Description
The Eventuri Gen 3 B58N2 Black Carbon Intake System is a high-flow induction upgrade engineered specifically for the latest 2025+ BMW G2X M Performance models equipped with the 48V Mild-Hybrid B58TU2/B58N2 engine.
Building on Eventuri's proven G20 B58 intake architecture, the Gen 3 system was redesigned around two key requirements of turbocharged engines: maximizing airflow and controlling intake temperatures.
The system uses a fully sealed pre-preg carbon fiber airbox to isolate the filter from radiant engine-bay heat while maintaining a consistent supply of ambient air. The airbox is optimized around the available G2X engine-bay space and incorporates a recessed section to accommodate potential strut braces without compromising its high-volume design.
A smooth 111 mm (4.4-inch) internal diameter carbon fiber inlet tube replaces the factory convoluted intake tract. Its gradual taper toward the OEM turbo elbow creates a smoother, more continuous airflow path designed to reduce turbulence and pressure loss.
The Eventuri intake also features a dual-feed cold-air configuration, combining the factory front intake location with an additional air source from the wheel-arch area. This increases the supply of ambient air to the filter while maintaining the thermal benefits of the sealed airbox.
A bespoke high-flow dry cone filter, gold reflective heat shield, CNC-machined sensor and breather adapters, and laser-cut stainless steel mounting hardware complete the system. The result is a fully integrated induction upgrade developed around the latest B58TU2 configuration.

Airflow & Thermal Management
Turbocharged engines benefit from both reduced intake restriction and controlled intake temperatures. The Eventuri Gen 3 B58N2 intake addresses both areas through its sealed airbox, large-diameter inlet, and dual cold-air supply.
The sealed carbon airbox helps prevent the filter from being exposed directly to radiant heat generated inside the engine bay. At the same time, the dual-feed configuration supplies ambient air through both the factory front intake location and an additional wheel-arch source.
The enlarged 111 mm inlet tube replaces the factory convoluted intake path with a smoother internal surface and gradual transition toward the turbocharger. This geometry is designed to improve airflow efficiency by reducing unnecessary turbulence and pressure loss.
Carbon Fiber Airbox & Inlet Design
The Eventuri airbox is manufactured from pre-preg carbon fiber and optimized to maximize internal volume within the available G2X engine-bay space.
A recessed section is incorporated into the airbox to provide clearance for potential strut-brace configurations. The result is a high-volume sealed intake enclosure that maintains factory-style integration while providing an optimized airflow path.
The matching carbon fiber inlet tube features a smooth internal surface and begins with a 111 mm internal diameter before gradually tapering toward the OEM turbo elbow.
Installation
The Eventuri Gen 3 B58N2 intake is designed around the factory engine-bay layout and uses OEM mounting points for precise integration.
The system includes the carbon airbox, inlet tube, filter, heat shield, CNC-machined adapters, stainless mounting brackets, silicone reducer, clamps, and required installation hardware.
No permanent vehicle modification is required for installation. Verify your vehicle's production date and 48V Mild-Hybrid B58TU2/B58N2 configuration before purchasing.
Replacement Filter
The system uses the Eventuri Type L replacement filter as its replacement filter application.
