BMW F8X M3/M4 V2
Performance Gain: 15-20hp, 18-23ft-lb
The F8X M3/M4 intake system is one of our 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 our scoops ensures unrestricted airflow whilst maintaining low IATs through cold air saturation. Every detail was taken into account to ensure that we created a flagship intake to set a benchmark for this platform. From the scoops to the ducts to the intake tubes – we developed a “complete solution” 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.
The Eventuri Difference
The F8X M3/M4 Eventuri system uses our Patent Pending Carbon fibre Housing which provides an aerodynamically efficient airflow path from the filter to the MAF tube. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect.
Below is a dyno graph showing the comparison between the Eventuri and the stock airboxes on a standard F80 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 F80 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 Eventuri F8X M3/M4 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:
- 2 Carbon Fiber Venturi housings
- 2 High Flow Gen 2 Filters
- 2 Aluminium Cowls for smooth airflow entry
- Left Side Carbon Tube with integrated MAF sensor mount
- Right Side Carbon Tube with integrated MAF sensor mount
- 2 Carbon Fiber Sealed Intake Ducts
- 2 Carbon Fiber Front Scoops
- Laser Cut Stainless Steel Brackets
- High quality Silicon couplers with BMW specification hose clamps
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.
Having an effective cold air feed to the filters is an essential part of our design. Simply having some heat shields in place is not an effective means of avoiding heated air from entering the filters unless the shields create an air tight envelope around the filters. The scoops and ducts in our system combine to provide the filter openings with ambient air and maintain low intake air temperature. To illustrate the effectiveness of this system, we put together video:
