The Eventuri intake system engineered for post-November 2018 models featuring the G20 B58 engine—such as the G20 M340i, G22 M440i, and G42 M240i—focuses on lowering turbo flow restriction while maintaining low inlet temperatures. Because the intake sits adjacent to the exhaust manifold, heat management is prioritized to prevent performance loss caused by heated, less dense air. To counter engine bay heat soak, a fully sealed airbox layout is utilized, featuring a gold reflective heat shield to reduce radiative transfer and an integrated secondary air feed drawing from the wheel arch area.
The airbox is maximized in volume while accommodating potential strut braces, and the factory convoluted hose is replaced with a smooth carbon intake tube that begins at an inner diameter of 111 mm (4.4 inches) before tapering down smoothly to the turbo inlet. Built entirely from 100% prepreg carbon fiber without fiberglass, the system ensures a smooth internal boundary layer for uninterrupted airflow.
