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

This upgrade intercooler for Audi A4/A5 and S4/S5 B9 is a highlight of the HF-Series range.

The high quality BNP core has the best cooling properties to provide optimum performance even in poor conditions and is also very robust.

It is characterized by a high resistance and heats itself not so much as comparable networks of other manufacturers. At the same time the whole system is also aligned to the best flow. This means that the pressure loss is minimal and the entire air flow was aerodynamically designed with CAD-flow analyzes. Also included are the cooler boxes, which are made of high-strength aluminum casting and equipped with our WAY FIN TECHNOLOGY.

Technical Details
Cast: Aluminium
Core: Bar´n´Plate
Incl. parts certificate for problem-free registration according to §19.3

Note: Not suitable in combination with our HF-Series additional air baffle for A4/A5 and S4/S5.

The advantages of this product are:

1. Improved flow and uniform pressure distribution for maximum efficiency:

2. Less Pressure Drop:

With a higher pressure loss the turbocharger has to drive a higher RPM to achieve the programmed boost pressure. This results in a higher thermal load of the turbocharger and a higher wear.

 

3. Cooler Charge Air:

4. Earlier Response & Improved Performance:

What will the advantages be, if you are installing an upgrade intercooler?

To name an accurate performance increasement, which results by installing an upgrade intercooler in numbers, many unknown factors, like: further hardware changes, as well as the engine software you are using, have to be determined, because this is different from vehicle to vehicle. As a rule of thumb for ECU remapped engines, you can expect up to 5% - 10%. But what at least also as important is: Regardless whether your ECU is already remapped or if it isn´t, upgrade intercoolers preventing a loss of performance at worse conditions, like high outside temperatures or even to reach the temperature protection of your engine. So you will be always able to count on the full power of it.

Recommendation
Use our HF-Series intercooler to complement your hardware and software setup. By reducing the back-pressure (relieving the turbocharger) and improved cooling of the charged air (increasing the oxygen ratio in the combustion chamber + thermal relief), an increased performance results, which lets you use the potential of any turbo-charged engine efficiently.

If you´re thinking about hardware and software tuning on your vehicle, you shouldn´t ignore the fact „Charge air pressure loss“.

So, if you´re increasing the perfomance of your car by chiptuning, the charge air pressure will increase in 99% oft he cases. The use of the standard charge air cooler increases the load pressure loss exponentially. This means that the turbocharger has to work even more and the thermal load on the turbocharger increases, the running time drops or is weakened by the high speeds of the turbocharger.

With our HF-Series intercoolers, we create the perfect balance between cooling effect and charge air pressure loss.
