The Eventuri Black Carbon Intake System for the BMW G01 X3 M40i and G02 X4 M40i with the B58D engine has been engineered to provide a significantly less restrictive airflow path to the turbocharger while maintaining low inlet air temperatures in a heat-intensive engine bay environment. Due to the intake’s close proximity to the exhaust manifold, the factory system is highly susceptible to heat soak, which negatively impacts performance. Eventuri’s fully sealed carbon fiber airbox prevents the turbo from ingesting heated air and ensures consistent power delivery under load.
To further reduce radiative heat transfer, the airbox incorporates a laser-cut heat shield lined with gold reflective backing. The internal volume of the airbox has been maximized, including a recessed section to integrate seamlessly with the factory strut brace while increasing airflow capacity. This allows the system to maintain a continuous supply of cold air even during extended driving.
The intake tube is constructed from prepreg carbon fiber and features a large 109mm internal diameter which smoothly tapers to match the turbo inlet. By replacing the restrictive and convoluted factory duct with a single, uninterrupted carbon path, turbulence is reduced and airflow velocity is maintained as it enters the turbocharger. The bespoke high-flow dry cone filter provides a larger filtration area than the OEM unit while maintaining ISO-certified filtration performance.
Engineered for OEM-level fitment and supplied with CNC machined mounting and sensor provisions, the Eventuri intake delivers improved throttle response, enhanced turbo efficiency, and a substantial visual upgrade for the B58D-powered X3 and X4 M40i.
