Does the Eventuri Carbon Intake System fit both the G90 M5 Sedan and G99 M5 Touring?

Yes. The Eventuri Carbon Intake System is engineered for the 4.4L twin-turbo S68 V8 in the G90 M5 Sedan and G99 M5 Touring, 2025-present. Both body styles share the same intake architecture, so the system installs on either. Fitment is direct, with no cutting or permanent modification to the vehicle required.

How does the Eventuri intake actually make more power?

Eventuri's patented Venturi filter housings maintain smooth, laminar airflow to the turbo inlets, while a fully sealed design blocks hot engine bay air. Dual carbon feed ducts, one from the OEM source and a secondary duct near the bonnet shuts, supply cooler, denser air. The enlarged internal tube volume, a 31% increase in cross-sectional area over stock, lets the turbos reach boost sooner with lower wastegate duty cycles.

How much horsepower does the Eventuri Carbon Intake System add?

Independent dyno testing by MSL Performance recorded consistent gains of 14whp and 11wtq across the RPM range, compared directly against the stock airbox in repeated back-to-back runs. The gains come from the turbos reaching peak boost sooner with reduced wastegate duty cycles. No tune is required; the system is a direct bolt-on that delivers these results on an otherwise stock vehicle.

What is the intake made from, and what finishes are available?

Each system is constructed from premium prepreg carbon fiber with CNC-machined hardware, stainless steel mounting brackets, aluminum inlet cowls, and OEM-spec silicone couplers and clamps. It uses bespoke Generation 2 high-flow filters. Two finishes are offered, gloss carbon and matte carbon. Replacement filters are available separately as part number EVE-661-G2-FTR (Type B), with two required per system.

Are turbo inlets included, and what is the return and warranty policy?

No. Some product images show optional turbo inlets, which are a separate Eventuri product and are not included with the intake system. The intake is designed and hand-assembled in the UK, and Eventuri provides full warranty coverage along with damage-in-transit support. Note that this item is not eligible for return, so confirm your finish choice before ordering.

Description

Eventuri Carbon Intake System for G90 & G99 BMW M5

Eventuri developed the G9x M5 intake system to deliver a highly efficient airflow route to the turbochargers while minimizing heat soak for optimal performance. The system features a fully sealed design to block heated engine bay air, while incorporating a dual air feed setup to reduce pressure drop. Air is channeled from the OEM ducts as well as additional inlets near the bonnet shuts, which access a consistently cool zone within the engine bay. These secondary openings not only supply cooler air but also enhance turbo spool audibility within the cabin for a more immersive driving experience. Central to the system are Eventuri’s patented Venturi filter housings, engineered to maintain laminar airflow and reduce turbulence as air approaches the turbo inlets. This design enables lower wastegate duty cycles, contributing to improved throttle response, enhanced acceleration, and a more direct connection to the road.

The Eventuri Difference

The G9X M5 intake system from Eventuri features patented carbon fiber housings combined with Generation 2 bespoke filters, delivering an aerodynamically optimized airflow path from the filters to the turbochargers. Unlike typical cone filters with heat shields, this design utilizes the Venturi effect to maintain laminar flow conditions and reduce drag on the turbos.

Intake Housing Assembly

Eventuri’s filter housings consist of Generation 2 custom filters, aluminum inlet cowls, carbon fiber pods, and integrated tubes. The carbon pods enclose the reverse-mounted filters and sculpt the airflow smoothly toward the turbo inlet tubes. A critical design element is the elimination of the convoluted rubber hose typically found between the airbox and the turbo inlets. Instead, the integrated housings and tubes extend directly to the stock turbo pipes, allowing the entire system to move as one unit with the engine under the strut braces. This approach removes the need for flexible connections, reducing turbulence and resistance, and enabling the turbos to operate more efficiently.

Internal Volume

A further enhancement lies in the increased internal volume of the tubing as it passes through the strut braces on the G90 M5. Eventuri has enlarged the cross-sectional area at this critical juncture compared to the OEM setup, allowing for greater air volume to reach the turbo inlets with reduced restriction. This improvement results in a 31% increase in cross-sectional area over the factory airbox design.
- Internal Cross Sectional Area of Intake Tube at the Strut Brace:
  - Stock Airbox Tube: 6487mm²
  - Eventuri Intake Tube: 8497mm²

Patented Technology

The patented filter housings feature a gradual reduction in cross-sectional area, forming a tapered geometry that accelerates airflow while maintaining laminar conditions—an application of the Venturi effect. Functioning like a large velocity stack, this design promotes even velocity profiles as air exits the housings. Eventuri’s bespoke filters complement this flow behavior, and additional technical details are available on the Technology and Filters pages.

Carbon Fiber Dual-Feed Ducts

To ensure a consistent cold air supply, Eventuri has designed dual-feed carbon ducts. The primary duct connects to the OEM cold air source near the bumper and headlamp, while the secondary feed, positioned near the bonnet shuts, accesses a cooler zone in the engine bay. This dual-feed configuration minimizes pressure drop and maximizes airflow efficiency, while also enhancing turbo acoustics inside the cabin. Crafted from high-quality prepreg carbon fiber, the ducts complete the system with both function and aesthetics in mind.

Dyno Testing

Eventuri’s intake system has undergone independent dyno testing by MSL Performance, directly compared to the stock airbox in repeated runs. Results demonstrated consistent performance gains across the RPM range, credited to the turbos reaching peak boost sooner and with reduced wastegate duty cycles—despite higher dyno cell temperatures during the Eventuri tests. On the road, this translates to sharper throttle response and stronger acceleration all the way to redline.

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.
