HF-Series intercooler for Ford Focus ST Mk.2 225 PS

This upgraded intercooler kit for the Ford Focus II ST is a highlight of the HF-Series range. The high-quality HFT core provides excellent cooling performance, delivering strong performance even under demanding conditions while remaining highly robust. It offers high resistance to heat and does not heat up as much as comparable cores from other manufacturers.

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

Product benefits:

• significantly cooler charge air, improving engine combustion,
• quicker engine response,
• improved flow.

This product is therefore suitable both for standard power levels and for motorsport, as considerably higher power outputs are also possible.

What exactly does an upgraded intercooler provide?

Expressing the exact power increase provided by an intercooler in figures requires many unknown factors to be taken into account, such as factory power variation, other hardware changes and the software used during testing. This varies from vehicle to vehicle. As a rule of thumb for tuned engines, an increase of up to 5–10 % may be expected.

At least equally important is the fact that, at high outside temperatures, an upgraded intercooler helps prevent power loss or the activation of the temperature protection stored in many engine control units. This allows you to rely on the engine delivering its full power, whether it has already been software-tuned or has remained standard.

Recommendation

Use HF-Series intercoolers in combination with hardware and software optimisation. Reducing back pressure, thereby relieving the turbocharger, and cooling the charge air increases the oxygen content in the combustion chamber and reduces thermal load. This allows the potential of any turbocharged engine to be used efficiently.

When carrying out hardware or software tuning, charge-air pressure loss must not be overlooked. If vehicle power is increased through chip tuning, the boost pressure is also increased in 99% of cases. With the standard intercooler, charge-air pressure loss rises exponentially. The turbocharger must work harder as a result, increasing its thermal load and reducing its service life; higher rotational speeds also accelerate wear.

HF-Series intercoolers provide the ideal balance between cooling efficiency and charge-air pressure loss.

Suitable for: Ford Focus II (DA).
