BMW B58 Turbo Inlet – High-Flow Intake Upgrade for Maximum Air Supply

Our high-flow turbo inlet for BMW vehicles with the B58 engine has been developed to specifically optimize the airflow between the intake system and the turbocharger. By redesigning the standard geometry, flow-inhibiting areas and unnecessary resonance volumes are eliminated, allowing for significantly freer airflow.

While the original BMW turbo inlet is primarily designed for noise reduction and comfort, our design focuses on the most efficient air supply possible for the turbocharger. The optimized internal contour reduces turbulence and pressure losses in the intake tract, creating the ideal foundation for performance-enhanced B58 engines.

Benefits of the B58 High-Flow Turbo Inlet

• Optimized airflow through flow-efficient geometry
• Reduction of pressure losses in the intake system
• Removal of factory resonance areas
• Improved conditions for hardware and software upgrades
• High-quality manufacturing via PA12 3D printing process
• High temperature resistance and dimensional stability
• Plug-&-play installation at the original mounting points
• Includes sealing solution for the air filter housing resonance chamber

Developed for the BMW B58 Engine

The turbo inlet is manufactured from high-quality PA12 using an industrial 3D printing process. The special honeycomb structure ensures an optimal ratio of stability, weight, and heat resistance. As a result, the component remains dimensionally stable and durable even under high thermal loads.

Additionally, a suitable plug for the resonance chamber of the original air filter box is included. This allows the intake tract to be further simplified and the air path to be optimized.

Simple Plug-&-Play Installation

All connection dimensions correspond to original BMW specifications. The turbo inlet can be installed without any modifications and fits seamlessly into the existing intake system.
