The Eventuri Z4M Intake System - Details:
The Design Brief:
- Increased HP and Torque under full throttle
- Improved driving under partial load and throttle response
- Uses high quality engineered parts
- Is a fully engineered complete intake solution
- Adds to the driving experience with a purposeful induction note and no loss of low rpm smoothness
- Affordable
- Standalone upgrade which requires no tuning or MAF removal
The development of the S54 intake system started in early 2014 with preliminary tests carried out on 4 individual cars. Some cars were stock, others had performance parts fitted.
Our aim was to bring a high quality kit to the market with the REAL results. After many months of development we are happy to announce the Eventuri Intake System for the S54 engine and now specifically for the Z4M, which meets our design brief and provides genuine improvement not just in peak power but in throttle response and smoothness.
The Eventuri Difference
The Eventuri system uses our unique Carbon fibre Housing which provides an aerodynamically efficient airflow path from the filter to the MAF tube. Most intake systems use a cone filter with a type of shroud as a heat shield. In this configuration the filter is doing the job of shaping the airflow to the MAF tube and this is where restrictions arise as the airlfow has to negotiate a sharp reduction in diameter from the base of the filter to the MAF tube. In the Eventuri system, the filter is inverted and decoupled from the MAF tube - the carbon housing itself dictates the shape of the airflow by smoothly reducing in diameter from the filter to the MAF tube. Here - the entire carbon fibre housing is a Venturi where the airflow increases in velocity as the cross sectional area smoothly reduces. As this is essentially a large funnel - the airflow remains laminar and therefore minimises the drag of the system.
The result is an immediate improvement in throttle response, smoother power delivery and more power across the rpm range - not just at the peak. Furthermore - this intake releases the engine note for a more pronounced induction roar under full throttle.
Components
Each component is engineered for a purpose and to a very high standard. Each Z4M System consists of:
- 100% Prepreg Carbon Fibre Intake Housing
- Aluminium inlet cowling
- High Flow Filter
- CNC Machined MAF tube
- Laser Cut and Powder Coated Aluminium Scoop
- Aluminum heat shield with neoprene lining
- High quality Silicon coupler with BMW spec hose clamps
Carbon Housing Assembly
Made from 100% prepreg carbon fibre of the highest quality, the workmanship on the housing is second to none. This is mated to an anodised aluminum inlet cowl to ensure a smooth inlet flow path. Finally the assembly is then mated to an aluminium heat shield which is insulated with neoprene and effectively shrouds the intake from engine bay heat and encapsulates the ambient air being diverted from the scoop. Finally we have also incorporated a clip to secure the coolant hose.
MAF tube:
The MAF tube is CNC machined from aluminum and then anodised. The MAF boss itself is machined from an engineering plastic to minimise the heat soak into the sensor through conduction. We have incorporated a machined recess on one side to allow the OEM rubber gasket from the stock airbox to be used for a perfect seal into the stock elbow.
Cold Air Scoop
Laser Cut from Aluminium and then powder coated - the Z4M air scoop directs ambient air directly into the filter opening and effectively keeps IAT's down. Unlike other aftermarket scoops - there is no drilling required to install. This scoop simply clicks into place using the factory hole locations and the supplied push rivets.
Dyno Results
Below is a dyno graph showing the comparison between the Eventuri and the stock airbox on a completely standard car with standard map. As you can see, power and torque are increased throughout the rev range and the power curve is even smoother than factory. This translates on the road to increased part throttle and full throttle response with the car pulling much more eagerly to the redline.
IAT Testing Stock vs Eventuri
The below graph shows Inlet Air Temperature logged through the OBDII whilst dyno testing the stock airbox vs Eventuri back to back. As you can see the Eventuri Intake keeps the temperature consistently lower than the stock airbox. This is a key element along with the increased airflow to ensuring consistent power gains.
Some of our customers quotes:
"It feels like it's in M Sport mode without the sport button being pressed!"
"Smooth and Buttery. That's how it feels."
"The Eventuri intake just sounds in-tune.... you can almost hear the harmonics of the air entering the plenum / engine"
"So the most noticeable thing abut this kit is how much difference it makes to throttle response. It has improved so much it is hard NOT to notice.
"This is how it should have felt from factory!"
