main airflow to move more easily into the turbochargers. This approach results in more uniform velocity profiles within confined spaces while increasing overall airflow velocity, enhancing the system’s performance based on the findings of the study.
- Flow studies on increasing the efficiency of the inlet manifold
- Hydrodynamics of laminar flow through dimpled pipes
- The complete system comes together to provide an intake which improves on the stock airbox in performance, aesthetics and sound

Dyno Testing

An independent dyno test conducted by Eurocharged Canada compared the stock airbox to the Eventuri intake and showed consistent power increases across a broad RPM range. These improvements are attributed to lower wastegate duty cycles and earlier peak boost, resulting from the system’s greater efficiency. On the track, the performance gains were equally evident, with enhanced part-throttle response and stronger full-throttle acceleration sustained up to redline in both scenarios.

About Eventuri

Eventuri was founded by a team of engineers and enthusiasts with a background in Aeronautics and tuning – all sharing a passion for cars and performance. After owning various intakes over many years for their own cars and being disappointed with the gains which seldom lived up to their claims – they decided to take things into our own hands and rewrite the book. To set a new benchmark in intake design and technology, above all – to engineer systems which provide real gains and then to publish genuine figures. Their systems are extensively developed using cutting edge design, testing and prototyping methods. With a focus on performance, each design undergoes CFD analysis and is then validated at the prototype stage through volumetric airflow, intake temperature and extensive dynamometer testing. They strive to publish all the development information to illustrate the depths they go to in bringing an intake from concept to reality. Only the best materials are selected for each component – even down to the choice of fasteners and fixings in order to ensure that the quality of the end product is second to none. After many years of disappointment with the usual aftermarket intakes, they are proud to be raising the bar and creating intake systems which are setting a new standard and genuinely improve the performance of your vehicle.

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.
