HF-Series intercooler Audi A4 B9, A5 B9, A6 C8, A7 C8 2.0 TFSI / 3.0 TFSI / 3.0 TDI

HF-Series upgrade intercooler for Audi A4/A5 B9 & A6/A7 C8 2.0 TFSI, 3.0 TFSI & 3.0 TDI

Maximum cooling performance. Minimum pressure loss. Developed for the highest performance.

Performance does not start with the software, but with a consistently low charge air temperature.

The HF-Series upgrade intercooler was developed specifically for the Audi B9 and C8 platforms and combines exceptionally high cooling performance with a flow-optimised internal design. The result is considerably more efficient charge air cooling, less pressure loss and a noticeable reduction in strain on the turbocharger.

Whether it is a standard vehicle or a setup with increased power, this intercooler ensures that your engine can unfold its full potential even under high continuous load.

Developed for maximum flow

The heart of the system is our high-quality Bar’n’Plate (BNP) high-performance core.

Together with the specially developed cast aluminium end tanks and our WAY FIN TECHNOLOGY, the entire air path has been optimised using CAD flow simulations.

This results in:

• even air distribution across the entire cooler surface
• minimal turbulence
• reduced pressure loss
• maximum cooling performance

While many intercoolers rely solely on the largest possible core, with HF-Series every detail has been designed for the optimum compromise between cooling performance and flow velocity.

Larger core. More power reserves.

The almost doubled core volume allows significantly higher heat absorption and ensures consistently low intake air temperatures even during repeated full-load accelerations.

Benefits at a glance

1. Optimised flow

The flow-optimised internal design distributes the charge air evenly. Dead zones and unnecessary turbulence are avoided, so the entire cooler works more efficiently.

3. Lower charge air temperatures

Colder charge air contains more oxygen.

This improves:

• combustion
• the knock limit
• power stability
• the thermal capacity of the engine

Even at high outside temperatures or during several full-throttle accelerations, engine power stays considerably more consistent.

4. Earlier response and more power

The lower pressure loss and the lower charge air temperature together ensure:

• earlier boost build-up
• more direct response
• higher power stability
• optimum conditions for software optimisations

Our test bench measurements impressively show the influence an efficiently working intercooler can have on the overall performance of the vehicle.

Why an upgrade intercooler?

As engine power rises, so does the thermal load on the entire charge air system. Especially with software optimisations the boost pressure increases significantly, so that standard intercoolers reach their limits more quickly.

An efficient upgrade intercooler not only provides additional power reserves, but also protects the turbocharger and engine from unnecessary thermal stress.

The lower the pressure loss and the lower the intake air temperature, the more efficiently the whole system works, for more power, better durability and consistently repeatable performance.
