Eventuri Hybrid Airbox – BMW E46 M3

Introducing the world's first Eventuri Hybrid Airbox system for the legendary BMW E46 M3 . This innovative intake manifold solution combines the aggressive, race-inspired sound of the CSL Airbox with the easy Plug & Play installation of a standard intake manifold.

Previously, E46 M3 owners who wanted the CSL sound were more or less forced to drive without a MAF sensor and have expensive software modifications done — often at the cost of reduced drivability.
The Hybrid Airbox solves this: you get the CSL sound and performance without changing the engine program , while maintaining the smoothness and throttle response of the factory program.

Eventuri advantage

The air filter system is based on Eventur's patented Venturi carbon fiber structure , which ensures a highly efficient and streamlined airflow. This is not just a cone filter with a heat shield — the aerodynamics of the structure produce a Venturi effect and laminar flow , which reduces engine back pressure and improves power output.

Dyno-tested performance

The system has been tested by Dream Automotive in the UK. Comparisons were made directly to the standard air intake over several consecutive pulls. The results show a consistent power increase across the rev range , which is reflected in real-world driving as sharper throttle response and stronger pull all the way to redline.

Power increase with OEM program:
+20–22 hp / +11–18 Nm

The Eventuri E46 M3 Hybrid Airbox system is available in two configurations :
✅ Complete set with intake
✅ Just an airbox , suitable for those who already have an Eventuri intake and scoop in their E46 M3

The complete Hybrid Airbox configuration includes:

• Carbon Fiber Main Airbox
• Carbon Fiber Airbox Snorkel with MAF tube
• Thermoplastic Molded Trumpets with Stainless Steel Reinforcement Rings
• Carbon Fiber Filter Housing
• Bespoke Dry High Flow Filter
• Carbon Fiber Cold Air Scoop
• Stainless Steel Brackets and Flanges
• CNC Machined Breather Adapters
• Custom EPDM Flexible Coupler
• Silicon Couplers
• Crankcase Breather Hose
• Additional Vacuum Tubing

Complete package – everything you need included

We supply all the parts needed to install the airbox and get the car started.
Traditional CSL-style airboxes usually require additional purchases, such as ECU program changes and separate breather pipes.

These are not needed in this series.
Since the system uses the car's original MAF sensor, ECU tuning is not necessary , and we also supply the necessary breather hoses.

The only possible add-on (only for SMG cars) is the SMG tank relocation kit.
