Eventuri carbon intake kit for BMW G80 M3 CS and BMW G82 M4 CSL

Eventuri karbonový kit sání pro BMW M3 G80 / M4 G82

Presenting an intake which truly sets a benchmark for the BMW G8X M3/M4 platform. We have carried out intensive R&D to develop an intake which not only improves on the stock M3/M4 but also is future proof in its capacity to cater for high powered builds well in excess of 1000hp. Our system is a complete redesign from the airboxes to the turbo inlets with the aim of reducing pressure loss while increasing the flow rate and keeping inlet temperatures low. We have maximised the usage of the available space to employ 2 custom made filters with a 40% larger filtration area than stock. These are used in our Patented Venturi housings to smoothly funnel the air to the turbo inlets.

The inlets themselves are up to 160% larger in cross sectional area than stock and are designed with an advanced dimpled inner surface to reduce frictional losses between the flow and the wall boundary. By allowing a “cushion” of air at the wall surface, airflow is able to move through the inlets at higher flow rates with reduced pressure loss. This allows the turbos to draw air with less resistance and therefore reduce the wastegate duty cycle resulting in higher overall performance.

The Eventuri G8X M3/M4 intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. We use 100% pre-preg carbon fiber with no fibreglass which means we can achieve a smooth internal surface to maintain smoother airflow. Here are the details for each component and the design ethos behind them:

Each intake system consists of:

  • 2 x Carbon Fiber Patented Venturi Filter Housings
  • 2 x Bespoke High Flow Dry Cone Filters
  • 2 x Carbon Fiber Inlet Ducts
  • Carbon Fiber Intake Tube
  • 2 Thermoplastic Turbo Inlets
  • Laser Cut Stainless Steel Brackets
  • Custom Flexible Hose
  • CNC Machined Bracket Mounts and Reinforcement Rings



Filter housing assemblies:

The filter housings comprise of our bespoke generation 2 filters, aluminium inlet cowls and stainless steel brackets. The carbon pod shrouds the reverse mounted filter and smoothly shapes the airflow down to the tube section which then connects to the turbo tubes. This changes the flow path from the OEM airbox where airflow enters the front of the airbox, changes direction by 90 degrees to travel through the panel filter and then changes direction again by 90 degrees to move through the tube section. Our system is a lot more direct with airflow entering the front of the filter housing and and moving into the tube section without any abrupt direction changes. The result is a smoother path from the filter to the turbo inlet tube and therefore the turbo is able to function with less drag.

Our patented filter housing has a smooth reduction in cross sectional area as it shrouds the filter and tapers down to the tubing. This geometry 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 patented 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. Further details can be read in the Technology and Filters pages.

Bespoke cone filter:

In order to achieve the highest flow rate possible we designed a new filter element to make as much use of the space available in the engine bay as possible. This new filter has an outside diameter of 192mm or 7.6" and when flow tested with a housing using a 4" opening is able to flow up to 900 CFM at 28" H2O. The filter medium is ISO tested to ensure that filtration is in line with OEM standards and is also dry. The filter is constructed with our signature flow cones to aid in the Venturi housing principle.

Turbo inlets:

The biggest restriction in the stock system are the turbo inlets. The G8X M3/M4 has an inlet for each turbo and we were able to significantly increase the sizes of both of them. By increasing their sizes, the turbos are able to pull in air with less restriction hence allowing for a quicker spool. In the following photos you can see the differences in the sizes. Although the benefit may be small for a stock car, we expect these larger inlets to be more beneficial for higher states of tune where the target boost pressures are increased.

We could have finalised the designs here however, we wanted to push the boundaries further and introduce a novel dimpled pattern to the inside surfaces. In theory, small dimples can increase the flow rate by reducing the frictional pressure losses through a tube.

A lot of R&D went into simulating different sizes and shapes until we settled on an optimised version which demonstrated a higher flow rate through the inlets in comparison with a smooth surface. Applying such an intricate was only possible due to the advanced manufacturing technique we employed to make the inlets, where traditional methods would not have given the accuracy required. The dimples create an "air cushion" affect over the surface of the inlet which then allows the main body of air to "slip" with less friction through the body into the turbo. This results in a more even velocity profile in a dimpled tube with the net affect being a higher velocity for the same boundary conditions. Here are the CFD simulations showing the re-circulations in the dimples and the higher velocity in the dimpled tube.

Carbon ducts:

To ensure that the intake is fully sealed, the filter housings are mated to these carbon ducts which route cold air from the stock entry locations behind the headlamps. Made from prepreg carbon fiber, the ducts ensure that the engine bay heat is blocked from entering the filters. Simply having heat shields would not work as effectively since they cannot be air tight. There are many small details designed into the ducts such as the machined mounts to secure them to the stock airbox locations and the laser cut bracket work.


Carbon main tube:

The filter housing on the right side of the engine is connected to a long tube to route the airflow to the turbo inlet. Our carbon tube replaces the stock version and has a smoother internal profile with a larger volume. At the filter side it starts with an internal diameter of 4" and maintains this size up to the turbo inlet where is smoothly tapers down. The tube features integral brackets which help to secure the tube in a fixed location.

After a few months of rigorous R&D Bilal is finally ready to unveil the finished Eventuri Intake System in Carbon Fiber for the BMW G80 M3 and G82 M4. He runs you through the final design, taking a closer look at all the ways he has pushed the design to leave no stone unturned. This includes a visit to the classroom and explanation of a new technology that Eventuri are using for the first time in an Intake, an industry first. Finally we get to see the performance data from the Intake System itself, BMW gave Bilal a challenge here by designing a very functional system, but through his experience managed to improve upon it even further.
