Eventuri BMW G2X M40i B58N2 Gen3 Black Carbon Intake System - 2025+ 48V Mild Hybrid

The Eventuri Gen 3 B58 intake builds on our acclaimed G20 B58 system, updated specifically for the 2025+ platform. The design focuses on two key factors for turbocharged engines: maximizing airflow while minimizing intake temperatures

This intake is designed for vehicles produced 2025+ and is only compatible with the 48V Mild-Hybrid B58TU models. Please verify your vehicle's production date and engine configuration prior to ordering.

Turbocharged engines are particularly sensitive to both intake restriction and elevated air temperatures. Eventuri addresses these two factors with a fully sealed carbon fiber airbox that helps isolate the filter from radiant engine-bay heat while maintaining a consistent supply of ambient air. The enclosure is designed around the available space in the G2X engine bay to provide increased internal volume without compromising factory integration.

While the airbox is maximized in volume within the available space, it includes a recessed section to accommodate potential strut braces. A smooth carbon fibre intake tube replaces the factory convoluted design, starting at 111 mm (4.4″) internal diameter and smoothly tapering to the OEM turbo elbow for an uninterrupted flow path.

The intake uses a dual-feed cold-air configuration, drawing air from the factory front intake location while incorporating an additional feed from the wheel arch area. This secondary source increases the amount of ambient air available to the filter while retaining the thermal benefits of a sealed intake system.

From the filter, airflow is directed through a smooth pre-preg carbon fiber inlet tube that replaces the more restrictive factory intake tract. The continuous internal surface and gradual geometry are designed to reduce turbulence and pressure loss as air moves toward the turbocharger, supporting improved airflow efficiency and sharper throttle response.

A bespoke high-flow dry cone filter provides increased filtration surface area while maintaining effective particle filtration. A dedicated gold reflective heat shield further helps reduce radiant heat transfer from surrounding engine components, supporting more consistent intake temperatures during higher-load driving.

CNC-machined temperature sensor and breather adapters provide precise integration with factory components, while laser-cut stainless steel mounting brackets, an OEM-specification silicone reducer, and clamps complete the installation. The result is a complete induction system developed specifically around the latest B58TU2 configuration used in applicable BMW G2X and G42 M Performance models.
