Eventuri BMW F4X M135i M235i / F39 X2 35i B48 Black Carbon Intake System

The Eventuri carbon intake system for the BMW F40 M135i, F44 M235i, and F39 X2 M35i B48 platform has been developed through extensive real-world testing and airflow simulation to deliver a measurable improvement in turbo efficiency, throttle response, and intake air temperature stability. By replacing the restrictive factory airbox with Eventuri’s patented carbon fiber Venturi housing and sealed duct system, this intake provides a smooth and aerodynamically optimized airflow path directly to the turbo inlet.

At the core of the system is the Generation 2 bespoke dry filter, housed inside the carbon Venturi assembly with an integrated MAF tube. This configuration maintains laminar airflow and reduces turbulence before the turbo, allowing the turbocharger to operate with a lower wastegate duty cycle while improving response and mid-range performance. The sealed carbon duct ensures that only ambient air is fed into the system, keeping intake temperatures consistent even under demanding driving conditions.

Unlike open cone designs, the Eventuri system is engineered as a complete intake solution. Every component, from the maximized-volume front duct to the aluminum inlet cowls and precision bracketry, works together to reduce restriction and preserve a stable velocity profile through the intake tract.

The result is an intake system which enhances performance, sharpens turbo response, and transforms the engine bay with Eventuri’s signature pre-preg carbon fiber construction.
