Turbo inlet suitable for BMW 4 Series (G2X) M440D B57R

Turbo Inlet suitable for BMW G22 G23 G26 M440d B57

Maximum performance for your BMW G2x M440d: The bionically optimized turbo inlet. Unlock the full performance reserves of your M440d engine with our latest bionically developed turbo inlet – specially designed for the BMW G2x series. Based on computer-aided flow simulations, this component reduces pressure resistance by up to 35% compared to the series – for highly efficient air supply and increased system performance.

Thanks to the bionic geometry, which is based on natural flow patterns, the intake air is guided in a targeted laminar flow, and turbulence is consistently minimized – this means: optimized response behavior, accelerated boost pressure build-up, and maximum efficiency. Especially in the low rev range, the improved airflow ensures that torque and power are available earlier and more sustainably – across the entire rev range for international test applications.

Your technical advantages at a glance:

• Measurably optimized response behavior through minimized pressure loss

• Accelerated spool behavior of the turbocharger in competition

• More power and torque, especially in lower load ranges

• Increased efficiency through highly efficient combustion cycles

• More direct load response for precise feedback in racing operations

• Technically induced modification of intake acoustics

The turbo inlet is designed as a direct plug-and-play upgrade – it uses all original connection points and requires no adjustments during installation. The component is 3D printed from high-strength polyamide, which is at least equivalent to OEM materials in terms of stability and heat resistance – absolutely robust, temperature-resistant, and precisely fitting.

For performance specialists and international export projects:

Our turbo inlet is the ideal choice for all M440d applications that want to achieve the aerodynamic maximum – without compromising on technical manufacturing quality. Optimize your BMW M440d with professional flow technology for global competitive use.

Note on the resonance body:

In this design, we have deliberately dispensed with the standard resonance chamber to prevent performance-reducing turbulences. These chambers primarily serve noise damping ex-works. We aim for maximum performance from every component and thus achieve an acoustic optimization of the flow paths. Additionally, we supply a stopper that is attached to the standard connecting hose to completely eliminate the original resonance body in the export setup. This straightens the flow guidance and creates a more distinctive sound.

Legal Notice:

Developed for international export and motorsport. No ABE or approval within the scope of the StVZO. Installation may lead to the invalidation of the operating license (§19 StVZO).

Delivery time: 

Our products are usually ready for shipment within 2-3 business days, provided they are in stock. If an item is not available due to supply bottlenecks or unexpectedly high demand, it will be remanufactured for you using a high-quality 3D printing process. In this case, the delivery time will be up to 3 weeks to ensure the highest quality and optimal fit.

Included in delivery:

1x Turbo Inlet

1x Delete plug for resonance chamber
