Falls jemand das noch jemandem hilft, ich habe mal bei einem Hersteller von LLK's nachgefragt, ob man den 320d mit dem LLK vom 330d problemlos ausstatten kann und wie sich das auf den Motor auswirkt.
Hier die offizielle Antwort vom Hersteller:
Thank you for your detailed and well-formulated questions.
You're absolutely right — the NRF 30955 offers approximately 25% more core volume than the NRF 30482 due to the increased depth, which in theory could provide enhanced thermal efficiency.
We have reviewed the technical drawings and product specifications, and I can confirm the following:
- Mounting and Connections: Both intercoolers share the same overall length and height (496 × 133 mm), and based on the available data, the mounting points and inlet/outlet connections (diameter, position, and angle) appear to be identical.
- Inlet/Outlet Diameter: Ø61 mm ±0.3
- Center-to-Center Distance (Inlet to Outlet): 603 mm
- Inlet/Outlet Angle: 41°
- Mounting Brackets – Center-to-Center Distance: 355 mm ±1
- Internal Flow Characteristics: There is no indication that the internal cross-section or airflow path has been altered. The increased performance is primarily due to the deeper core, which adds more external cooling surface and internal air volume.
- Effect on Turbo Response: While the increased core volume may slightly affect airflow characteristics, any potential impact on turbo response or lag is expected to be minimal.
In conclusion, while NRF 30482 remains the officially listed intercooler for your engine variant, NRF 30955 may indeed be a suitable alternative for those seeking improved cooling, provided there is sufficient space in the vehicle to accommodate the deeper core.

Finde ich sehr lobend, dass die auch auf so kleine Anfragen direkt eingehen. Ich werd meinen demnächst auf 330d upgraden.
