Eventuri Carbon Fibre Intake Kit BMW M135 F70, M235 F74, U1X X1 & X2 M35 Eventuri Carbon Fibre Intake Kit

Each intake system includes:

• Carbon Fibre Venturi Filter Housing with integrated sensor tube

• Bespoke High-Flow Dry Air Filter

• Carbon Fibre Cold Air Inlet Duct

• CNC Machined MAF Boss

• Laser-Cut Stainless Steel Mounting Brackets

Every element works together to create a direct, efficient airflow path from the intake duct to the turbo inlet.

At the core of the system is Eventuri’s Generation 2 carbon fibre filter housing, which integrates the bespoke high-flow filter, aluminium inlet cowl, stainless mounting bracket, and sensor section into a single airflow-optimised unit.

The carbon fibre housing encloses a reverse-mounted cone filter, guiding incoming air smoothly toward the sensor section and turbo inlet. Unlike the factory airbox, which forces air to change direction multiple times, the Eventuri design creates a far more direct flow path.

In the OEM configuration, airflow must:

1. Enter the airbox

2. Turn 90 degrees through the panel filter

3. Turn another 90 degrees toward the intake hose

The Eventuri system eliminates these abrupt direction changes. Air enters the front of the housing and moves directly through the filter and sensor section, resulting in reduced turbulence and improved airflow efficiency.

This smoother airflow path allows the turbocharger to operate with less restriction and reduced drag.

Eventuri’s patented carbon fibre housing gradually reduces its internal cross-section as it tapers toward the outlet tubing. This carefully engineered geometry produces the Venturi effect, accelerating airflow while maintaining laminar flow conditions.

The design functions similarly to a large velocity stack, ensuring air travels smoothly through the housing and exits with a consistent velocity profile. Combined with Eventuri’s bespoke performance filters, this system maximises airflow efficiency while maintaining excellent filtration.

The carbon fibre inlet duct draws cold air from the factory air feed located behind the front bumper, but with a significantly improved flow path compared to the OEM duct.

Using carefully designed organic curvature, the duct smoothly guides air toward the filter housing opening, improving airflow efficiency and reducing turbulence.

The duct seals against the filter housing using expandable rubber edging, allowing for engine movement and vibration while maintaining a secure air seal.

For a clean engine bay appearance, the duct mounts directly to OEM locations using hidden hardware.

The final element of the system is Eventuri’s custom flexible coupler, which connects the filter housing to the turbo inlet tube.

This component allows the intake housing to remain fixed and sealed to the duct, while still accommodating engine movement under load. The result is a stable, sealed intake system that maintains optimal airflow regardless of engine movement.
