Description EVENTURI EVE-G20B58N2-CF-INT Air Intake System (Carbon) for BMW M340i (G20 / G21) / M440i (G22 / G23 / G26) 2025-

The Eventuri Gen 3 B58 intake system builds on the acclaimed G20 B58 system and is updated specifically for the 2025+ platform. The design focuses on maximising airflow while minimising intake temperatures.

The fully sealed Airbox isolates the intake from Engine bay heat and incorporates a gold-reflective Heat shield to reduce radiant heat transfer. A secondary fresh-air feed from the wheel arch increases airflow into the sealed Airbox.

A smooth Carbon Fiber Intake tube replaces the factory convoluted design and tapers to the OEM Turbo inlet for an uninterrupted Flow path. The custom high-Flow Dry filter provides a larger filtration area than the stock Panel filter and features ISO-tested filtration performance.

• Delivers the B58 turbocharger a cooler, higher-volume, and less restrictive air supply
• Large-volume sealed Airbox with dual cold-air feeds
• Recessed Airbox section accommodates potential Strut braces
• 100% pre-preg Carbon Fiber construction with no fibreglass

Dual-Feed Carbon Fiber Airbox

The pre-preg Carbon Fiber Airbox seals the Cone filter against Engine bay heat while providing dual cold-air feeds. It encapsulates the filter while maintaining a large internal volume. A laser-cut plate with a rubber sealing strip secures to the Airbox and seals around the Intake tube.

An additional Heat shield with gold-reflective backing reduces Heat soak from the exhaust manifold. The secondary scoop extends into the wheel arch to reduce restriction and incorporates an internal splash guard to deflect water away from the filter.

Carbon Fiber Intake Tube

The factory Intake tube has a flexible, convoluted section that can create turbulence. The smooth Carbon Fiber Intake tube provides a larger internal volume and tapers to the stock Turbo inlet to keep airflow as laminar as possible.

Bespoke Cone Filter

The Cone filter uses a double-layered, non-woven mesh material and is ISO tested to provide filtration in line with OEM standards. It is cleanable and stable at high temperatures, with a urethane base material.

An internal Flow-guiding cone helps airflow converge while reducing the possibility of a stagnation point in the centre of the filter. The filter medium has a significantly larger surface area than the stock Panel filter.
