The Eventuri intake system built for the G20 B48 engine—fitting models such as the 318i, 320i, 330i, 330e, and corresponding 4 Series variants—is engineered to reduce flow restriction to the turbo while keeping inlet temperatures low. Because the intake sits near the exhaust manifold, heat management is vital to prevent performance loss from dense, heated air. To combat this, the airbox is fully sealed and features a gold reflective heat shield to minimize radiative heat transfer, alongside a secondary feed utilizing a wheel arch opening to compensate for the single factory inlet.
The layout maximizes volume while accommodating potential strut braces, replacing the restrictive factory hose with a smooth carbon tube that starts at an internal diameter of 111 mm before tapering down to the turbo inlet. Additionally, the kit incorporates a custom ISO-tested high-flow dry filter with an increased surface area compared to the stock alternative.
Kit Includes
- Sealed Carbon Fiber Airbox with Gold Reflective Heat Shield
- Smooth Carbon Intake Tube (111 mm starting diameter)
- Custom High-Flow ISO-Tested Dry Filter
- Secondary Air Feed for Wheel Arch Integration
- Installation Hardware and Couplers
Benefits
- Fully sealed airbox design with gold reflective heat shielding protects intake air temperatures (IAT) from exhaust manifold heat soak.
- Features a secondary wheel arch feed to ensure high airflow volume despite a sealed configuration.
- Replaces the convoluted factory hose with a smooth, large-volume carbon tube tapering from 111 mm for enhanced turbo efficiency.
- Utilizes a custom ISO-tested dry filter with a larger surface area than the OEM component.
