The Eventuri intake system engineered for pre-November 2018 models featuring the G20 B58 engine—such as the G20 M340i, G22 M440i, and G42 M240i—is designed to provide the turbo with a less restrictive flow path while maintaining low inlet temperatures. Because the intake is positioned near the exhaust manifold, it rapidly heat soaks the engine bay, which is detrimental to engine performance since the turbo would need to build boost with heated, less dense air. To ensure intake air temperatures (IAT) are kept to a minimum, a fully sealed intake is required, though this normally restricts airflow to a single stock air feed. During development, an additional opening in the wheel arch area was utilized to add a secondary feed to the airbox.

Furthermore, the sealed airbox includes a gold reflective heat shield to minimize radiative heat transfer from the exhaust manifold. To maximize volume, the airbox is made as large as possible with a recess for potential strut braces. The stock convoluted intake tube is replaced with a smooth carbon tube featuring a starting internal diameter of 111 mm (4.4 inches) that smoothly tapers down to match the turbo inlet. Finally, a custom-made high-flow dry filter that is ISO tested for filtration performance and features a larger filtration area than the stock filter is included. The entire system is fabricated from 100% prepreg carbon fiber with no fiberglass, achieving a smooth internal surface to maintain smoother airflow.

Kit Includes

• Carbon Fiber Airbox with Dual Feeds
• Bespoke High Flow Dry Cone Filter
• Carbon Fiber Inlet Tube
• CNC Machined Temperature Sensor Mount
• CNC Machined Breather adapter
• Heat Shield with Gold Reflective Backing

Benefits

• Fully sealed airbox configuration with a gold reflective heat shield protects intake air temperatures from exhaust manifold heat soak.
• Incorporates a secondary wheel arch feed to provide high airflow volume despite the sealed structure.
• Replaces the restrictive factory hose with a smooth-walled, large-capacity carbon tube starting at a 111 mm diameter.
• Constructed from 100% prepreg carbon fiber devoid of fiberglass to achieve an optimized, unobstructed internal pathway.
