Eventuri Black Carbon Intake System for G0X BMW X3 and X4 M40i

Eventuri develops the X3 M40i intake to deliver a less restrictive airflow path while maintaining low inlet temperatures. Given the intake’s proximity to the exhaust manifold on the M40i, under-hood heat can rise quickly and elevate IATs; Eventuri counters this with a fully sealed air box that prevents the turbo from ingesting hot engine-bay air. The air box integrates a gold-lined heat shield to limit radiative heat transfer from the manifold and is maximized in volume with a dedicated recess for the strut brace to increase available airflow. Replacing the factory convoluted tube, a pre-preg carbon intake tube with a 109mm internal diameter tapers smoothly to the turbo inlet for an uninterrupted flow path. A custom high-flow dry filter, validated to ISO filtration standards and offering a larger surface area than stock, completes the system for consistent, low-restriction performance.

Carbon Fiber Airbox

Eventuri constructs the air box from pre-preg carbon fiber to fully shield the filter from engine-bay heat. Positioned beside the exhaust manifold, the air box encapsulates the filter while maintaining a generous internal volume. A laser-cut plate with an integrated rubber sealing strip secures to the air box, allowing the intake tube to pass through while preventing heated air from entering. To further mitigate heat soak, an additional heat shield on the manifold side finished with a gold reflective layer reduces radiant heat transfer.

Carbon Inlet Tube

Eventuri replaces the OEM flexible, convoluted inlet with a smooth, larger-volume carbon tube to eliminate turbulence and stabilize flow. Maximized for capacity, the design increases internal diameter from the factory 80.8mm to 109mm an 82% gain in cross-sectional area then tapers seamlessly to the stock turbo inlet to preserve laminar conditions. Precision CNC-machined provisions for the temperature sensor and breather adapter ensure an exact, OE-quality integration.

Bespoke Cone Filter

Eventuri’s cone filter uses a double-layer, non-woven mesh that is ISO-tested to meet OEM-level filtration. Built on a heat-stable urethane base, the cleanable element integrates an internal flow-guiding cone to converge airflow and avoid central stagnation, while its increased media surface area surpasses the stock panel filter for sustained, efficient breathing.

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.

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.
