Eventuri BMW G2X M340i / M440i B58 Gen 3 Black Carbon Intake System - 2025+

OVERVIEW

The Eventuri Black Carbon Intake System for the BMW G2X B58N2 (Gen 3) is developed specifically for the 2025+ M340i and M440i platform, building on Eventuri's acclaimed G20 B58 architecture with updated tooling for the revised Gen 3 engine bay and turbo elbow. A fully sealed prepreg carbon airbox isolates the filter from radiant engine heat while dual cold-air feeds supply cooler, denser air. The carbon fiber inlet tube opens at 111mm (4.4") internal diameter and tapers smoothly into the OEM turbo elbow, replacing the restrictive factory tract with an uninterrupted path to the turbocharger. Built from 100% prepreg carbon fiber with no fibreglass for a smooth internal surface. Designed and hand-assembled in the UK.
