The Audi B9 S4/S5 Eventuri intake was developed to give less restrictive airflow to the turbo whilst maintaining low inlet temperatures. The S5/S4 engine bay becomes heat soaked very quickly so simply having an open cone system would result in better airflow but with higher inlet temperatures. We 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 Difference
The B9 S4/S5 Eventuri system uses our Patent Pending Carbon Fiber Housings with 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 affect.
The Eventuri B9 S4/S5 intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. Here are the details for each component and the design ethos behind them:
Each intake system consists of:
Carbon Fiber Venturi housing with integrated tubeHigh Flow Generation 2 FilterCarbon Fiber Intake DuctCarbon Fiber Front ScoopHigh Quality Silicon Couplers and OEM Spec Hose ClampsLaser Cut Stainless Steel Bracket WorkCNC Machined Mounting StubsThe filter housing comprises of our 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 we have 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 - below is a diagram to show the comparison between our patent pending design and a regular intake system. Our bespoke filters aid the airflow moving through the housings and allow for an even velocity profile as the airflow exits the housings.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 we 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.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.To ensure a perfect fit a lot of development time was spent on the mounting hardware. Like all Eventuri 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. 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 intake was tested on the road using a Vbox unit to record the acceleration from 60-130mph (also 100-200Km/h). Testing was carried out on the same stretch of road - again on the same day to keep variables minimum. Results show that with just the intake added, the acceleration times from 60-130mph reduced by almost 0.5 seconds which is a significant improvement at such speeds. This demonstrates that the gains measured on the Dyno are not representative of how the intake performs on the road when it has the correct flow conditions - on the road the intake shows a larger gain by the reduction in acceleration times as compared to the Dyno.
Acceleration results summary:
60-130mph with Stock intake = 14.72 seconds60-130mph with Eventuri intake = 14.24 seconds100-200Km/h with Stock intake = 12.45 seconds100-200Km/h with Eventuri intake = 12.12 secondsThe gains are from a combination of reasons:
1) The sealed system keeps IATs low - especially with the front air scoop which forces air into the system.
2) The Venturi housing provides a smooth transition from the filter to the intake tube with no convoluted rubber section. This helps the turbo to run more efficiently by maintaining laminar flow in the inlet track.
3) The entire system is constructed from pure pre-preg carbon fiber which is great at insulating from heat.

States.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 the company's cars and being disappointed with the gains, Eventuri decided to take things into their own hands and rewrite the book. To set a new benchmark in intake design and technology, above all – to engineer systems that provide real gains and publish genuine figures.
Eventuri 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. Eventuri strives to publish all the development information to illustrate the company's depths into 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 to ensure that the quality of the end product is second to none. After many years of disappointment with the usual aftermarket intakes, Eventuri is raising the bar and creating intake systems that set a new standard and genuinely improve the performance of vehicles.
