Eventuri Carbon Intake Kit for BMW M340i (B58) G20 / G21

About Eventuri!

Compatible with BMW G2X 340i / 440i, the Eventuri B58 intake system delivers less restrictive airflow to the turbo while maintaining low intake temperatures. Positioned near the exhaust manifold, the stock intake experiences high heat, reducing air density and limiting performance. To prevent this, the sealed airbox includes a heat shield with a reflective gold coating and features a secondary air inlet drawing from the wheel arch, in addition to the original intake. The airbox has been maximized with a recess for potential strut bars. The stock convoluted intake tube is replaced by a smooth, larger-volume carbon fiber duct, starting at an internal diameter of 111 mm and gradually tapering to the turbo inlet, ensuring smooth airflow. A specially designed high-flow filter, ISO-tested and with a filtration area larger than the stock part, completes the system for optimal air delivery.

After years of using various intake systems and finding that the advertised gains were rarely achieved, the Eventuri team decided to take matters into their own hands and reinvent the concept. Their goal: to set a new benchmark in intake design and technology, create systems that deliver real gains, and publish authentic figures. Their systems are thoroughly developed using advanced design, testing, and prototyping methods.
