Turbo Inlet suitable for BMW B47/N47 16d 18d 20D F-Series

BMW N47 Turbo Inlet – Bionically Optimized High-Flow Inlet for 16d, 18d & 20d Models

Our high-flow turbo inlet for BMW N47 diesel engines was developed to specifically optimize the airflow between the intake system and the turbocharger. By using modern CFD flow simulations and a bionically optimized internal geometry, flow-related losses compared to the standard intake system could be significantly reduced.

The optimized airflow ensures a more homogeneous flow to the turbocharger, reduces turbulence in the intake tract, and creates the basis for more efficient airflow. Especially in performance-optimized vehicles and those with increased air demand, the improved flow characteristics can show their advantages.

Additionally, the standard resonance chamber of the air filter box is disabled. For this purpose, we supply a precisely fitting cover plate, which further optimizes the airflow and can additionally reduce pressure loss.

Bionic Flow Optimization

During the development of our turbo inlet, the flow quality within the intake tract was the focus. Using modern CFD simulations, the critical areas of the series component were analyzed and specifically optimized.

The bionically inspired geometry is based on natural flow forms and enables more controlled airflow to the turbocharger. This reduces turbulence and guides the air mass more evenly to the compressor.

Optimized Air Supply for the Turbocharger

Efficient air supply is the basis for powerful boosting. Due to the revised geometry, the airflow is guided to the turbocharger with less loss, and the flow conditions within the intake tract are improved.

Especially in the lower and middle speed range, this can be noticeable through more direct response and faster boost pressure build-up.

Resonance Chamber Delete Included

The scope of delivery includes a suitable cover plate for disabling the standard resonance chamber in the air filter box.

By eliminating this additional resonance volume, the airflow is simplified, and the intake tract is further optimized. At the same time, a more direct intake characteristic is created.

High-Quality Manufacturing from PA12 and PU

The turbo inlet consists of a high-strength PA12 hard component, which is manufactured using industrial 3D printing. The system is complemented by a specially manufactured PU molded hose with a Shore hardness of A65.

This material combination ensures high dimensional stability, temperature resistance, and a long service life even under demanding operating conditions.

Plug-&-Play Installation

All connections and mounting points comply with the OEM specifications of BMW N47 engines. Installation is carried out without any adjustments and can be performed directly at the original connection points.

Scope of Delivery

• 1x Turbo Inlet hard component made of PA12
• 1x Turbo Inlet molded hose made of PU (Shore hardness A65)
• 1x Set of stainless steel clamps
• 1x Resonance chamber delete kit including cover plate

Delivery Time

Our products are usually ready for shipment within 2-3 business days, provided there is stock available.

If an item is unavailable due to high demand or supply bottlenecks, production will be carried out using the high-quality PA12 3D printing process. In this case, the delivery time is up to 3 weeks.
