The F8X M3/M4 intake system is one of Eventuri's most ambitious intake systems to date. Now in the updated V2 design, it features sealed filter housings to maintain a more steady IAT, even while stationary. The new ducts which seal the housings, coupled with the carbon scoops ensures unrestricted airflow whilst maintaining low IATs through cold air saturation. Every detail was taken into account to ensure that a flagship intake to set a new benchmark for this platform was created. From the scoops to the ducts to the intake tubes – a “complete solution” was developed to ensure a smooth inlet track with cold air saturation. With a carbon weave to match the OEM M Performance carbon – this truly is a new benchmark.

Below is a dyno graph showing the comparison between the Eventuri and the stock airboxes on a standard M4. As you can see, power and torque are increased through a large portion of the rpm range not just at the peak. This translates on the road to increased part throttle and full throttle response with the car pulling much more eagerly to the redline. The testing was done on the same day back-to-back and temperatures were monitored to ensure consistency. Since dyno results vary between consecutive runs, this graph shows the highest power figure achieved with the stock setup vs the highest figure with the Eventuri.

Since the F8x M3/M4 is sensitive to heat soak, dyno figures can vary between runs - we could have shown the highest figure achieved with the Eventuri VS the lowest achieved with the stock setup, however this would not be a fair comparison. Just to illustrate the variation, here is the graph showing highest Eventuri VS lowest stock which was recorded on the day showing a gain of over 31hp!

The filter housings comprise of the high flow filters, aluminium cowls, V-Band clamp, laser cut brackets and the Patented carbon pods themselves. The carbon pods shroud the reverse mounted filter and smoothly shape the airflow down to the intake tubes. This geometry invokes the Venturi effect where the airflow accelerates whilst maintaining laminar conditions. The bespoke filters aid the airflow moving through the housings and allow for an even velocity profile as the airflow exits the housings.

The filter housings are positioned with the openings nestled inside the intake ducts. These ducts have been designed to fit over the stock cold air ducts and direct ambient air into the filters. This ensures that the heated engine bay air is effectively displaced from around the filters whilst the car is in motion.

The filter housings are positioned with the openings sealed against the carbon ducts. These ducts have been designed to fit over the stock cold air ducting channels and direct ambient air into the filters. These ducts seal the openings of the filter housings and prevent heated air from entering the filters.

The intake tubes are again crafted from 100% prepreg carbon fibre. Each tube has an integrated MAF sensor mount which is CNC machined from aluminium. The shorter left side tube smoothly transitions from the carbon housing down to the turbo inlet tube. The larger right side intake tube has to clear the fan shroud and strut brace. To do so Eventuri employed the same principle as the stock tube in changing the cross section from a circle at the turbo inlet tube to an oval for clearance over the shroud, then back to a circle at the filter housing end. This ensured these transitions were gradual so as not to disrupt airflow, furthermore we maintained the same cross sectional area in order to keep the velocity through the tube constant.

The final components in this system are the front scoops - essential to direct ambient air to the ducts and then to the filters. The scoops were designed for maximum efficiency in directing the incoming air to the stock duct openings. Many aftermarket scoops have a large flat area almost perpendicular to the oncoming air - not great for channeling it into the ducts as the airflow just "hits" this flat portion and creates turbulence. The Eventuri Scoops have been designed to sit directly behind the front grills to capture as much air as possible and with a continuous curve to the duct opening to ensure this airflow is efficiently channeled.

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.
