Performance Increase with OEM ECU tune: 20-22hp, 8-13ft-lb

Presenting a World first – the Eventuri Hybrid Airbox System, a breakthrough intake solution for the iconic BMW E46 M3. 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, E46 M3 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.

Eventuri are providing all the parts required to install the airbox and get the car on the road. Usually with CSL style airboxes, there are additional parts required such as the ECU tune and breather pipes. Since our airbox uses the OEM MAF Sensor, there is no need for an aftermarket tune and we also provide the breather hoses.

The Eventuri E46 M3 Hybrid Airbox System comes in 2 configurations, with and without the Eventuri intake. We are offering the airbox without the intake to allow existing E46 M3 owners with Eventuri intakes to be able to reuse their filter housing and scoop.

The Full Eventuri E46 M4 Hybrid Airbox System consists of:

• Carbon Fiber Main Airbox
• Carbon Fiber Airbox Snorkel with MAF tube
• Thermoplastic Molded Trumpets with Stainless Steel Reinforcement Rings
