RevDop Turbo Inlet B47 – Bionically optimized for BMW 3 Series G-Series

The REVDOP Turbo Inlet B47 for the BMW 3 Series G-Class (G20/G21) is the perfect solution for anyone wanting to extract more power, faster turbocharger response, and maximum efficiency from their B47 engine. Developed using state-of-the-art flow simulation and inspired by bionic principles – learning from natural, efficient structures – our turbo inlet optimizes airflow precisely where the standard path of least resistance wastes too much potential.

The original inlet suffers from significant pressure losses due to resonance chambers, abrupt changes in cross-section, and non-laminar flow. The RevDop Turbo Inlet addresses this issue: By deliberately removing the resonance chambers , using a bionically shaped internal geometry , and increasing the volume cross-section , airflow is optimized and turbulence is minimized. The result is clearly measurable: up to 20% less pressure loss and up to 25% more air volume compared to the stock inlet – a foundation for noticeably improved performance and more efficient combustion.

Why bionic flow optimization makes the difference

Bionics utilizes natural principles to efficiently solve technical problems. In nature, flow paths usually follow the path of least resistance, such as watercourses or air currents – a form of evolution for the optimal use of available energy. Applied to the Turbo Inlet, this means that instead of using a rigid, technical shape, the internal geometry of the RevDop Inlet is based on organic flow patterns, which reduce turbulence and improve airflow.

This allows the intake air to reach the turbocharger more evenly and quickly, which is already noticeable in the standard configuration and becomes even more apparent with tuning setups such as Stage 1 or Stage 2.

Plug & Play – Easy installation and perfect fit

The installation of the B47 Turbo Inlet is incredibly simple and completely plug & play : no modifications to the engine, hoses or software are required , which not only simplifies the installation but also underlines the reliability and everyday usability of the upgrade.

Delivery time:

The turbo inlet is manufactured for you using a special 3D printing process after you place your order. To ensure the highest quality and a perfect fit, we strive for high-resolution printing. The delivery time is therefore currently up to 3 weeks.

Included in the delivery:

1x Turbo inlet

This item is suitable for:

BMW G2x series B47 engine 320d, 318d (other B47 engines must be checked separately, they still need to be test-installed)
