HF-Series intercooler for Audi A4/A5 B9 2.0 TFSI and S4/S5 3.0 TFSI

This upgraded intercooler for the Audi A4/A5 and S4/S5 B9 is a highlight of the HF-Series range. The high-quality Bar’n’Plate core provides excellent cooling performance, even under unfavourable conditions, while remaining highly robust. It offers high resistance and heats up less than comparable cores from other manufacturers. The entire system is also designed for optimum flow. This means minimal pressure loss, while the complete charge-air path was developed using CAD flow analyses. The end tanks are made from high-strength cast aluminium and equipped with our WAY FIN TECHNOLOGY.

Technical details:

• Core type: BNP
• End tanks: cast aluminium

Comparison:

• Standard: 540mmx445mmx65mm
• HF-Series: 720mmx145mmx80mm
• Core volume: standard 8.35 cm³, HF-Series 15.62 cm³

Benefits of this product:

1. Improved flow and even pressure distribution for maximum efficiency:
2. Lower pressure loss: To achieve the programmed boost pressure, the turbocharger must run at a higher speed when pressure loss is greater. This increases the turbocharger’s thermal load and wear.
3. Cooler charge air:
4. Earlier response and improved performance:

What exactly does an upgraded intercooler provide?

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

At least equally important is that, whether the engine has already been optimised or is to remain standard in software terms, you prevent a loss of performance at high outside temperatures or the activation of the thermal protection stored in many control units. This allows you to rely on the engine’s full power.

Recommendation

Use our HF-Series intercoolers in combination with hardware and software optimisation. Reducing back pressure, thereby relieving the turbocharger, and cooling the charge air, thereby increasing the oxygen content in the combustion chamber and reducing thermal load, creates an effective performance upgrade that efficiently uses the potential of every turbocharged engine.

When tuning your vehicle in hardware or software terms, the factor of »boost pressure loss« must not be overlooked. If you increase your vehicle’s performance through chip tuning, boost pressure will also increase in 99% of cases. Using the standard intercooler causes boost pressure loss to rise exponentially. This means the turbocharger has to work even harder, increasing its thermal load and reducing its service life; high rotational speeds also accelerate wear.

Our HF-Series intercoolers create the perfect balance between cooling performance and boost pressure loss.

Road use: The product includes a parts certificate for registration or approval under §19.3.
