Eventuri Black Carbon Intake - BMW G2X M40i B58N2 Gen 3 (2025+ 48V)

This is Eventuri's updated B58 intake for the 2025+ M340i, M440i and M240i with the 48V mild-hybrid engine. Like their earlier G20 system, it's built around two goals for a turbo engine: more airflow and lower intake temperatures. A sealed carbon airbox keeps engine-bay heat away from the filter while still giving the turbo a steady supply of outside air.

What you get

• Sealed carbon fiber airbox sized to the G2X engine bay for more internal volume, while keeping factory integration.
• Dual cold-air feeds: the factory front intake plus an extra feed from the wheel-arch area.
• Smooth carbon intake tube in place of the ribbed factory tube, 111 mm inside diameter tapering into the OEM turbo elbow.
• Recess for a strut brace built into the airbox.

Good to know

• Fits only 2025+ cars with the 48V mild-hybrid B58TU. Check your car's production date and engine before ordering.
