Presenting a World first – the Eventuri Hybrid Airbox System, a breakthrough intake solution for the iconic BMW S54 Z3M. 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, Z3M 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.
DYNO TESTING
This intake has been independently dyno tested on an E46 M3 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.
The Eventuri S54 Z3M Hybrid Airbox 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:

MAIN AIRBOX ASSEMBLY
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.
