Eventuri Black Carbon Fiber Intake System w/ Secondary Duct for B9 Audi RS4 and RS5

The Audi B9 RS4/RS5 Eventuri intake was developed to give less restrictive airflow to the turbo whilst maintaining low inlet temperatures. The RS5/RS4 engine bay becomes heat soaked very quickly so simply having an open cone system would result in better airflow but with higher inlet temperatures. Eventuri therefore completely re-engineered the inlet track from the turbo inlet pipe to the front grill with a highly efficient sealed system. The restrictive stock airbox and flexible plastic inlet pipe have been replaced with a Venturi filter housing and a duct system with smooth transitions. Furthermore, by removing the convoluted stock inlet pipe and replacing it with our one-piece Venturi housing and solid tube, the airflow is much smoother as it enters the turbo inlet tube. The resulting performance gains and aesthetics are industry leading for this platform.

The Eventuri B9 RS4/RS5 intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards.

All the components come together in the engine bay to produce a genuine improvement in the driving experience as well as providing an incredible visual display of form and function in complete harmony.

The Eventuri Difference

  • The B9 RS4/RS5 Eventuri system uses their Patent Pending Carbon fiber Housings with their bespoke Gen-2 filter which provide an aerodynamically efficient airflow path from the filter to the inlet tubes. Not just another cone filter with a heat shield but a unique design which invokes the Venturi effect.

Carbon Intake Housing Assembly

  • The filter housing comprises of Eventuri’s bespoke generation 2 filter, the carbon pod and integrated tube. The carbon pod shrouds the reverse mounted filter and smoothly shapes the airflow down to the turbo tube which it matches in diameter to the turbo tube. This is a key feature of the intake design where they removed the requirement for a convoluted rubber hose between the intake and the engine. The filter housing and integrated tube extends all the way to the stock turbo tube and by mounting this to the engine, the entire filter housing moves with the engine. As the engine and filter housing moves under acceleration, it is able to maintain a seal to the duct through the use of an expanding rubber extrusion which is mounted to the face of the duct.
  • This smooth reduction in cross sectional area invokes the Venturi effect where the airflow accelerates whilst maintaining laminar conditions. It can be thought of as a large velocity stack. Their bespoke filters aid the airflow moving through the housings and allow for an even velocity profile as the airflow exits the housings.

Carbon Fiber Intake Duct

  • The duct channels ambient air from the scoop to the filter housing. It also creates a sealed volume of ambient air before the filter so that there is a ready supply which the filter can draw from. The duct has been designed to take maximum advantage of the volume available in the engine bay. In order to ensure a good seal against engine bay heat – the duct also has a flexible rubber edging around the openings which press against the filter housing and OEM front duct creating the desired seal yet allowing the housing to move with the engine. To further enhance the airflow Eventuri added a secondary opening at the rear of the duct in the cold region of the engine bay. This geometrically complex piece is a key part of our B9 S4/S5 design.

Carbon Fiber Secondary Duct

  • For the complete carbon fiber setup they also crafted the secondary duct from carbon. This part connects the main carbon duct to the air entry region on the slam panel. It eliminates the holes on the OEM part and matches the rest of the system for a more finished aesthetic.

Carbon Fiber Air Scoop

  • The final carbon components in this system is the front scoop – essential to direct ambient air to the duct and then to the filter.
  • The scoop was designed with a constant bend radius for maximum efficiency in directing the incoming air to the duct opening. It allows the inlet air temperatures to be as low as possible and increase the rate of drop in IATs after the system is heat soaked during a standstill.

Custom Bracket Work

  • To ensure a perfect fit they spend a lot of development time on the mounting hardware. Like all of their intakes, the brackets are specifically designed for the application and for the B9 S4/S5 system, the brackets are laser cut from stainless steel and then powder coated for durability. The CNC machined mounts are then secured to the brackets and push into the stock rubber mounts which the stock airbox uses to secure to. This ensures the intake fits just like the OEM system.

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.

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.
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.
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.
