HF-Series intercooler kit 540×280×40 mm for VW Polo 9N3 1.8T GTI

This upgrade intercooler kit for the VW Polo 9N 1.8T is a standout product from the HF-Series range. The high-quality B’n’P core provides excellent cooling performance, even under unfavourable conditions, while also being extremely robust. It offers high resistance and does not heat up as much as comparable cores from other manufacturers.

The entire system is also designed for optimum airflow. This means that pressure loss is minimal and the complete charge-air path was developed using CAD flow analyses. This also includes the end tanks, which are made from high-strength cast aluminium.

Product benefits:

• significantly cooler charge air, improving combustion in the engine,
• quicker engine response,
• improved airflow.

This makes the product suitable for both standard power and motorsport applications, as substantially higher power outputs are also possible. Each intercooler was built for the respective vehicle, calculated using flow simulations and tested on an in-house rolling road.

What exactly does an upgraded intercooler provide?

To express the exact power increase from an intercooler in figures, many unknown factors must be taken into account, such as factory power variation, other hardware modifications and the software used during measurement. This differs from vehicle to vehicle. As a rule of thumb for engines with increased power, an increase of up to 5–10 % can be assumed.

At least as important is the fact that, at high outside temperatures, you can prevent a loss of power or even activation of the temperature protection stored in many engine control units. This allows you to rely on the full power of your engine, whether it has already been optimised in software or remains standard.

Recommendation

Use our HF-Series intercoolers in combination 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, creates an effective performance upgrade that makes efficient use of the potential of any turbocharged engine.

When carrying out hardware or software tuning, the factor of charge-air pressure loss must not be overlooked. Increasing the vehicle’s power through chip tuning will also increase charge pressure in 99% of cases. Using the standard intercooler causes charge-pressure loss to rise exponentially. The turbocharger then has to work harder, increasing its thermal load and reducing its service life; high rotational speeds also accelerate wear.

Our HF-Series intercoolers provide the perfect balance between cooling performance and charge-pressure loss.

Suitable for: VW Polo IV (9N).
