HF-Series intercooler for Audi A6/A7 C7 (4G)

This upgraded intercooler for the Audi A6/A7 4G is a highlight of the HF-Series range. The high-quality HFT core provides excellent cooling properties, delivering strong performance even in demanding conditions while remaining highly robust. It offers high resistance to heat and warms up less than comparable cores from other manufacturers. The complete system is also designed for optimum flow. This means minimal pressure loss, while the entire charge-air path was developed using CAD flow analyses. The end tanks are made from high-strength cast aluminium and feature WAY FIN TECHNOLOGY.

Technical details

• Core type: HFT
• End tanks: cast aluminium

Road use: A parts certificate is included to facilitate registration of the conversion under §19.3.

Comparison: OEM – HF-Series

• Volume: 5,586 cm³ – 14,520 cm³

Product benefits

1. Improved flow and even pressure distribution for maximum efficiency: With WAY FIN TECHNOLOGY, a guide fin in the end tank provides even better flow and a more uniform pressure distribution throughout the core, achieving maximum efficiency.
2. Reduced pressure loss: To achieve the programmed boost pressure, the turbocharger must run at a higher speed when pressure loss is greater. This creates a higher thermal load on the turbocharger and increases wear.
3. Cooler charge air.
4. Earlier response and improved performance.

What exactly does an upgraded intercooler provide?

To express the exact power increase provided by an intercooler in figures, many unknown factors must be considered, such as factory power variation, further hardware modifications and the software used during measurement. This differs from vehicle to vehicle. As a rule of thumb for tuned engines, an increase of up to 5%–10% can be expected.

Just as important is the fact that, whether the engine has already been optimised or remains standard in terms of software, you can prevent a loss of performance at high outside temperatures or the activation of the thermal protection stored in many engine control units. This allows you to rely on the engine’s full performance at all times.

Recommendation

We recommend using HF-Series intercoolers together with hardware and software optimisation. Reducing back pressure, which relieves the turbocharger, and cooling the charge air, which increases the oxygen content in the combustion chamber and reduces thermal load, delivers performance tuning that efficiently uses the potential of every turbocharged engine.

When carrying out hardware or software tuning, the factor of boost-pressure loss must not be overlooked. Increasing vehicle performance through chip tuning also increases boost pressure in 99% of cases. With the standard intercooler, boost-pressure loss rises exponentially. The turbocharger must therefore work even harder, increasing its thermal load and reducing its service life; high engine speeds also cause faster wear.

HF-Series intercoolers provide the ideal balance between cooling performance and boost-pressure loss.

Suitable for: Audi A6 VII (4G/C7), Audi A7 I (4G).
