Eventuri Black Carbon Fiber Intake System for FK8 Honda Civic Type R

Eventuri Black Carbon Fiber Intake System for FK8 Honda Civic Type R

The Honda FK8 Type R intake is the result of extensive design iteration through dyno testing and flow analysis. It was developed to achieve two objectives – 1) Maintain low inlet temperatures. 2) De-restrict the turbo inlet path. The first objective was met by enclosing the filter inside a carbon airbox and using the stock seal against the hood to block out the heat soak from the engine. Since the intake sits directly behind the radiator it is crucial that the filter is not exposed which would result in a loss of power through high IAT. The second objective was met by removing the flexible tubing and optimizing the inlet path with a Venturi stack connected directly to the filter. Furthermore, Eventuri added a second inlet to the airbox with a scoop pulling in air from the inner wing area. This almost doubles the total cross sectional area through which the turbo can draw from as compared with the single entry on the stock system. The carbon airbox enclosure has been designed to maximize the use of the available volume and block all sources of heat. The resulting performance gains and aesthetics are industry leading for the FK8 Type R.

The Eventuri FK8 Type R intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standard.

Carbon Airbox Enclosure

The enclosure has been designed to make the most effective use of the volume given when removing the OEM airbox. It shields the filter from the multiple sources of heat in the engine bay. The most direct source is the radiator and fan which pushes a stream of hot air directly into the intake area. The other significant heat sources are the turbo and downpipe which sit next to the intake area and once the engine is up to operating temperatures, the engine bay becomes quickly heat soaked. All these heat sources require a complete airbox system as shielding – a simple cone and heat shield just cannot do the same job. During development we tested open filters with heat shielding and the inlet temperatures increased significantly causing a loss of power. The airbox prevents these heat sources from adversely affecting the cone filter.

Carbon Venturi Tube

To connect the cone filter to the stock turbo pipe, Eventuri designed a tube with an integrated MAF sensor mount and an innovative Venturi stack matched to the inner diameter of the filter neck. This curvature allows the airflow to remain laminar as it goes through the filter and enters the tubing. This replaces the stock flexible rubber tube which has several deep ridges and creates turbulence in the flow path. To maintain a degree of flexibility – the tube is independent of the airbox enclosure and is able to move within the airbox, which relieves any stresses from the engine movements. The Eventuri tube design results in an aerodynamically efficient flow path from the filter to the turbo allowing the turbo to generate boost more effectively and reduce lag. On the road this is noticeable with the car having a sharper and more eager throttle response as boost is generated quicker.

Flow Simulation

As part of their R&D process they carry out flow simulations through their intake systems to ensure that the initial concepts and calculations are reasonable. The simulation also helps them to further optimize the system for smoother airflow where possible.

The flow simulation through a single tube shows an increase in velocity from the filter to the outlet – which is expected as the cross sectional area reduces. It also shows the smooth transition between the filter and tube with the Venturi stack allowing the airflow to narrow down while remaining laminar in nature.

Secondary Inlet Scoop

To de-restrict the turbo Eventuri had to increase the area through which it can draw air from. The stock opening behind the bumper simply was not large enough at approximately 35cm^2 so they added a second feed in the form of this scoop which seals against the base of the airbox and opens up in the inner wing area which is away from the heat sources of the engine. This adds an extra 28cm^2 cross sectional area from which the turbo can draw air from and testing showed that this was significant enough to improve the overall engine performance.

Full Silicon Hose

The final component is their new silicon hose which replaces the OEM hose and breather assembly all the way to the alloy turbo tube. The hose removes all the interfaces between the carbon intake and the metal turbo tube. Furthermore Eventuri has incorporated an internal step which mates to the OEM metal tube. This eliminates the exposed edge of the metal tube which is exposed with other aftermarket silicon hoses. This silicon hose is the final part of the intake and allows for smooth airflow from the intake to the turbo tube.

Total Airflow

With all components assembled the intake is able to provide a derestricted source of airflow to the turbo with inlet temperatures kept down to a minimum. Furthermore with the airflow being smooth – the turbo is able to function more efficiently and therefore the engine produces more power.

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.

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.

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.

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 [email protected] with any inquiries.
