Do I need an existing intake for the Eventuri F8X sealed duct kit?

Yes. The Eventuri F8X sealed duct kit is an upgrade for an existing Eventuri V1 intake on the F80 M3, F82 M4, or F83 M4. It converts that V1 system to the sealed V2 specification and is not a complete intake. It will not function on its own or with a factory or non-Eventuri intake.

What does the sealed duct upgrade actually do?

The Eventuri F8X sealed duct kit closes the filter area off from the engine bay and seals against the factory front air feeds. This lets the intake draw cold air from outside the car instead of hot engine bay air, improving intake air temperature stability and delivering more consistent performance under repeated hard acceleration.

Which cars does the Eventuri F8X sealed duct kit fit?

The kit fits the F80 BMW M3, F82 M4 coupe, and F83 M4 convertible, in each case when the car already has an Eventuri V1 intake installed. Unlike some F8X interior and exterior parts, this duct upgrade does cover the F83 convertible, since the intake and duct layout are shared across the three bodies.

Is installation difficult?

Installation is straightforward. The Eventuri F8X sealed duct kit integrates directly with the existing V1 intake components using the supplied fasteners and factory mounting locations. There is no need to replace the original housings or filters, which makes this the most efficient way to bring a V1 system up to V2 sealed specification.

What is the kit made of, and what is included?

The Eventuri F8X sealed duct kit is made from pre-preg carbon fiber with a high-gloss finish, matching the rest of the Eventuri intake. The kit includes the sealed carbon ducts and the required fasteners. It does not include a filter, Venturi housing, or any other intake component, since those carry over from the V1 system.

Is the Eventuri F8X sealed duct kit returnable?

No. The Eventuri F8X sealed duct kit is not eligible for return once opened, so confirm you have a compatible Eventuri V1 F8X intake before ordering. Eventuri provides warranty coverage and damage-in-transit support, and the kit is designed and hand-assembled in the UK.

Description

Eventuri Black Carbon V2 Sealed Duct Upgrade Kit for F80 BMW M3, F82 M4, and F83 M4

The Eventuri F8X sealed duct kit converts an existing V1 Eventuri intake on the F80 BMW M3, F82 M4, and F83 M4 to the fully sealed V2 specification, swapping the open V1 ducting for revised pre-preg carbon fiber ducts that lock the intake to a consistent supply of cold ambient air. The V2 ducts close off the filter area from the engine bay and seal against the factory front air feeds, so the intake pulls cold air from outside the car rather than from the hot engine compartment; the result is steadier intake air temperatures and more stable performance under repeated acceleration, while the smooth airflow of the Eventuri Venturi housing is preserved. The ducts integrate directly with the existing Eventuri V1 components using the supplied fasteners and factory mounting locations, with no need to replace the original housings or filters.

About Eventuri

Eventuri was founded by a team of engineers and enthusiasts with backgrounds in aeronautics and tuning, all sharing a passion for cars and performance. After owning various aftermarket intakes over the years and being disappointed with gains that seldom lived up to their claims, they decided to take things into their own hands and set a new benchmark in intake design and technology. The goal was to engineer systems that provide real, measurable gains and to publish genuine figures to back them up. Their systems are developed using cutting-edge design, testing, and prototyping methods. Each design undergoes CFD analysis and is validated at the prototype stage through volumetric airflow measurement, intake temperature testing, and extensive dynamometer testing. Eventuri publishes all development data to illustrate the full process from concept to finished product. Only the best materials are selected for every component, down to the choice of fasteners, to ensure the quality of the final product is second to none.

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.
