Performance Increase with OEM ECU tune (E46 M3 figures): 20-22hp, 8-13ft-lb

Presenting a World first – the Eventuri Hybrid Airbox System, a breakthrough intake solution for the BMW E85 Z4M. This system delivers the aggressive, race-inspired sound of the CSL Airbox with the seamless driveability and plug-and-play simplicity of a traditional intake. Until now, Z4M owners wanting the CSL airbox sound had to compromise on running the engine without the MAF sensor, often leading to expensive ECU conversions or remaps, where throttle response and driveability were negatively affected. Our Hybrid Airbox solves this problem and delivers the sound and power of a CSL airbox without the need for a remap, as well as the driveability and smooth performance delivery of a regular intake.

The Eventuri Difference

The airbox uses our Patented Venturi Carbon Fiber Housing which provides an aerodynamically efficient airflow path. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect and maintains laminar flow conditions to reduce the drag on the engine. You can read more about the housing design and how it works HERE.

DYNO TESTING

(E46 M3 Airbox results shown) This intake has been independently dyno tested by Dream Automotive in the UK. Tests were done back to back against the stock airbox and several runs were taken with each configuration. The dyno results show a consistent gain throughout the RPM range which can be attributed to the smoother pathway through the intake and airbox to the throttle bodies. The performance gain translates on the road to increased part throttle and full throttle response with the car pulling much more eagerly to the redline.

Parts Breakdown

The Main airbox section houses the 6 trumpets as well as the breather system connectors. Made from prepreg carbon fiber, the airbox has been designed to resonate under load and produce the sought after CSL sound. One of the challenges of the construction was to ensure the long-term reliability of the interface between the trumpets and the airbox. This was resolved by using mechanical fasteners and gaskets to ensure an airtight seal which would not be affected by heat cycles and vibrations. A similar method was also used for the breather adapters.

The trumpets have been made with thermoplastic. The manufacturing process ensures accuracy while keeping the inside surfaces smooth for airflow. This was more advantageous over making each one in carbon fiber as we can ensure perfect form for each trumpet with an accuracy not attainable with carbon. We also added CNC machined stainless steel rings to the trumpets to ensure that they do not deform when the silicon couplers are tightened onto them.

The snorkel or lid of the airbox smoothly channels airflow from the intake to the trumpet area. This section also incorporates the MAF tube section where the OEM sensor is secured to a CNC machined MAF boss. The snorkel secures to the main airbox section using custom made screws which cut into plastic securing clips ensuring that they do not come loose under vibration.

The filter housing comprises of our bespoke generation 2 filter, stainless steel bracket and the Patented Venturi carbon fiber housing. The carbon pod shrouds the reverse mounted filter and smoothly shapes the airflow down to the plenum. This is a key feature of the intake design where we have removed the tortuous flow path of the OEM airbox and therefore reduced the pressure loss through the whole system. This also ensures that the airflow is smooth when entering the MAF tube section of the airbox to allow the sensor to operate without errors.

CFD OPTIMISED 

The overall shape of the airbox was optimised over several iterations using CFD simulations to ensure the trumpets had adequate flow without suffering from starvation due to restrictions in geometry or turbulence.
